This is a simple fan controller daemon/client that will turn on a fan at a certain CPU temperature. Written in C using the pigpio library.
Make sure you have pigpio installed on your PI.
$ git clone https://gitlab.com/TheGreatMcPain/rpi-fan-ctrl.git
$ cd rpi-fan-ctrl
$ meson build
$ cd build
$ ninja
$ sudo ninja installThe single binary acts as both daemon and client.
To start the daemon use the -d option.
Once the daemon is running you can get the status of the daemon like so.
# rpi-fan-ctrl statusThe set-upper <temp> and set-lower <temp> client commands can be used to set the daemon's current tempurature thresholds.
