  Hi All, I have written a small python script to send and receive MQTT messages. Messages are send when inputs on the UniPi are changed, and UniPi outputs are changes if MQTT messages are received. More information here; https://github.com/matthijsberg/unipi-mqtt/ Don't expect clean of fancy coding, just an amateur that build this for his own purpose, integrating UniPi into my Home Assistant setup.

  @heikkim Hello, to enable wifi you should enable the interface in /boot/boot.cmd by commenting the followin lines (add a # at the beginning) fdt set /soc/mmc@01c10000/bcrmf@1 status "disabled" fdt set /soc/mmc@01c10000 status "disabled" Then run mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr and reboot. Does it work?
