Integrates MySensors HVAC into Home Assistant. See the [main component] for configuration instructions.
|
|
|
|
The following actuator types are supported:
|
|
|
|
##### MySensors version 1.5 and higher
|
|
|
|
S_TYPE | V_TYPE
|
|
-------|-----------------------------------------------------------------------------
|
|
S_HVAC | V_HVAC_FLOW_STATE*, V_HVAC_SETPOINT_HEAT, V_HVAC_SETPOINT_COOL, V_HVAC_SPEED, V_TEMP
|
|
|
|
V_HVAC_FLOW_STATE is mapped to the state of the Climate component in Home Assistant as follows:
|
|
|
|
Home Assistant State | MySensors State
|
|
---------------------|----------------
|
|
STATE_COOL | CoolOn
|
|
STATE_HEAT | HeatOn
|
|
STATE_AUTO | AutoChangeOver
|
|
STATE_OFF | Off
|
|
|
|
Currently humidity, away_mode, aux_heat, swing_mode is not supported. This will be included in later versions as feasible.
|
|
|
|
Set the target temperature using V_HVAC_SETPOINT_HEAT in Heat mode, and V_HVAC_SETPOINT_COOL in Cool Mode. In case of any Auto Change Over mode you can use V_HVAC_SETPOINT_HEAT as well as V_HVAC_SETPOINT_COOL to set the both the low bound and the high bound temperature of the device.
|
|
|
|
You can use V_HVAC_SPEED to control the Speed setting of the Fan in the HVAC.
|
|
|
|
You can use V_TEMP to send the current temperature from the node to Home Assistant.
|
|
