+
+## the Versatile Thermostat UI Card
+A dedicated card for the Versatile Thermostat has been developed (based on Better Thermostat). It is available here: [Versatile Thermostat UI Card](https://github.com/jmcollin78/versatile-thermostat-ui-card) and offers a modern view of all the VTherm statuses:
+
+![image](https://github.com/jmcollin78/versatile-thermostat-ui-card/blob/master/assets/1.png?raw=true)
+
+## the Scheduler Component!
+
+To make the most out of the Versatile Thermostat, I recommend using it with the [Scheduler Component](https://github.com/nielsfaber/scheduler-component). The scheduler component provides climate scheduling based on predefined modes. While this feature is somewhat limited with the generic thermostat, it becomes very powerful when paired with the Versatile Thermostat.
+
+Assuming you have installed both the Versatile Thermostat and the Scheduler Component, here’s an example:
+
+In Scheduler, add a schedule:
+
+![image](https://user-images.githubusercontent.com/1717155/119146454-ee1a9d80-ba4a-11eb-80ae-3074c3511830.png)
+
+Choose the "Climate" group, select one (or more) entity, pick "MAKE SCHEME," and click next:
+(You can also choose "SET PRESET," but I prefer "MAKE SCHEME.")
+
+![image](https://user-images.githubusercontent.com/1717155/119147210-aa746380-ba4b-11eb-8def-479a741c0ba7.png)
+
+Define your mode scheme and save:
+
+![image](https://user-images.githubusercontent.com/1717155/119147784-2f5f7d00-ba4c-11eb-9de4-5e62ff5e71a8.png)
+
+In this example, I set ECO mode during the night and when no one is home during the day, BOOST in the morning, and COMFORT in the evening.
+
+I hope this example helps; feel free to share your feedback!
+
+## Regulation curves with Plotly to Fine-Tune Your Thermostat
+You can obtain a curve similar to the one shown in [some results](#some-results) using a Plotly graph configuration by leveraging the thermostat's custom attributes described [here](#custom-attributes):
+
+Replace the values between `[[ ]]` with your own.

+  - [The Auto-Start/Stop Function Algorithm](#the-auto-startstop-function-algorithm)
+
+## The TPI Algorithm
+
+### Configuring the TPI Algorithm Coefficients
+
+If you have selected a thermostat of type `over_switch`, `over_valve`, or `over_climate` with self-regulation in `Direct Valve Control` mode and choose the "TPI" option in the menu, you will land on this page:
+
+![image](images/config-tpi.png)
+
+You need to provide:
+1. the coefficient `coef_int` for the TPI algorithm,
+2. the coefficient `coef_ext` for the TPI algorithm.
+
+### Principle
+
+The TPI algorithm calculates the On vs Off percentage for the radiator at each cycle, using the target temperature, the current room temperature, and the current outdoor temperature. This algorithm is only applicable for Versatile Thermostats operating in `over_switch` and `over_valve` modes.
+
+The percentage is calculated using this formula:
+
+    on_percent = coef_int * (target_temperature - current_temperature) + coef_ext * (target_temperature - outdoor_temperature)
+    Then, the algorithm ensures that 0 <= on_percent <= 1.
+
+The default values for `coef_int` and `coef_ext` are `0.6` and `0.01`, respectively. These default values are suitable for a standard well-insulated room.
+
+When adjusting these coefficients, keep the following in mind:
+1. **If the target temperature is not reached** after stabilization, increase `coef_ext` (the `on_percent` is too low),
+2. **If the target temperature is exceeded** after stabilization, decrease `coef_ext` (the `on_percent` is too high),
+3. **If reaching the target temperature is too slow**, increase `coef_int` to provide more power to the heater,
+4. **If reaching the target temperature is too fast and oscillations occur** around the target, decrease `coef_int` to provide less power to the radiator.
+
+In `over_valve` mode, the `on_percent` value is converted to a percentage (0 to 100%) and directly controls the valve's opening level.
+
+## The Self-Regulation Algorithm (Without Valve Control)
+
+The self-regulation algorithm can be summarized as follows:
+
+1. Initialize the target temperature as the VTherm setpoint,
+2. If self-regulation is enabled:
+   1. Calculate the regulated temperature (valid for a VTherm),
+   2. Use this temperature as the target,
+3. For each underlying device of the VTherm:
+     1. If "Use Internal Temperature" is checked:
+          1. Calculate the compensation (`trv_internal_temp - room_temp`),
+     2. Add the offset to the target temperature,
+     3. Send the target temperature (= regulated_temp + (internal_temp - room_temp)) to the underlying device.
+
+## The Auto-Start/Stop Function Algorithm
+
+The algorithm used in the auto-start/stop function operates as follows:
+1. If "Enable Auto-Start/Stop" is off, stop here.
+2. If VTherm is on and in Heating mode, when `error_accumulated` < `-error_threshold` -> turn off and save HVAC mode.
+3. If VTherm is on and in Cooling mode, when `error_accumulated` > `error_threshold` -> turn off and save HVAC mode.
+4. If VTherm is off and the saved HVAC mode is Heating, and `current_temperature + slope * dt <= target_temperature`, turn on and set the HVAC mode to the saved mode.
+5. If VTherm is off and the saved HVAC mode is Cooling, and `current_temperature + slope * dt >= target_temperature`, turn on and set the HVAC mode to the saved mode.
+6. `error_threshold` is set to `10 (° * min)` for slow detection, `5` for medium, and `2` for fast.
+
+`dt` is set to `30 min` for slow, `15 min` for medium, and `7 min` for fast detection levels.
+
+The function is detailed [here](https://github.com/jmcollin78/versatile_thermostat/issues/585).

