Disable fan presets

[normal fox]

the matter-over-thread fan switches I got support fan speed when used for a ceiling fan, but not when used for an exhaust fan. is there any way that i can just disable presets/speeds on the exposed fan entity instead of creating a new helper?

Probably by overriding the supported_features flags via customize. Try this in your configuration.yaml:

homeassistant:
  customize:
    fan.bathroom_1:
      supported_features: 48

(fix the entity name to your entity)

That's what I was looking for, thanks!

Hey i have the Zigbee inovelli fan and im wondering if theres a way to change the amount of power going to the fan while on low mode

Ive noticed that the fan spins very very slowly and would like to give it some more power on low setting but havent seen any option

You have any ideas?

I don't, you might be better off asking in the inovelli community forum

i just wanted to share this for anyone who finds this in the future through search

the way this "48" number was determined is from:
https://github.com/home-assistant/core/blob/6974f61703261ae329b76bb2d8884fec573350cb/homeassistant/components/fan/__init__.py#L56-L61

the supported_features is a bitflags number, so you could think of the number in binary as a list of boolean options:
000001 - 1 - SET_SPEED
000010 - 2 - OSCILLATE
000100 - 4 - DIRECTION
001000 - 8 - PRESET_MODE
010000 - 16 - TURN_OFF
100000 - 32 - TURN_ON

so when you add the TURN_OFF and TURN_ON features together, you get the number 48, which is 110000 in binary
