HVAC Fan mode not working

Hi,

I have an MHI airco unit in my living room.
I can controle this unit with an ESP8266 running ESPHome with MHI-AC-Ctrl-ESPHome.

When i try to set the fan speed in HA, it fails.

I have this automation:

service: climate.set_fan_mode
data:
  fan_mode: High
target:
  entity_id: climate.woonkamer_airco

When i run this automation it get an error: Unkown Error.

Does anybody now how to set the fan speed?
In the frontend i can set it to: Low, medium, high and auto.

Thnx.

Maarten

If you go under Development mode and use the state function. What does it say for your climate.woonkamer_airco?

As an example here are my fan modes:

fan_modes:
  - 'on'
  - auto
  - diffuse

Hi,

I’ve got smart things integrated into home assistant.
I know fan_only is available to call upon via services and code, however I cannot seem to find a way to edit the default climate entity to include fan_only under hvac_modes:

i.e. I can manually add “fan_only” mode under hvac modes. However after I press it on the frontend it reverts back to the default climate which includes no “fan_only” mode.

I read somewhere about editing json code to add “fan_only” but where do I find that?