+
+# Choosing Basic Attributes
+
+Select the "Main Attributes" menu.
+
+![image](images/config-main.png)
+
+Provide the mandatory main attributes. These attributes are common to all VTherms:
+1. A name (this will be both the integration's name and the `climate` entity name),
+2. An entity ID of a temperature sensor that provides the room temperature where the radiator is installed,
+3. An optional sensor entity providing the last seen date and time of the sensor (`last_seen`). If available, specify it here. It helps prevent safety shutdowns when the temperature is stable, and the sensor stops reporting for a long time (see [here](troubleshooting.md#why-does-my-versatile-thermostat-go-into-safety-mode)),
+4. A cycle duration in minutes. At each cycle:
+   1. For `over_switch`: VTherm will turn the radiator on/off, modulating the proportion of time it is on,
+   2. For `over_valve`: VTherm will calculate a new valve opening level and send it if it has changed,
+   3. For `over_climate`: The cycle performs basic controls and recalculates the self-regulation coefficients. The cycle may result in a new setpoint sent to underlying devices or a valve opening adjustment in the case of a controllable TRV.
+5. The equipment's power, which will activate power and energy consumption sensors for the device. If multiple devices are linked to the same VTherm, specify the total maximum power of all devices here,
+6. The option to use additional parameters from centralized configuration:
+   1. Outdoor temperature sensor,
+   2. Minimum/maximum temperature and temperature step size,
+7. The option to control the thermostat centrally. See [centralized control](#centralized-control),
+8. A checkbox if this VTherm is used to trigger a central boiler.
+
+> ![Tip](images/tips.png) _*Notes*_
+>  1. With the `over_switch` and `over_valve` types, calculations are performed at each cycle. In case of changing conditions, you will need to wait for the next cycle to see a change. For this reason, the cycle should not be too long. **5 minutes is a good value**, but it should be adjusted to your heating type. The greater the inertia, the longer the cycle should be. See [Tuning examples](tuning-examples.md).
+>  2. If the cycle is too short, the radiator may never reach the target temperature. For example, with a storage heater, it will be unnecessarily activated.
+
+# Choosing the features to Use
+
+Select the "Features" menu.
+
+![image](images/config-features.png)
+
+Choose the features you want to use for this VTherm:
+1. **Opening detection** (doors, windows) stops heating when an opening is detected. (see [managing openings](feature-window.md)),
+2. **Motion detection**: VTherm can adjust the target temperature when motion is detected in the room. (see [motion detection](feature-motion.md)),
+3. **Power management**: VTherm can stop a device if the power consumption in your home exceeds a threshold. (see [load-shedding management](feature-power.md)),
+4. **Presence detection**: If you have a sensor indicating presence or absence in your home, you can use it to change the target temperature. See [presence management](feature-presence.md). Note the difference between this function and motion detection: presence is typically used at the home level, while motion detection is more room-specific.
+5. **Automatic start/stop**: For `over_climate` VTherms only. This function stops a device when VTherm detects it will not be needed for a while. It uses the temperature curve to predict when the device will be needed again and turns it back on at that time. See [automatic start/stop management](feature-auto-start-stop.md).
+
+> ![Tip](images/tips.png) _*Notes*_
+> 1. The list of available functions adapts to your VTherm type.
+> 2. When you enable a function, a new menu entry is added to configure it.
+> 3. You cannot validate the creation of a VTherm if all parameters for all enabled functions have not been configured.

+> There are three ways to work with VTherms:
+> 1. Each Versatile Thermostat is fully configured independently. Choose this option if you do not want any centralized configuration or management.
+> 2. Some aspects are configured centrally. For example, you can define the minimum/maximum temperatures, open window detection parameters, etc., at a single central instance. For each VTherm you configure, you can then choose to use the central configuration or override it with custom parameters.
+> 3. In addition to centralized configuration, all VTherms can be controlled by a single `select` entity called `central_mode`. This feature allows you to stop/start/set frost protection/etc. for all VTherms at once. For each VTherm, you can specify if it is affected by this `central_mode`.
+
+## Creating a New Versatile Thermostat
+
+Click on "Add Integration" on the integration page (or click 'Add device' in the integration page)
+
+![image](images/add-an-integration.png)
+
+then:
+
+![image](images/config-main0.png)
+
+The configuration can be modified via the same interface. Simply select the thermostat to modify, press "Configure," and you will be able to change some parameters or settings.
+
+Follow the configuration steps by selecting the menu option to configure.
+
+# Choosing a VTherm Type
+
+## Centralized configuration
+This option allows you to configure certain repetitive aspects for all VTherms at once, such as:
+1. Parameters for different algorithms (TPI, open window detection, motion detection, power sensors for your home, presence detection). These parameters apply across all VTherms. You only need to enter them once in `Centralized Configuration`. This configuration does not create a VTherm itself but centralizes parameters that would be tedious to re-enter for each VTherm. Note that you can override these parameters on individual VTherms to specialize them if needed.
+2. Configuration for controlling a central heating system,
+3. Certain advanced parameters, such as safety settings.
+
+## VTherm over a switch
+This VTherm type controls a switch that turns a radiator on or off. The switch can be a physical switch directly controlling a radiator (often electric) or a virtual switch that can perform any action when turned on or off. The latter type can, for example, control pilot wire switches or DIY pilot wire solutions with diodes. VTherm modulates the proportion of time the radiator is on (`on_percent`) to achieve the desired temperature. If it is cold, it turns on more frequently (up to 100%); if it is warm, it reduces the on time.
+
+The underlying entities for this type are `switches` or `input_booleans`.
+
+## VTherm over another thermostat
+When your device is controlled by a `climate` entity in Home Assistant and you only have access to this, you should use this VTherm type. In this case, VTherm simply adjusts the target temperature of the underlying `climate` entity.
+
+This type also includes advanced self-regulation features to adjust the setpoint sent to the underlying device, helping to achieve the target temperature faster and mitigating poor internal regulation. For example, if the device's internal thermometer is too close to the heating element, it may incorrectly assume the room is warm while the setpoint is far from being achieved in other areas.
+
+Since version 6.8, this VTherm type can also regulate directly by controlling the valve. Ideal for controllable TRVs, this type is recommended if you have such devices.
+
+The underlying entities for this VTherm type are exclusively `climate`.
+
+## VTherm over a valve
+If the only entity available to regulate your radiator's temperature is a `number` entity, you should use the `over_valve` type. VTherm adjusts the valve opening based on the difference between the target temperature and the actual room temperature (and the outdoor temperature, if available).
+
+This type can be used for TRVs without an associated `climate` entity or other DIY solutions exposing a `number` entity.
+
+# Making the right choice
+> ![Tip](images/tips.png) _*How to Choose the Type*_
+> Choosing the correct type is crucial. It cannot be changed later via the configuration interface. To make the right choice, consider the following questions:
+> 1. **What type of equipment will I control?** Follow this order of preference:
+>    1. If you have a controllable thermostatic valve (TRV) in Home Assistant through a `number` entity (e.g., a Shelly TRV), choose the `over_valve` type. This is the most direct type and ensures the best regulation.
+>    2. If you have an electric radiator (with or without a pilot wire) controlled by a `switch` entity to turn it on/off, then the `over_switch` type is preferable. Regulation will be managed by the Versatile Thermostat based on the temperature measured by your thermometer at its placement location.
+>    3. In all other cases, use the `over_climate` mode. You retain your original `climate` entity, and the Versatile Thermostat "only" controls the on/off state and target temperature of your original thermostat. Regulation is handled by your original thermostat in this case. This mode is particularly suited for all-in-one reversible air conditioning systems exposed as a `climate` entity in Home Assistant. Advanced self-regulation can achieve the setpoint faster by forcing the setpoint or directly controlling the valve when possible.
+> 2. **What type of regulation do I want?** If the controlled equipment has its own built-in regulation mechanism (e.g., HVAC systems, certain TRVs) and it works well, choose `over_climate`. For TRVs with a controllable valve in Home Assistant, the `over_climate` type with `Direct Valve Control` self-regulation is the best choice.

