+> ![Tip](images/tips.png) This thermostat integration aims to drastically simplify your automations around climate management. Because all classical events in climate are natively handled by the thermostat (nobody at home ?, activity detected in a room ?, window open ?, power shedding ?), you don't have to build over complicated scripts and automations to manage your climates ;-).

 Give the main mandatory attributes:
 1. a name (will be the integration name and also the climate entity name)
 2. an equipment entity id which represent the heater. This equipment should be able to switch on or off,
-3. a sensor entity id which gives the temperature of the room in which the heater is installed,
-4. a cycle duration in minutes. At each cycle, the heater will be turned on then off for a calculated period in order to reach the targeted temperature (see presents below)
-5. a function used by the algorithm. 'linear' is the most common function. 'atan' is more aggressive and the targeted temperature will be reach sooner (but the power consumption is greater). Use it for room badly isolated,
-6. a bias value of type float. Proportional algorithm are known to never reach the targeted temperature. Depending of the room and heater configuration set a bias to reach the target. To evaluate the correct value, set it to 0, set the preset to a target temperature and see the current temperature reach. If it is below the target temperature, set the bias accordingly.
+3. a temporature sensor entity id which gives the temperature of the room in which the heater is installed,
+4. a temperature sensor entity giving the external temperature. If don't have any external sensor, you can use the local meteo integration
+5. a cycle duration in minutes. At each cycle, the heater will be turned on then off for a calculated period in order to reach the targeted temperature (see [preset](#configure-the-preset-temperature) below),
+6. Algorithm to use. Today only the TPI algorithm is available. See [algorithm](#algorithm)
+
+> ![Tip](images/tips.png) _*Notes*_
+      1. Calculation are done at each cycle. So in case of conditions change, you will have to wait for the next cycle to see a change. For this reason, the cycle should not be too long. **5 min is a good value**,
+      2. if the cycle is too short, the heater could never reach the target temperature indeed for heater with accumulation features and it will be unnecessary solicited

-Concerning the preset modes, you first have to know that, as defined in the core development documentation (https://developers.home-assistant.io/docs/core/entity/climate/), the preset mode handled are the following :
- - ECO : Device is running an energy-saving mode
- - AWAY :	Device is in away mode
- - BOOST : Device turn all valve full up
- - COMFORT :	Device is in comfort mode
- - POWER :	An extra preset used when the power management detects an overpowering situation
+The preset mode allows you to pre-configurate targeted temperature. Used in conjonction with Scheduler (see [scheduler](#even-better-with-scheduler-component) you will have a powerfull and simple way to optimize the temperature vs electrical consumption of your hous. Preset handled are the following :
+ - **Eco** : device is running an energy-saving mode
+ - **Comfort** : device is in comfort mode
+ - **Boost** : device turn all valve full up

-'None' is always added in the list of modes, as it is a way to not use the presets modes but a manual temperature instead.

+    1. Changing manually the target temperature, set the preset to None (no preset). This way you can always set a target temperature even if no preset are available.
+    2. standard **Away** preset is a hidden preset which is not directly selectable. Versatile Thermostat uses the presence management or movement management to set automatically and dynamically the target temperature depending on a presence in the home or an activity in the room. See [presence management](#configure-the-presence-management).
+    3. if you uses the power shedding management, you will see a hidden preset named **power**. The heater preset is set to **power** when overpowering conditions are encountered and shedding is active for this heater. See [power management](#configure-the-power-management).

 Give the following attributes:
-1. an entity id of a window/door sensor. This should be a binary_sensor or a input_boolean. The state of the entity should be 'on' or 'off'

+![image](images/config-motion.png?raw=true)

 We will now see how to configure the new Activity mode.
 What we need:
- a motion sensor. The entity id of a motion sensor. Motion sensor states should be 'on' (motion detected) or 'off' (no motion detected)
- a "motion delay" duration defining how many time we leave the temperature like in "motion" mode after the last motion is detected.
- a target "motion" preset. We will used the same temperature than this preset when an activity is detected.
- a target "no motion" preset. We will used the same temperature than this preset when no activity is detected.
+- a **motion sensor**. The entity id of a motion sensor. Motion sensor states should be 'on' (motion detected) or 'off' (no motion detected)
+- a **motion delay** (in seconds) duration defining how long we wait for motion confirmation before considering the motion
+- a **target "motion" preset**. We will used the temperature of this preset when an activity is detected.
+- a **target "no motion" preset**. We will used the temperature of this second preset when no activity is detected.

