Help needed with thermostat configuration

Configuration
1

Hi,

I’m new here and very new to YAML, so sorry if this is obvious to everyone else, but I can’t get the thermostat card in HA to switch on/off my thermostat. I want it to control a sonoff basic, running Tasmota, with a AM2301 attached.

Here is the YAML extract for the relevant functions. The switch works in it’s own right, i.e. I can switch it on/off via HA and the sensor also works and can be displayed in HA but no matter what I set the temperature to on the thermostat card, it does not switch the sonoff on/off, it just displays idol even when the temperature is below the set point:

switch:
  - platform: mqtt
    name: "Boiler"
    command_topic: "cmnd/boiler/power"
    state_topic: "stat/boiler/POWER"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    
climate:
  - platform: generic_thermostat
    name: "Thermostat"
    heater: switch.boiler
    target_sensor: sensor.boiler
    min_temp: 7
    max_temp: 26
    min_cycle_duration:
      minutes: 1
    initial_hvac_mode: "off"      
    cold_tolerance: 0.5
    hot_tolerance: 0.5
    away_temp: 7
    precision: 0.1

sensor:
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Room Temp' #AM2302
    unit_of_measurement: '°C'
    value_template: '{{ value_json.AM2301.Temperature }}'
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Room Humidity'
    unit_of_measurement: '%'
    value_template: '{{ value_json.AM2301.Humidity }}'

I’ve had a play around with the configuration.yaml and it now looks like this. The thermostat is seeing the sensor temperature but sits at ‘Idle’ all the time, even when there is a requirement for it to be on:

switch:
  - platform: mqtt
    name: "Lounge Heater"
    state_topic: "stat/boiler/POWER"
    command_topic: "cmnd/boiler/POWER"
    availability_topic: "tele/boiler/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: false
    
climate:
  - platform: generic_thermostat
    name: Thermostat
    heater: switch.lounge_heater
    target_sensor: sensor.temp
    min_temp: 10
    max_temp: 30
    ac_mode: 'False'
    #target_temp: 18
    cold_tolerance: 0.3
    hot_tolerance: 0.3
    away_temp: 11

sensor:
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Temp' #AM2302
    unit_of_measurement: '°C'
    value_template: '{{ value_json.AM2301.Temperature }}'
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Humidity'
    unit_of_measurement: '%'
    value_template: '{{ value_json.AM2301.Humidity }}'

I’m not very familiar with Generic Thermostat but try changing:

ac_mode: 'False'

to:

ac_mode: false

That’s the way it’s shown in the documentation’s example.

@123, that is the solution, thank you very much. Sometimes these things need a fresh pair of eyes, as I was staring at this yaml for ages and never saw that syntax error.

For reference to others who this may be useful to, this is the relevant section of my configuration.yaml, which now functions as expected:

switch:
  - platform: mqtt
    name: "Lounge Heater"
    command_topic: "cmnd/boiler/power"
    state_topic: "stat/boiler/POWER"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    retain: true
    
climate:
  - platform: generic_thermostat
    name: Thermostat
    heater: switch.lounge_heater
    target_sensor: sensor.temp
    min_temp: 10
    max_temp: 30
    ac_mode: false
    #target_temp: 18
    cold_tolerance: 0.3
    hot_tolerance: 0.3
    away_temp: 11

sensor:
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Temp' #AM2302
    unit_of_measurement: '°C'
    value_template: '{{ value_json.AM2301.Temperature }}'
  - platform: mqtt
    state_topic: 'tele/boiler/SENSOR'
    name: 'Humidity'
    unit_of_measurement: '%'
    value_template: '{{ value_json.AM2301.Humidity }}'
