You have at least one climate included which does not have heating or cooling. What does it do then?
Can you please try to find the affected entity and share its attributes?

[kimzeuner]

im having the same issue since the last update and im pretty sure that the affected entities are my climate template entities (because since the update they are no longer listed in the hub configuration).
The configuration for the climate template entities look like this

- platform: climate_template
  name: "Fußbodenheizung Wohnzimmer Template"
  unique_id: "fussbodenheizung_wohnzimmer_template"
  modes:
    - "auto"
    - "off"
  preset_modes:
    - "away"
    - "home"
    - "sleep"
    - "boost"
  min_temp: 8
  max_temp: 30
  temp_step: 0.5
  precision: 0.1
  current_temperature_template: "{{ states('sensor.e2m_thermostate_wohnzimmer_tempc') }}"
  set_temperature: 
    - sequence:
      - service: number.set_value
        metadata: {}
        data:
          value: "{{ ((state_attr('climate.fussbodenheizung_wohnzimmer_template', 'temperature')|float(0)) * 6.375)|int }}"
        target:
          entity_id: number.e2m_thermostate_wohnzimmer_setpoint_raw
      - service: number.set_value
        metadata: {}
        data:
          value: "{{ state_attr('climate.fussbodenheizung_wohnzimmer_template', 'temperature')|float() }}"
        target:
          entity_id: number.e2m_thermostate_wohnzimmer_setpoint_temp
  hvac_mode_template: >-
    {% if is_state('binary_sensor.e2m_thermostate_wohnzimmer_nightmode', 'on') %}
      off
    {% else %}
      auto
    {% endif %}

so as you see there are only the hvac modes "auto" and "off".
Because of your hint i have changed "auto" to "heat". Then restarted HA so the config for the climate template is reloaded. After the restart and then restarting the addon the climate entities are back in the hub configuration but the error was still shown. i have then once again restarted the addon and now the error message is gone and the entities are back.

the config for the climate template now looks like this

- platform: climate_template
  name: "Fußbodenheizung Wohnzimmer Template"
  unique_id: "fussbodenheizung_wohnzimmer_template"
  modes:
    - "heat"
    - "off"
  preset_modes:
    - "away"
    - "home"
    - "sleep"
    - "boost"
  min_temp: 8
  max_temp: 30
  temp_step: 0.5
  precision: 0.1
  current_temperature_template: "{{ states('sensor.e2m_thermostate_wohnzimmer_tempc') }}"
  set_temperature: 
    - sequence:
      - service: number.set_value
        metadata: {}
        data:
          value: "{{ ((state_attr('climate.fussbodenheizung_wohnzimmer_template', 'temperature')|float(0)) * 6.375)|int }}"
        target:
          entity_id: number.e2m_thermostate_wohnzimmer_setpoint_raw
      - service: number.set_value
        metadata: {}
        data:
          value: "{{ state_attr('climate.fussbodenheizung_wohnzimmer_template', 'temperature')|float() }}"
        target:
          entity_id: number.e2m_thermostate_wohnzimmer_setpoint_temp
  hvac_mode_template: >-
    {% if is_state('binary_sensor.e2m_thermostate_wohnzimmer_nightmode', 'on') %}
      off
    {% else %}
      heat
    {% endif %}

Thanks!

Okay nice. The problem is that at least heat or cool is needed for matter. There is no way to not have it.

Additionally the "auto mode" in matter is more like the "heat/cool" mode in HA. And it requires heat and cool. For the Auto Mode from HA, I don't find a good match in Matter...

[kimzeuner]

ok i see. For me it doesn`t really matter if it is called auto or heat. When i have created the entities i thought that the auto mode sound better then heat but also heat is ok for me.
Thanks

It was the same problem as already explained by kimzeuner.
