I used
and
No one work

You don’t need MQTT IO to control the fan on/off
What kind of fan do you have?
Your yaml code in configuration?
You don’t need MQTT IO to control the fan on/off … .? So what i need ?
What kind of fan do you have? … 5v dc fan through transistor
Your yaml code in configuration?

hello!
i did exaclty the same but mine is not working. question is : which kind of installation do you have? HAos or Core?
could you please explain this : VCC, GNG and PWM power supply fan.
i assume you have a 3 wires fan so you have connected red wire to rpi 5v, black wire to gnd and yellow wire to gpio13 ?
I have HAos. Note that the port is not a pin number, but the actual GPIO on the Rpi.
thx for your reply. i have also HAos and the exact same code + wiring does not work for me 
Do you have your own rpi gpio integration from HACS installed?
i am not sure what you mean by my own… but i have instal the one via HACS https://github.com/thecode/ha-rpi_gpio
Same problem here.
No additional information on the Github page listed earlier in this thread.
Is GPIO add-on working for anyone?
Yes it works fine all the time. I use it to control the HA cooling fan on the Rpi4.
Update on my system. At the time of my last posting, it started working, though not sure why.
At the time of this posting, I had an issue with my system and this problem started again.
In the meantime, others have discussed this on this thread.
The solution points to new forks in the HACS GPIO integration. This one worked for me.
Also discussed here.