+# Advanced Configuration
+
+- [Advanced Configuration](#advanced-configuration)
+  - [Advanced Settings](#advanced-settings)
+    - [Minimum Activation Delay](#minimum-activation-delay)
+    - [Safety Mode](#safety-mode)
+
+These settings refine the thermostat's operation, particularly the safety mechanism for a _VTherm_. Missing temperature sensors (room or outdoor) can pose a risk to your home. For instance, if the temperature sensor gets stuck at 10°C, the `over_climate` or `over_valve` _VTherm_ types will command maximum heating of the underlying devices, which could lead to room overheating or even property damage, at worst resulting in a fire hazard.
+
+To prevent this, _VTherm_ ensures that thermometers report values regularly. If they don't, the _VTherm_ switches to a special mode called Safety Mode. This mode ensures minimal heating to prevent the opposite risk: a completely unheated home in the middle of winter, for example.
+
+The challenge lies in that some thermometers—especially battery-operated ones—only send temperature updates when the value changes. It is entirely possible to receive no temperature updates for hours without the thermometer failing. The parameters below allow fine-tuning of the thresholds for activating Safety Mode.
+
+If your thermometer has a `last seen` attribute indicating the last contact time, you can specify it in the _VTherm_'s main attributes to greatly reduce false Safety Mode activations. See [configuration](base-attributes.md#choosing-base-attributes) and [troubleshooting](troubleshooting.md#why-does-my-versatile-thermostat-switch-to-safety-mode).
+
+For `over_climate` _VTherms_, which self-regulate, Safety Mode is disabled. In this case, there is no danger, only the risk of an incorrect temperature.
+
+## Advanced Settings
+
+The advanced configuration form looks like this:
+
+![image](images/config-advanced.png)
+
+### Minimum Activation Delay
+
+The first delay (`minimal_activation_delay_sec`) in seconds is the minimum acceptable delay to turn on the heating. If the calculated activation time is shorter than this value, the heating remains off. This parameter only applies to _VTherm_ with cyclic triggering `over_switch`. If the activation time is too short, rapid switching will not allow the device to heat up properly.
+
+### Safety Mode
+
+The second delay (`security_delay_min`) is the maximum time between two temperature measurements before the _VTherm_ switches to Safety Mode.
+
+The third parameter (`security_min_on_percent`) is the minimum `on_percent` below which Safety Mode will not be activated. This setting prevents activating Safety Mode if the controlled radiator does not heat sufficiently. In this case, there is no physical risk to the home, only the risk of overheating or underheating.
+Setting this parameter to `0.00` will trigger Safety Mode regardless of the last heating setting, whereas `1.00` will never trigger Safety Mode (effectively disabling the feature). This can be useful to adapt the safety mechanism to your specific needs.
+
+The fourth parameter (`security_default_on_percent`) defines the `on_percent` used when the thermostat switches to `security` mode. Setting it to `0` will turn off the thermostat in Safety Mode, while setting it to a value like `0.2` (20%) ensures some heating remains, avoiding a completely frozen home in case of a thermometer failure.
+
+It is possible to disable Safety Mode triggered by missing data from the outdoor thermometer. Since the outdoor thermometer usually has a minor impact on regulation (depending on your configuration), it might not be critical if it's unavailable. To do this, add the following lines to your `configuration.yaml`:
+
+```yaml
+versatile_thermostat:
+...
+    safety_mode:
+        check_outdoor_sensor: false
+```
+
+By default, the outdoor thermometer can trigger Safety Mode if it stops sending data. Remember that Home Assistant must be restarted for these changes to take effect. This setting applies to all _VTherms_ sharing the outdoor thermometer.
+
+> ![Tip](images/tips.png) _*Notes*_
+> 1. When the temperature sensor resumes reporting, the preset will be restored to its previous value.
+> 2. Two temperature sources are required: the indoor and outdoor temperatures. Both must report values, or the thermostat will switch to "security" preset.
+> 3. An action is available to adjust the three safety parameters. This can help adapt Safety Mode to your needs.
+> 4. For normal use, `security_default_on_percent` should be lower than `security_min_on_percent`.
+> 5. If you use the Versatile Thermostat UI card (see [here](additions.md#better-with-the-versatile-thermostat-ui-card)), a _VTherm_ in Safety Mode is indicated by a gray overlay showing the faulty thermometer and the time since its last value update: ![safety mode](images/safety-mode-icon.png).

