Thermal Comfort won't work with the output of HA Helpers as input for temperature and humidity

[thomasvnl]

Hi,

I have a usecase in which I combine the values from multiple sensors via a Min/Max helper set to the "mean/median" option (see: https://www.home-assistant.io/integrations/min_max/). I combine two sensors in two seperate helpers to get a more accurate outdoor temperature and humidity reading. I wanted to use Thermal Comfort to get the additional attributes like Heat Index and Absolute Humidity automatically from these more accurate "virtual" sensors/helpers.

The problem I have is that I cannot use the values of the helpers in the Thermal Comfort integration. It will not accept manual input of the entity id (which I tried as the dropdown would not show them) and only displays a long list of actual sensor inputs I can use.

Is there a way to be able to use helpers as input for Thermal Comfort at the moment or is that something that is not (yet) available?

With kind regards,
Thomas

@thomasvnl It lets you only choose sensors with device classes temperature or humidity:

thermal_comfort/custom_components/thermal_comfort/config_flow.py

Lines 359 to 364 in bb8dda0

	humidity_sensors = get_sensors_by_device_class(
	registry, hass, SensorDeviceClass.HUMIDITY, show_advanced
	)
	temperature_sensors = get_sensors_by_device_class(
	registry, hass, SensorDeviceClass.TEMPERATURE, show_advanced
	)

Could you create a template sensor and add a device_class: temperature or device_class: humidity?

Quick OpenAi Example:

template:
  - sensor:
      - name: "Median Temperatur"
        unit_of_measurement: "°C"
        state: >
          {% set temp1 = states('sensor.temperatur_sensor_1') | float %}
          {% set temp2 = states('sensor.temperatur_sensor_2') | float %}
          {% set temps = [temp1, temp2] %}
          {{ temps | sort | median }}
        device_class: temperature
