Please help me get started

So here I am, starting from scratch. Will this create a basic climate entity (my configuration file contains: climate: !include climate.yaml) so it is being loaded.

  - platform: smart_thermostat
    name: Lounge Heating
    unique_id: lounge_heating
    heater: input_boolean.heating_lounge
    target_sensor: sensor.loungetemphum_temperature
    precision: 0.1
    target_temp_step: 0.5
    min_temp: 8
    max_temp: 26
    ac_mode: False
    target_temp: 12
    keep_alive:
      seconds: 60
    away_temp: 12
    kp: 100
    ki: 0
    kd: 0
    ke: 0
    pwm: 0
    min_cycle_duration: 00:05:00
    min_off_cycle_duration: 00:05:00

The result is a climate entity, which currently measures say 20 C and I have set the target temp to 22 C in the hopes that this would flip the input boolean to ON and yet it doesn't.

Isn't that how this is supposed to work?

I have further automations down the line, i.e. what should happen when that input booleans gets set to ON or OFF but shouldn't this code above trigger the boolean when the measured temp goes above or below the target temp?

Please help, it seems I am failing at the very beginning :-)

I realize I am so totally, utterly lost about how this works. It turns out the input_boolean helper activates hvac_action: heat I am lost.

Can somebody please explain the connection between this smart thermostat I have created and my input_bolean helper and my thermostat card? Who triggers what.

In the state shown below, if I switch the input helper to ON, the smart thermostat will turn from hvac_action: idle to hvac_action: heat but shouldn't it be the other way around, I mean the smart thermostat should realize this is unnecessary since the target temp is above the measured temp?

Please give me a hand, I struggled for almost 3 years with Better Thermostat and other solutions due to TRV incompatibilities hence I turned to smart thermostat thinking this should work. Unfortunately, I seem to be unable to connect the dots.

When using a switch or boolean entity as heater, the PWM must not be 0. Set it to 15 minutes for example.

Home assistant monitors the state of the heater entity to report the actual operation of the thermostat. So it will change in the UI either if the boolean is toggled manually or if it's driven by the thermostat.

Thanks, this solved the problem. I misread the documentation, thinking that I was using a valve underneath but I had actually deployed an input boolean on top of it.
