KNX Climate with MQTT Temperature

Configuration
, ,
1

have a knx aktor. but, the actual temperature does not come from the knx bus, it comes from a mqtt sensor.

  • name: Bad
    temperature_address: “4/2/2”
    target_temperature_address: “4/2/3”
    target_temperature_state_address: ???
    setpoint_shift_address: “4/2/78”
    setpoint_shift_state_address: “4/2/78”
    operation_mode_address: “5/1/6”
    operation_mode_state_address: “5/1/6”
    min_temp: 7.0
    max_temp: 32.0

entitie id sensor.xiaomi_htp_bad_eg_temperature

how should the configuration look like here?

Hi :wave:
The knx Integration can only handle values seen on the knx bus.

  • Create a dummy-group-address and assign it to the temperature.
  • Use knx expose to send the HA (mqtt) value to the bus.
  • target_temperature_state_address is not the current room temperature, temperature_address is.
  • when you use setpoint shift better use setpoint_shift_min and Max instead of min_temp (maybe both together can work too)
