hvac_mode_template

[cserem]

The problem

Hello!

I have a climate with hvac_mode_template like so: hvac_mode_template: "{% if is_state('sensor.th2_mode_state', 'HOT') -%}heat{%- else -%}cool{%- endif %}" set_hvac_mode: some actions, which work otherwise

If i change sensor.th2_mode_state by other means, then the UI is updated properly.

The problem is, that if I set the hvac_mode_template template I am no longer able to change the modes on the UI (clicking the flame or snowflake icon doen't do anything)

If I omit the hvac_mode_template, clicking on the icons works again.

Is this the expected behaviour? If so, how could I use the mode selection while providing its status from an external source?

Thanks, M

I have exact the same problem. I dont think this is normal :/

The way you can do this is by using the variable that gets exposed to the action:

    set_hvac_mode:
      - service: esphome.bedroom
        data:
          hvac_mode: "{{ hvac_mode }}"

Actions are essentially scripts, and they expose variables for you to use.

Hope this helps!

But how can i achieve this when i calling a script to set the hvac mode? I use this integration to send commands to a knx bus, without hvac_mode_template i call a script and the commands to knx are working fine but i dont have synchronization with wall mounts controllers of the aircondition. When i use hvac_mode_template i have the synchronization but i can not command them (run the scripts). Any idea would be extremely helpfully.

@harisma-git I have the same issue, have you been able to find a way to do it ?

[harisma-git]

Unfortunately, no. I have it without synchronization :/

Thanks @harisma-git.

@jcwillox any ideas ?

You can pass a variable to a script when you call it in Home Assistant.

let's consider we have the following script:

# Example script
script:
  my_script:
    sequence:
      - service: notify.mobile_app
        data:
          message: "Received value: {{ value }}"

Now let's call the above example script with an automation and pass a value in a variable:

automation:
  - alias: Call Script with Variable
    trigger:
      platform: state
      entity_id: binary_sensor.motion_sensor
      to: 'on'
    action:
      - service: script.turn_on
        entity_id: script.my_script
        data_template:
          value: "Hello, World!"

So in the case of the set_hvac_mode you'll do something like this:

    set_hvac_mode:
      - service: script.turn_on
        entity_id: script.my_script
        data_template:
          value: "{{ hvac_mode }}"

I hope this helps.

@Tonguc-Endem I dont think this is SUPPOSED to be how this works, but it does seem to work!

Same issue for me

I've been encountering a similar issue. In my case, I'm using a physical switch controls my air conditioning (AC) unit in the bedroom. My goal was to ensure that any changes in the AC's operational state via the physical switch were accurately reflected within the Climate entity in Home Assistant, and vice versa.

To achieve this, I removed hvac_mode_template and leveraged set_hvac_mode to directly control the switch based on the HVAC mode changes. Here's the relevant part of my configuration:

climate:
- platform: climate_template
  ...
  set_hvac_mode:
    - service: switch.turn_{{ 'off' if hvac_mode == 'off' else 'on' }}
      entity_id: switch.bedroom_ac_switch

This configuration snippet ensures that when the HVAC mode of the Climate entity is set to "off" within Home Assistant, the corresponding switch (switch.bedroom_ac_switch in my case) is turned off. Conversely, setting any other mode (implicitly including "auto") turns the switch on, effectively powering the AC unit.

Additionally, I implemented an automation to handle state changes from the physical switch and update the Climate entity's mode accordingly:

automation:
  - id: bedroom-ac-switch-sync
    alias: Bedroom AC Switch Sync
    trigger:
      - platform: state
        entity_id: switch.bedroom_ac_switch
    action:
      - service: climate.set_hvac_mode
        target:
          entity_id: climate.bedroom_ac
        data:
          hvac_mode: "{{ 'auto' if is_state('switch.bedroom_ac_switch', 'on') else 'off' }}"

This automation ensures that manual toggles of the physical switch are reflected in the Climate entity's operational mode, thus maintaining consistency between the physical switch state and the virtual climate control within Home Assistant.

Thanks @Tonguc-Endem and @harisma-git for your guidance.
