+# Fan control daemon for devterm cm4(rpi os)
+ 
+## Install
+
+**Devterm is pre-installed this package, so devterm cm4 users do not need to repeat the installation steps**
+
+```
+wget -O - https://raw.githubusercontent.com/clockworkpi/apt/main/debian/KEY.gpg | sudo apt-key add -
+echo "deb https://raw.githubusercontent.com/clockworkpi/apt/main/debian/ stable main" | sudo tee -a /etc/apt/sources.list.d/clockworkpi.list
+
+sudo apt update && apt install -y devterm-fan-temp-daemon-cm4
+```
+
+## Change the threshold temperature
+
+Edit `/usr/local/bin/temp_fan_daemon.py`
+
+line starts with `MAX_TEMP=80`
+
+For devterm cm4(rpi os) the  recommended MAX_TEMP is in range 60-80 
+
+then restart systemd service to take effect
+
+`sudo systemctl restart devterm-fan-temp-daemon`
+
+## How to control the fan from GPIO
+
+``` start the fan
+sudo gpio mode 17 out
+sudo gpio write 17 1
+```
+
+```stop the fan
+sudo gpio mode 17 out
+sudo gpio write 17 0
+```