+- [Auto-start / Auto-stop](#auto-start--auto-stop)
+  - [Configure Auto-start/stop](#configure-auto-startstop)
+  - [Usage](#usage)
+
+This feature allows _VTherm_ to stop an appliance that doesn't need to be on and restart it when conditions require it. This function includes three settings that control how quickly the appliance is stopped and restarted.
+Exclusively reserved for _VTherm_ of type `over_climate`, it applies to the following use case:
+1. Your appliance is permanently powered on and consumes electricity even when heating (or cooling) is not needed. This is often the case with heat pumps (_PAC_) that consume power even in standby mode.
+2. The temperature conditions are such that heating (or cooling) is not needed for a long period: the setpoint is higher (or lower) than the room temperature.
+3. The temperature rises (or falls), remains stable, or falls (or rises) slowly.
+
+In such cases, it is preferable to ask the appliance to turn off to avoid unnecessary power consumption in standby mode.
+
+## Configure Auto-start/stop
+
+To use this feature, you need to:
+1. Add the `With auto-start and stop` function in the 'Functions' menu.
+2. Set the detection level in the 'Auto-start/stop' option that appears when the function is activated. Choose the detection level between 'Slow', 'Medium', and 'Fast'. With the 'Fast' setting, stops and restarts will occur more frequently.
+
+![image](images/config-auto-start-stop.png)
+
+The 'Slow' setting allows about 30 minutes between a stop and a restart,
+The 'Medium' setting sets the threshold to about 15 minutes, and the 'Fast' setting puts it at 7 minutes.
+
+Note that these are not absolute settings since the algorithm takes into account the slope of the room temperature curve to respond accordingly. It is still possible that a restart occurs shortly after a stop if the temperature drops significantly.
+
+## Usage
+
+Once the function is configured, you will now have a new `switch` type entity that allows you to enable or disable auto-start/stop without modifying the configuration. This entity is available on the _VTherm_ device and is named `switch.<name>_enable_auto_start_stop`.
+
+![image](images/enable-auto-start-stop-entity.png)
+
+Check the box to allow auto-start and auto-stop, and leave it unchecked to disable the feature.
+
+> ![Tip](images/tips.png) _*Notes*_
+> 1. The detection algorithm is described [here](algorithms.md#auto-startstop-algorithm).
+> 2. Some appliances (boilers, underfloor heating, _PAC_, etc.) may not like being started/stopped too frequently. If that's the case, it might be better to disable the function when you know the appliance will be used. For example, I disable this feature during the day when presence is detected because I know my _PAC_ will turn on often. I enable auto-start/stop at night or when no one is home, as the setpoint is lowered and it rarely triggers.
+> 3. If you use the Versatile Thermostat UI card (see [here](additions.md#better-with-the-versatile-thermostat-ui-card)), a checkbox is directly visible on the card to disable auto-start/stop, and a _VTherm_ stopped by auto-start/stop is indicated by the icon: ![auto-start/stop icon](images/auto-start-stop-icon.png).

+  - [Warning](#warning)
+
+You can control a centralized boiler. As long as it's possible to trigger or stop the boiler from Home Assistant, Versatile Thermostat will be able to control it directly.
+
+## Principle
+The basic principle is as follows:
+1. A new entity of type `binary_sensor`, named by default `binary_sensor.central_boiler`, is added.
+2. In the configuration of the _VTherms_, you specify whether the _VTherm_ should control the boiler. In a heterogeneous installation, some _VTherms_ should control the boiler, and others should not. Therefore, you need to indicate in each _VTherm_ configuration whether it controls the boiler.
+3. The `binary_sensor.central_boiler` listens for state changes in the equipment of the _VTherms_ marked as controlling the boiler.
+4. When the number of devices controlled by the _VTherm_ requesting heating (i.e., when its `hvac_action` changes to `Heating`) exceeds a configurable threshold, the `binary_sensor.central_boiler` turns `on`, and **if an activation service has been configured, that service is called**.
+5. If the number of devices requesting heating drops below the threshold, the `binary_sensor.central_boiler` turns `off`, and **if a deactivation service has been configured, that service is called**.
+6. You have access to two entities:
+   - A `number` type entity, named by default `number.boiler_activation_threshold`, which gives the activation threshold. This threshold is the number of devices (radiators) requesting heating.
+   - A `sensor` type entity, named by default `sensor.nb_device_active_for_boiler`, which shows the number of devices requesting heating. For example, a _VTherm_ with 4 valves, 3 of which request heating, will make this sensor show 3. Only the devices from _VTherms_ marked to control the central boiler are counted.
+
+You therefore always have the information to manage and adjust the triggering of the boiler.
+
+All these entities are linked to the central configuration service:
+
+![Boiler Control Entities](images/entitites-central-boiler.png)
+
+## Configuration
+To configure this feature, you need a centralized configuration (see [Configuration](#configuration)) and check the 'Add Central Boiler' box:
+
+![Add a Central Boiler](images/config-central-boiler-1.png)
+
+On the next page, you can provide the configuration for the actions (e.g., services) to be called when the boiler is turned on/off:
+
+![Add a Central Boiler](images/config-central-boiler-2.png)
+
+The actions (e.g., services) are configured as described on the page:
+1. The general format is `entity_id/service_id[/attribute:value]` (where `/attribute:value` is optional).
+2. `entity_id` is the name of the entity controlling the boiler in the form `domain.entity_name`. For example: `switch.chaudiere` for a boiler controlled by a switch, or `climate.chaudière` for a boiler controlled by a thermostat, or any other entity that allows boiler control (there is no limitation). You can also toggle inputs (`helpers`) such as `input_boolean` or `input_number`.
+3. `service_id` is the name of the service to be called in the form `domain.service_name`. For example: `switch.turn_on`, `switch.turn_off`, `climate.set_temperature`, `climate.set_hvac_mode` are valid examples.
+4. Some services require a parameter. This could be the 'HVAC Mode' for `climate.set_hvac_mode` or the target temperature for `climate.set_temperature`. This parameter should be configured in the format `attribute:value` at the end of the string.
+
+Examples (to adjust to your case):
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:heat`: to turn the boiler thermostat on in heating mode.
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:off`: to turn off the boiler thermostat.
+- `switch.pompe_chaudiere/switch.turn_on`: to turn on the switch powering the boiler pump.
+- `switch.pompe_chaudiere/switch.turn_off`: to turn off the switch powering the boiler pump.
+- ...
+
+### How to Find the Right Action?
+To find the correct action to use, it's best to go to "Developer Tools / Services", search for the action to call, the entity to control, and any required parameters.
+Click 'Call Service'. If your boiler turns on, you have the correct configuration. Then switch to YAML mode and copy the parameters.
+
+Example:
+
+In "Developer Tools / Actions":
+
+![Service Configuration](images/dev-tools-turnon-boiler-1.png)
+
+In YAML mode:
+
+![Service Configuration](images/dev-tools-turnon-boiler-2.png)
+
+The service to configure will then be: `climate.sonoff/climate.set_hvac_mode/hvac_mode:heat` (note the removal of spaces in `hvac_mode:heat`).
+
+Do the same for the off service, and you’re ready to go.
+
+## Events
+
+Each successful boiler activation or deactivation sends an event from Versatile Thermostat. This can be captured by an automation, for example, to notify you of the change.
+The events look like this:
+
+An activation event:
+```yaml
+event_type: versatile_thermostat_central_boiler_event
+data:
+  central_boiler: true
+  entity_id: binary_sensor.central_boiler

