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:
|
|
|
|
|
|
|
|
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: .
|
|
|
|
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°.
|
|
|
|
>  _*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: . |
