Hi
When starting the service pimoroni-fanshim.service issues the following message
● pimoroni-fanshim.service - Fan Shim Service

Thanks in advance
Is this when you try to launch it manually, or when it auto starts on bootup?
It doesn’t boot by itself, and when I try to boot it manually it shows that error
This is my cheat sheet for the fan shim.
From terminal try this
git clone https://github.com/pimoroni/fanshim-python
cd fanshim-python
sudo ./install.sh
Then to install the service. (edit the on off temps to what you want etc)
This has to be run from fanshim-python/examples or it won’t work.
cd examples
sudo ./install-service.sh --on-threshold 55 --off-threshold 40 --delay 2
add
--nobutton to turn button off and
--noled to turn the LED off.
To change settings
sudo systemctl stop pimoroni-fanshim.service
sudo ./install-service.sh --on-threshold 75 --off-threshold 60 --delay 5
To disable the service
sudo systemctl stop pimoroni-fanshim.service
sudo systemctl disable pimoroni-fanshim.service
enable again
sudo systemctl enable pimoroni-fanshim.service
sudo systemctl start pimoroni-fanshim.service
I already did all that when I installed the fan, it worked fine but a month ago it stopped working, I will reinstall following your instructions
Hi
I have followed the steps above but the result has been the same:
pi@raspberryPi:~/fanshim-python $ systemctl status pimoroni-fanshim.service

Add the following to your config.txt file and reboot.
dtoverlay=gpio-fan,gpiopin=18,temp=50000
Then see if it turns on when your CPU hits 50c. If it doesn’t I’d say you have a hardware issue.
