Generic thermostat does not work

  - platform: generic_thermostat
    name: Bedroom
    heater: switch.bedroom_heat
    target_sensor: sensor.bedroom_temp
    target_temp: 74
    min_temp: 70
    max_temp: 77    
      seconds: 30

This thing does a whole lot of nothing. It sits at idle no matter what. It does not retain any changes I make with the UI as to the target temp. This thing seems useless.

Which version of Home Assistant are you using?

There is a bug in 0.57.0 and 0.57.1 where changing the target temperature does not do anything, or cause any errors.

This is fixed in version 0.57.2

That is likely it, I have 0.57.1

Now it sets the temp but still does not trigger the switch, does it not work with an input boolean?

Just in case anyone is wondering, the solution is to use a fake MQTT switch.

  - platform: mqtt
    name: "Bedroom Heat"
    command_topic: "its/a/fake"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: true

sorry, I don’t know tbh.
I have never used the generic thermostat
Reading through the documentation it looks like it should work with all switches though


I can confirm generic_thermostat now works only with switch devices as heater switch, and not others. input_boolean also does not work for me. I make it work with Template Switch, any switch like MQTT is also option.

I am testing now code changes to make it work with any toggle type device.

I have that problem in 0.59.2.
The generic thermostat does not respond to temperature sensor changes.

do you mean that when you set a new target temperature in the GUI, this has no impact on the actual target temperature of the thermostat?

For those interested to use input_boolean, I used this code below when I wanted to test before I got an actual switch:

  - platform: template
        value_template: "{{ is_state('input_boolean.demo_heater_zone_1', 'on') }}"
          service: input_boolean.turn_on
            entity_id: input_boolean.demo_heater_zone_1
          service: input_boolean.turn_off
            entity_id: input_boolean.demo_heater_zone_1

This way you use the switch which stores it’s state in an input_boolean

I have a problem with generic thermostat . The Climate panel is not displayed until the heat sensor detects a temperature change. This happens after restarting HA or plugging in, Raspberry PI. I use Hasbian with Raspberry PI and HA 0.62.1. In other versions I did not have such a problem.

Have a look at and see if it helps solve your problem

I’me facing the same issues:

Also missing the dual function for Heating and Cooling with my heatpump.

@pascalsaul If you want to have AUTO (healing/cooling) you can try the version in this PR: If you find any problems, just write a comment on the PR.
