nasa/temperature sensor

[titof2375]

Hello, can we tell the air conditioning to regulate the temperature in relation to another temperature sensor than the one in the air conditioning?

[DerTiger1]

@titof2375: Yes it's possible. You can use any homeassistant Sensors for temperature and the thermostat to regulate the temperature as an add-on in esphome. Here is my working config with home assistant sensor reading "sensor.meter_og_temperature": (Sorry for the formatting of the comments all '#' lead to bold)

  You could use the ESPHome/Homeassist climate control

  And/or use seperate controls/sensors

Are these the sensors that you declare for the Samsung AC air conditioning driver?

[DerTiger1]

Yes, the first one is a temperature sensor, the second one is meant to be the setpoint value, but not used yet.

[titof2375]

so the samsung air conditioning takes the temperature from the sensor.meter_og_temperature probe

[DerTiger1]

not directly - the thermostat takes the temperature and regulates the samsung hvac. (connected by the id: klima) At least the behavior is the same.
