fan-shim on rpi4

sudo pip install fanshim
git clone https://github.com/pimoroni/fanshim-python
cd fanshim-python/examples

If you need to change the threshold, hysteresis or delay you can add them as arguments to the installer:

sudo ./install-service.sh --on-threshold 65 --off-threshold 55 --delay 2

To enable CPU-frequency based control:

sudo ./install-service.sh --on-threshold 65 --off-threshold 55 --delay 2 --preempt
