Maybe you do have pigpiod installed and you still get that error. That happened to me. I found the problem and the solución:

PROBLEM: I don’t know why, but when pigpiod is run with the parameter “-l” (small L), the pwm_fan_control.py script does not work.

SOLUTION: In Raspbian the script is run according to this file: /etc/systemd/system/multi-user.target.wants/pigpiod.service In that file, DELETE THE “-l” PARAMETER WHEN RUNNING pigpiod, so it should look like this: ExecStart=/usr/bin/pigpiod

Tested and working OK on Raspbian version 11 bullseye