+
+## Warning
+
+> ![Astuce](images/tips.png) _*Notes*_
+>
+> Software or home automation control of a central boiler may pose risks to its proper operation. Before using these functions, ensure that your boiler has proper safety features and that they are functioning correctly. For example, turning on a boiler with all valves closed can create excessive pressure.

+# Centralized Control
+
+- [Centralized Control](#centralized-control)
+  - [Configuration of Centralized Control](#configuration-of-centralized-control)
+  - [Usage](#usage)
+
+This feature allows you to control all your _VTherms_ from a single control point.
+A typical use case is when you leave for an extended period and want to set all your _VTherms_ to frost protection, and when you return, you want to set them back to their initial state.
+
+Centralized control is done from a special _VTherm_ called centralized configuration. See [here](creation.md#centralized-configuration) for more information.
+
+## Configuration of Centralized Control
+
+If you have set up a centralized configuration, you will have a new entity named `select.central_mode` that allows you to control all _VTherms_ with a single action.
+
+![central_mode](images/central-mode.png)
+
+This entity appears as a list of choices containing the following options:
+1. `Auto`: the 'normal' mode where each _VTherm_ operates autonomously,
+2. `Stopped`: all _VTherms_ are turned off (`hvac_off`),
+3. `Heat only`: all _VTherms_ are set to heating mode if supported, otherwise they are stopped,
+4. `Cool only`: all _VTherms_ are set to cooling mode if supported, otherwise they are stopped,
+5. `Frost protection`: all _VTherms_ are set to frost protection mode if supported, otherwise they are stopped.
+
+## Usage
+
+For a _VTherm_ to be controllable centrally, its configuration attribute named `use_central_mode` must be true. This attribute is available in the configuration page `Main Attributes`.
+
+![central_mode](images/use-central-mode.png)
+
+This means you can control all _VTherms_ (those explicitly designated) with a single control.

+# Motion or Activity Detection
+
+- [Motion or Activity Detection](#motion-or-activity-detection)
+  - [Configure Activity Mode or Motion Detection](#configure-activity-mode-or-motion-detection)
+  - [Usage](#usage)
+
+This feature allows you to change presets when motion is detected in a room. If you don't want to heat your office when the room is occupied and only when the room is occupied, you need a motion (or presence) sensor in the room and configure this feature.
+
+This function is often confused with the presence feature. They are complementary but not interchangeable. The 'motion' function is local to a room equipped with a motion sensor, while the 'presence' function is designed to be global to the entire home.
+
+## Configure Activity Mode or Motion Detection
+
+If you have chosen the `With motion detection` feature:
+
+![image](images/config-motion.png)
+
+What we need:
+- a **motion sensor**. Entity ID of a motion sensor. The states of the motion sensor must be "on" (motion detected) or "off" (no motion detected),
+- a **detection delay** (in seconds) defining how long we wait for confirmation of the motion before considering the motion. This parameter can be **greater than your motion sensor's delay**, otherwise, the detection will happen with every motion detected by the sensor,
+- an **inactivity delay** (in seconds) defining how long we wait for confirmation of no motion before no longer considering the motion,
+- a **"motion" preset**. We will use the temperature of this preset when activity is detected,
+- a **"no motion" preset**. We will use the temperature of this second preset when no activity is detected.
+
+## Usage
+
+To tell a _VTherm_ that it should listen to the motion sensor, you must set it to the special 'Activity' preset. If you have installed the Versatile Thermostat UI card (see [here](additions.md#much-better-with-the-versatile-thermostat-ui-card)), this preset is displayed as follows: ![activity preset](images/activity-preset-icon.png).
+
+You can then, upon request, set a _VTherm_ to motion detection mode.
+
+The behavior will be as follows:
+- we have a room with a thermostat set to activity mode, the "motion" mode chosen is comfort (21.5°C), the "no motion" mode chosen is Eco (18.5°C), and the motion delay is 30 seconds on detection and 5 minutes on the end of detection.
+- the room has been empty for a while (no activity detected), the setpoint temperature in this room is 18.5°.
+- someone enters the room, and activity is detected if the motion is present for at least 30 seconds. The temperature then goes up to 21.5°.
+- if the motion is present for less than 30 seconds (quick passage), the temperature stays at 18.5°.
+- imagine the temperature has gone up to 21.5°, when the person leaves the room, after 5 minutes the temperature is returned to 18.5°.
+- if the person returns before the 5 minutes, the temperature stays at 21.5°.
+
+> ![Tip](images/tips.png) _*Notes*_
+> 1. As with other presets, `Activity` will only be offered if it is correctly configured. In other words, all 4 configuration keys must be set.
+> 2. If you are using the Versatile Thermostat UI card (see [here](additions.md#much-better-with-the-versatile-thermostat-ui-card)), motion detection is represented as follows: ![motion](images/motion-detection-icon.png).