 So imagine we want to have the following behavior :
 - we have room with a thermostat set in activity mode, the "motion" mode chosen is comfort (21.5C), the "no motion" mode chosen is Eco (18.5 C) and the motion delay is 5 min.

 ### Configure the power management
-This feature allows you to regulate the power consumption of your radiators.

-This allows you to change the max power along time using a Sceduler or whatever you like.
+This allows you to change the max power along time using a Scheduler or whatever you like.

+> ![Tip](images/tips.png)  _*Notes*_
+    1. When shedding is encountered, the heater is set to the preset named ``power``. This is a hidden preset, you cannot select it manually.
+    2. I use this to avoid exceeded the limit of my electrical power contract when an electrical vehicle is charging. This makes a kind of auto-regulation.
+    3. Always keep a margin, because max power can be briefly exceeded while waiting for the next cycle calculation typically or by not regulated equipement.
+    4. If you don't want to use this feature, just leave the entities id empty
+
+### Configure the presence or occupancy
+This feature allows you to dynamically changes the temperature of all configured Versatile thermostat's presets when nobody is at home or when someone comes back home. For this, you have to configure the temperature that will be used for each preset when presence is off. When the occupancy sensor turns to off, those tempoeratures will be used. When it turns on again the "normal" temperature configured for the preset is used. See [preset management](#configure-the-preset-temperature).
+
+For this you need to configure:
+1. A **occupancy sensor** which state should be 'on' or 'home' if someone is present or 'off' or 'not_home' else,
+2. The **temperature used in Eco** preset when absent,
+3. The **temperature used in Comfort** preset when absent,
+4. The **temperature used in Boost** preset when absent
+
+> ![Tip](images/tips.png)  _*Notes*_
+      1. the switch of temperature is immediate and is reflected on the front component. The calculation will take the new target temperature into account at the next cycle calculation,
+      2. you can use direct person.xxxx sensor or group of sensors of Home Assistant. The presence sensor handles ``on`` or ``home`` states as present and ``off`` or ``not_home`` state as absent.

 ## Algorithm
 This integration uses a proportional algorithm. A Proportional algorithm is useful to avoid the oscillation around the target temperature. This algorithm is based on a cycle which alternate heating and stop heating. The proportion of heating vs not heating is determined by the difference between the temperature and the target temperature. Bigger the difference is and bigger is the proportion of heating inside the cycle.
+
 This algorithm make the temperature converge and stop oscillating.

-Depending of your area and heater, the convergente temperature can be under the targeted temperature. So a bias parameter is available to fix this. To find the right value of biais, just set it to 0 (no biais), let the temperature converge and see if it is near the targeted temperature. If not adjust the biais. A good value is 0.25 with my accumulator radiator (which are long to heat but keeps the heat for a long time).
+## TPI algorithm
+The TPI algorithm consist in the calculation at each cycle of a percentage of On state vs Off state for the heater using the target temperature, the current temperature in the room and the current external temperature.

-A function parameter is available. Set it to "Linear" to have a linéar growth of temperature or set it to "Atan" to have a more aggressive curve to target temperature depending of your need.
+The percentage is calculated with this formula:
+
+    on_percent = coef_int * (target temperature - current temperature) + coef_ext * (target temperature - external temperature)
+    Then make 0 <= on_percent <= 1
+
+Defaults values for coef_int and coef_ext are respectively: ``0.6`` and ``0.01``. Those defaults values are suitable for a standard well isolated room.
+
+To tune those coefficients keep in mind that:
+1. **if target temperature is not reach** after stable situation, you have to augment the ``coef_ext`` (the ``on_percent`` is too high),
+2. **if target temperature is exceeded** after stable situation, you have to decrease the ``coef_ext`` (the ``on_percent`` is too low),
+3. **if reaching the target temperature is too slow**, you can increase the ``coef_int`` to give more power to the heater,
+4. **if reaching the target temperature is too fast and some oscillations appears** around the target, you can decrease the ``coef_int`` to give less power to the heater
+
+See some situations at [examples](#some-results).
+
+### Custom attributes
+
+To tune the algorithm you have access to all context seen and calculted by the thermostat through dedicated attributes. You can see (and use) those attributes in the "Development tools / states" HMI of HA. Enter your thermostat and you will see something like this:
