Hello everyone,
I always had my pellet heater on a sonoff sv with a zero voltage relay. I wired the relay in parallel (with a pulsetime in console) to the pellet heater momentary switch - that I need to hold for 3 seconds, to power it on or off.
The downside of this method is that in HA the on/off state would represent the state of the relay, which does not match the actual power state of the pellet heater. But it was fine for my use case, I just removed the state topic and used payload off = on , so it would also toggle the relay if turned off.
However I just wired in a Pow R2 to the heater, that I want to use to define the state of the heater.
I have set up the sensor in mqtt for the power and total consumption and it shows up fine in HA:
- platform: mqtt
name: "Kachel vermogen"
state_topic: "tele/powr2/SENSOR"
value_template: “{{ value_json['ENERGY'].Power }}”
unit_of_measurement: "W"
I now want to define an “on” state for the pellet heater if the power is above 20 watt and anything below that is off and have come up with some searching with this -probably not functional- uncommented code.
switch:
- platform: mqtt
name: "Kachel"
command_topic: "cmnd/kachel1/POWER"
# state_topic: "tele/powr2/SENSOR"
# value_template: "{{ value_json['ENERGY'].Power 'on' if ( state.state > 20 ) else 'off' }}"
qos: 1
payload_on: "ON"
payload_off: "ON"
Do you guys think this code will work and it will be the best way of going about doing this?