+# Power Management - Load Shedding
+
+- [Power Management - Load Shedding](#power-management---load-shedding)
+  - [Configure Power Management](#configure-power-management)
+
+This feature allows you to regulate the electricity consumption of your heaters. Known as load shedding, this feature enables you to limit the electrical consumption of your heating device if overcapacity conditions are detected.
+You will need a **sensor for the total instantaneous power consumption** of your home, as well as a **sensor for the maximum allowed power**.
+
+The behavior of this feature is basic:
+1. when the _VTherm_ is about to turn on a device,
+2. it compares the last known value of the power consumption sensor with the last value of the maximum allowed power. If there is a remaining margin greater than or equal to the declared power of the _VTherm_'s devices, then the _VTherm_ and its devices will be turned on. Otherwise, they will remain off until the next cycle.
+
+WARNING: This very basic operation **is not a safety function** but more of an optimization feature to manage consumption at the cost of heating performance. Overloads may occur depending on the frequency of updates from your consumption sensors, and the actual power used by your devices. Therefore, you must always maintain a safety margin.
+
+Typical use case:
+1. you have an electricity meter limited to 11 kW,
+2. you occasionally charge an electric vehicle at 5 kW,
+3. that leaves 6 kW for everything else, including heating,
+4. you have 1 kW of other equipment running,
+5. you have declared a sensor (`input_number`) for the maximum allowed power at 9 kW (= 11 kW - the reserve for other devices - margin)
+
+If the vehicle is charging, the total power consumed is 6 kW (5+1), and a _VTherm_ will only turn on if its declared power is 3 kW max (9 kW - 6 kW).
+If the vehicle is charging and another _VTherm_ of 2 kW is running, the total power consumed is 8 kW (5+1+2), and a _VTherm_ will only turn on if its declared power is 1 kW max (9 kW - 8 kW). Otherwise, it will wait until the next cycle.
+
+If the vehicle is not charging, the total power consumed is 1 kW, and a _VTherm_ will only turn on if its declared power is 8 kW max (9 kW - 1 kW).
+
+## Configure Power Management
+
+If you have chosen the `With power detection` feature, configure it as follows:
+
+![image](images/config-power.png)
+
+1. the entity ID of the **instantaneous power consumption sensor** for your home,
+2. the entity ID of the **maximum allowed power sensor**,
+3. the temperature to apply if load shedding is activated.
+
+Note that all power values must have the same units (kW or W, for example).
+Having a **maximum allowed power sensor** allows you to adjust the maximum power over time using a scheduler or automation.
+
+> ![Tip](images/tips.png) _*Notes*_
+>
+> 1. In case of load shedding, the radiator is set to the preset named `power`. This is a hidden preset, and you cannot select it manually.
+> 2. Always keep a margin, as the maximum power may briefly be exceeded while waiting for the next cycle calculation, or due to unregulated equipment.
+> 3. If you don't want to use this feature, uncheck it in the 'Functions' menu.
+> 4. If a _VTherm_ controls multiple devices, the **electrical consumption of your heating** must match the sum of the powers.
+> 5. If you are using the Versatile Thermostat UI card (see [here](additions.md#much-better-with-the-versatile-thermostat-ui-card)), load shedding is represented as follows: ![load shedding](images/power-exceeded-icon.png).

+
+If this feature is selected, it allows you to dynamically adjust the preset temperatures of the thermostat when presence (or absence) is detected. To do this, you need to configure the temperature to be used for each preset when presence is disabled. When the presence sensor turns off, these temperatures will be applied. When it turns back on, the "normal" temperature configured for the preset will be used. See [preset management](feature-presets.md).

+
+Temperatures are configured in the entities of the device corresponding to your _VTherm_ (Settings/Integration/Versatile Thermostat/the vtherm).
+

+> 3. To pre-heat your home when everyone is absent, you can add an `input_boolean` entity to your people group. If you set this `input_boolean` to 'On', the presence sensor will be forced to 'On' and the presets with presence will be used. You can also set this `input_boolean` to 'On' via an automation, for example, when you leave a zone to start preheating your home.

+
+The preset mode allows you to pre-configure the target temperature. Used in conjunction with Scheduler (see [scheduler](additions#the-scheduler-component)), you'll have a powerful and simple way to optimize the temperature relative to the electricity consumption in your home. The managed presets are as follows:
+ - **Eco**: the device is in energy-saving mode
+ - **Comfort**: the device is in comfort mode
+ - **Boost**: the device fully opens all valves
+
+If the AC mode is used, you can also configure temperatures when the equipment is in air conditioning mode.
+
+**None** is always added to the list of modes, as it is a way to not use presets but instead set a **manual temperature**.
+
+The presets are configured directly from the _VTherm_ entities or the central configuration if you're using centralized control. Upon creating the _VTherm_, you will have different entities that will allow you to set the temperatures for each preset:
+
+![presets](images/config-preset-temp.png).
+
+The list of entities varies depending on your feature choices:
+1. If the 'presence detection' function is activated, you will have the presets with an "absence" version prefixed with _abs_.
+2. If you have selected the _AC_ option, you will also have presets for 'air conditioning' prefixed with _clim_.
+
+> ![Tip](images/tips.png) _*Notes*_
+>
+> 1. When you manually change the target temperature, the preset switches to None (no preset).
+> 2. The standard preset `Away` is a hidden preset that cannot be directly selected. Versatile Thermostat uses presence management or motion detection to automatically and dynamically adjust the target temperature based on presence in the home or activity in the room. See [presence management](feature-presence.md).
+> 3. If you're using load shedding management, you will see a hidden preset named `power`. The heating element's preset is set to "power" when overload conditions are met and load shedding is active for that heating element. See [power management](feature-power.md).

