Hi all!
I am very new to Raspberry Pi and Home Assistant, I have looked for a similar topic in the community forum but wasn’t able to find a proper solution.
Home Assistanto OS is installed on my Raspberry Pi4 8GB, which came with a very nice 5V Noctua 40mm fan wit PWM control. Now, I have connected the fan to 5VDC and GND pins and it runs all the time very quietly, so I could even leave it as it is 
Is there a way to control fan speed with PWM directly from HA?
Thanks in advance
Stefano
