Hello good day

Does anyone have this module working in HA ?
Rgb cooling hat: http://www.yahboom.net/study/RGB_Cooling_HAT
I have try it with this info:Controlling cooling fan for Raspberry Pi 4
But the fan won’t do anything.
I added this to my config:

  • platform: rpi_gpio
    ports:
    18: RPI Cooling Fan
    Also the Raspberry Gpio installed .
    I did some measurements but I can’t find which pin controls the fan.
    I hope someone can help me, thanks in advance

Hello weske2000,

That is quite an old post so I am not surprised that does not work. rpi_gpio there is likely the stuff that was removed from core.
I am thinking that there is now one or more custom integrations to help with those functions available on GitHub thru HACS. You would have to search for them using HACS, I don’t not personally use a PI and do not know for certain.