+
+You must have selected the `With Open Detection` feature on the first page to reach this page.
+Open detection can be done in two ways:
+1. By using a sensor placed on the opening (sensor mode),
+2. By detecting a sudden temperature drop (auto mode)
+
+## Sensor Mode
+To switch to sensor mode, you need to provide an entity of type `binary_sensor` or `input_boolean`.
+In this mode, you need to fill in the following information:
+
+![mode window sensor](images/config-window-sensor.png)
+
+1. A **delay in seconds** before any change. This allows you to open a window quickly without stopping the heating.
+2. The action to take when the opening is detected as open. The possible actions are:
+   1. _Turn off_: the _VTherm_ will be turned off.
+   2. _Fan only_: heating or cooling will be turned off, but the equipment will continue to ventilate (for compatible equipment).
+   3. _Frost protection_: the "Frost Protection" preset temperature will be selected on the _VTherm_ without changing the current preset (see notes below).
+   4. _Eco_: the "Eco" preset temperature will be applied to the _VTherm_ without changing the current preset (see notes below).
+
+When the detector switches to open:
+1. _VTherm_ waits for the specified delay.
+2. If the window is still open after the delay, the _VTherm_ state (Heating / Cooling / ..., current preset, current target temperature) is saved and the action is performed.
+
+Similarly, when the detector switches to closed:
+1. _VTherm_ waits for the specified delay.
+2. If the window is still closed after the delay, the state before the window opening is restored.
+
+## Auto Mode
+In auto mode, the configuration is as follows:
+
+![image](images/config-window-auto.png)
+
+1. A **delay in seconds** before any change. This allows you to open a window quickly without stopping the heating.
+2. A detection threshold in degrees per hour. When the temperature drops beyond this threshold, the thermostat will turn off. The lower this value, the faster the detection (with a higher risk of false positives).
+3. A threshold for ending detection in degrees per hour. When the temperature drop exceeds this value, the thermostat will return to the previous mode (mode and preset).
+4. A maximum detection duration. Beyond this duration, the thermostat will return to its previous mode and preset even if the temperature continues to drop.
+5. The action to take when the opening is detected as open. The actions are the same as in sensor mode described above.
+
+To adjust the thresholds, it is recommended to start with the reference values and adjust the detection thresholds. Some tests gave me the following values (for an office):
+- Detection threshold: 3°C/hour
+- No detection threshold: 0°C/hour
+- Max duration: 30 min.
+
+A new sensor called "slope" has been added for all thermostats. It provides the slope of the temperature curve in °C/hour (or °K/hour). This slope is smoothed and filtered to avoid aberrant thermometer values that could interfere with the measurement.
+
+![image](images/temperature-slope.png)
+
+To adjust it properly, it is recommended to display both the temperature curve and the slope of the curve ("slope") on the same historical graph:
+
+![image](images/window-auto-tuning.png)
+
+> ![Tip](images/tips.png) _*Notes*_
+>
+> 1. If you want to use **multiple door/window sensors** to automate your thermostat, simply create a group with the usual behavior (https://www.home-assistant.io/integrations/binary_sensor.group/)
+> 2. If you don't have a door/window sensor in your room, simply leave the sensor entity ID empty.
+> 3. **Only one mode is allowed**. You cannot configure a thermostat with both a sensor and auto detection. The two modes might contradict each other, so both modes cannot be active at the same time.
+> 4. It is not recommended to use auto mode for equipment subjected to frequent and normal temperature variations (hallways, open areas, etc.).
+> 5. To avoid interfering with your current preset settings, the actions _Frost protection_ and _Eco_ change the target temperature without changing the preset. So, you may notice a discrepancy between the selected preset and the setpoint.
+> 6. If you use the Versatile Thermostat UI card (see [here](additions.md#even-better-with-the-versatile-thermostat-ui-card)), open detection is represented as follows: ![window](images/window-detection-icon.png).

+
+1. Install [HACS](https://hacs.xyz/). This way, you will automatically receive updates.
+2. The Versatile Thermostat integration is now available directly from the HACS interface (Integrations tab).
+3. Search for and install "Versatile Thermostat" in HACS and click "Install".
+4. Restart Home Assistant.
+5. Then, you can add a Versatile Thermostat integration in the Settings / Integrations page. Add as many thermostats as needed (usually one per radiator or group of radiators that need to be controlled, or per pump in the case of a centralized heating system).
+
+## Manual Installation
+
+1. Using your tool of choice, open your Home Assistant configuration directory (where you will find `configuration.yaml`).
+2. If you don't have a `custom_components` directory, you need to create one.
+3. Inside the `custom_components` directory, create a new folder called `versatile_thermostat`.
+4. Download _all_ files from the `custom_components/versatile_thermostat/` directory (folder) in this repository.
+5. Place the downloaded files in the new folder you created.
+6. Restart Home Assistant.
+7. Configure the new Versatile Thermostat integration.

