With the thermostat, sensors are available to visualize alerts and the internal state of the thermostat. These are available in the entities of the device associated with the thermostat:
In order, there are:
- the main
climateentity for thermostat control, - the entity allowing the auto-start/stop feature,
- the entity allowing VTherm to follow changes in the underlying device,
- the energy consumed by the thermostat (value that increments continuously),
- the time of receipt of the last external temperature,
- the time of receipt of the last internal temperature,
- the average power of the device during the cycle (for TPI only),
- the time spent in the off state during the cycle (TPI only),
- the time spent in the on state during the cycle (TPI only),
- the load shedding state,
- the power percentage during the cycle (TPI only),
- the presence state (if presence management is configured),
- the security state,
- the window state (if window management is configured),
- the motion state (if motion management is configured),
- the valve opening percentage (for
over_valvetype),
The presence of these entities depends on whether the associated feature is enabled.
To color the sensors, add these lines and customize them as needed in your configuration.yaml:
frontend:
themes:
versatile_thermostat_theme:
state-binary_sensor-safety-on-color: "#FF0B0B"
state-binary_sensor-power-on-color: "#FF0B0B"
state-binary_sensor-window-on-color: "rgb(156, 39, 176)"
state-binary_sensor-motion-on-color: "rgb(156, 39, 176)"
state-binary_sensor-presence-on-color: "lightgreen"
state-binary_sensor-running-on-color: "orange"and choose the theme versatile_thermostat_theme in the panel configuration. You will get something like this:
This custom implementation offers specific actions (services) to facilitate integration with other Home Assistant components.
This service allows you to force the presence state independently of the presence sensor. This can be useful if you want to manage presence via a service rather than a sensor. For example, you can use your alarm to force absence when it is turned on.
The code to call this service is as follows:
service : versatile_thermostat.set_presence
Les données:
présence : "off"
cible:
entity_id : climate.my_thermostatThis service is useful if you want to dynamically change the preset temperature. Instead of switching presets, some use cases require modifying the temperature of the preset. This way, you can keep the scheduler unchanged to manage the preset while adjusting the preset temperature. If the modified preset is currently selected, the target temperature change is immediate and will be applied in the next calculation cycle.
You can modify one or both temperatures (when present or absent) of each preset.
Use the following code to set the preset temperature:
service: versatile_thermostat.set_preset_temperature
data:
preset: boost
temperature: 17.8
temperature_away: 15
target:
entity_id: climate.my_thermostatOr, to change the preset for the Air Conditioning (AC) mode, add the _ac prefix to the preset name like this:
service: versatile_thermostat.set_preset_temperature
data:
preset: boost_ac
temperature: 25
temperature_away: 30
target:
entity_id: climate.my_thermostat
Notes
- After a restart, presets are reset to the configured temperature. If you want your change to be permanent, you need to modify the preset temperature in the integration configuration.
This service allows you to dynamically modify the security settings described here Advanced Configuration.
If the thermostat is in security mode, the new settings are applied immediately.
To change the security settings, use the following code:
service: versatile_thermostat.set_safety
data:
min_on_percent: "0.5"
default_on_percent: "0.1"
delay_min: 60
target:
entity_id: climate.my_thermostatThis service allows you to enable or disable a bypass for the window check.
It allows the thermostat to continue heating even if the window is detected as open.
When set to true, changes to the window's status will no longer affect the thermostat. When set to false, the thermostat will be disabled if the window is still open.
To change the bypass setting, use the following code:
service: versatile_thermostat.set_window_bypass
data:
bypass: true
target:
entity_id: climate.my_thermostatThe key events of the thermostat are notified via the message bus. The following events are notified:
versatile_thermostat_security_event: the thermostat enters or exits thesecuritypresetversatile_thermostat_power_event: the thermostat enters or exits thepowerpresetversatile_thermostat_temperature_event: one or both temperature measurements of the thermostat haven't been updated for more than `safety_delay_min`` minutesversatile_thermostat_hvac_mode_event: the thermostat is turned on or off. This event is also broadcast at the thermostat's startupversatile_thermostat_preset_event: a new preset is selected on the thermostat. This event is also broadcast at the thermostat's startupversatile_thermostat_central_boiler_event: an event indicating a change in the boiler's stateversatile_thermostat_auto_start_stop_event: an event indicating a stop or restart made by the auto-start/stop function
If you've followed along, when a thermostat switches to security mode, 3 events are triggered:
versatile_thermostat_temperature_eventto indicate that a thermometer is no longer responding,versatile_thermostat_preset_eventto indicate the switch to thesecuritypreset,versatile_thermostat_hvac_mode_eventto indicate the potential shutdown of the thermostat
Each event carries the event's key values (temperatures, current preset, current power, ...) as well as the thermostat's states.
You can easily capture these events in an automation, for example, to notify users.
To adjust the algorithm, you have access to the entire context seen and calculated by the thermostat via dedicated attributes. You can view (and use) these attributes in the "Developer Tools / States" section of HA. Enter your thermostat and you will see something like this:
