MySensors HVAC
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.