+
+## Prerequisites
+
+The installation should look like this:
+
+![installation `over_climate`](images/over-climate-schema.png)
+
+1. The user or automation, or the Scheduler, sets a setpoint via a preset or directly using a temperature.
+2. Periodically, the internal thermometer (2), external thermometer (2b), or equipment's internal thermometer (2c) sends the measured temperature. The internal thermometer should be placed in a relevant spot for the user's comfort: ideally in the middle of the living space. Avoid placing it too close to a window or equipment.
+3. Based on the setpoint values, differences, and self-regulation parameters (see [auto-regulation](self-regulation.md)), VTherm will calculate a setpoint to send to the underlying `climate` entity.
+4. The `climate` entity controls the equipment using its own protocol.
+5. Depending on the chosen regulation options, VTherm may directly control the opening of a thermostatic valve or calibrate the equipment so that its internal temperature reflects the room temperature.
+
+## Configuration
+
+Click on the "Underlying Entities" option from the menu, and you will see this configuration page:
+
+![image](images/config-linked-entity2.png)
+
+### The Underlying Entities
+In the "Equipment to Control" list, you should add the `climate` entities that will be controlled by VTherm. Only entities of type `climate` are accepted.
+
+### AC Mode
+
+You can choose an `over_climate` thermostat to control an air conditioner (reversible or not) by checking the "AC Mode" box. If the equipment allows it, both 'Heating' and 'Cooling' modes will be available.
+
+### Self-Regulation
+
+In `over_climate` mode, the device uses its own regulation algorithm: it turns on/off and pauses automatically based on the setpoint transmitted by VTherm through its `climate` entity. It uses its internal thermometer and the received setpoint.
+
+Depending on the equipment, this internal regulation may vary in quality. It greatly depends on the quality of the equipment, the functionality of its internal thermometer, and its internal algorithm. To improve equipment that regulates poorly, VTherm offers a way to adjust the setpoint it sends by increasing or decreasing it based on the room temperature measured by VTherm, rather than the internal temperature.
+
+The self-regulation options are described in detail [here](self-regulation.md).
+
+To avoid overloading the underlying equipment (some may beep unpleasantly, others run on batteries, etc.), two thresholds are available to limit the number of requests:
+1. Regulation Threshold: a threshold in ° below which a new setpoint will not be sent. If the last setpoint was 22°, the next one will be 22° ± regulation threshold.
+2. Minimum Regulation Period (in minutes): a minimum time interval below which a new setpoint will not be sent. If the last setpoint was sent at 11:00, the next one cannot be sent before 11:00 + minimum regulation period.
+
+Improperly setting these thresholds may prevent correct self-regulation as new setpoints won't be sent.
+
+### Auto-Fan (Auto Ventilation)
+
+This mode, introduced in version 4.3, forces the use of ventilation if the temperature difference is significant. By activating ventilation, heat distribution occurs more quickly, which helps achieve the target temperature faster.
+You can choose which ventilation level to activate from the following options: Low, Medium, High, Turbo.
+
+Of course, your underlying equipment must have ventilation, and it must be controllable for this to work. If your equipment doesn't include the Turbo mode, the High mode will be used instead. Once the temperature difference becomes small again, the ventilation will switch to a "normal" mode, which depends on your equipment (in order): `Mute`, `Auto`, `Low`. The first available mode for your equipment will be chosen.
+
+### Compensating for the Internal Temperature of the Underlying Equipment
+
+Sometimes, the internal thermometer of the underlying equipment (TRV, air conditioner, etc.) is inaccurate to the point that self-regulation is insufficient. This happens when the internal thermometer is placed too close to the heat source. The internal temperature rises much faster than the room temperature, leading to regulation failures.
+Example:
+1. Room temperature is 18°, setpoint is 20°.
+2. The internal temperature of the equipment is 22°.
+3. If VTherm sends a setpoint of 21° (= 20° + 1° of self-regulation), the equipment will not heat because its internal temperature (22°) is higher than the setpoint (21°).
+
+To address this, a new optional feature has been added in version 5.4: ![Use of Internal Temperature](images/config-use-internal-temp.png)
+
+When activated, this feature adds the difference between the internal temperature and the room temperature to the setpoint to force heating.
+In the above example, the difference is +4° (22° - 18°), so VTherm will send 25° (21° + 4°) to the equipment, forcing it to heat.
+
+This difference is calculated for each underlying equipment since each has its own internal temperature. For example, a VTherm connected to three TRVs, each with its own internal temperature.
+
+This results in much more effective self-regulation that avoids issues with large internal temperature differences due to faulty sensors.
+
+However, be aware that some internal temperatures fluctuate so quickly and inaccurately that they completely skew the calculation. In this case, it’s better to disable this option.
+
+You will find advice on how to adjust these settings properly on the page [self-regulation](self-regulation.md).
+
+## Specific Functions
+
+Specific functions can be configured through a dedicated option in the menu.
+
+The specific functions that require configuration for this type of VTherm are:
+1. Auto-Start/Stop: Automatic start and stop of VTherm based on usage forecasts. This is described here: [auto-start/stop function](feature-auto-start-stop.md).
+2. If valve regulation is chosen, the TPI algorithm configuration is accessible from the menu. See ([algorithms](algorithms.md)).
+
+## Follow Underlying Temperature Changes
+
+Some users want to continue using their equipment as before (without _VTherm_). For example, you might want to use the remote control of your _PAC_ or turn the knob on your _TRV_.
+If you are in this case, an entity has been added to the _VTherm_ device called `Follow underlying temp changes`:
+
+![Track temperature changes](images/entity-follow-under-temp-change.png)
+
+When this entity is 'On', all temperature or state changes made directly on the underlying equipment are reflected in _VTherm_.
+
+Be careful, if you use this feature, your equipment is now controlled in two ways: _VTherm_ and directly by you. The commands might be contradictory, which could lead to confusion about the equipment's state. _VTherm_ is equipped with a delay mechanism that prevents loops: the user gives a setpoint, which is captured by _VTherm_ and changes the setpoint, ... This delay may cause the change made directly on the equipment to be ignored if these changes are too close together in time.
