To control those LEDs you can use the /sys api: ``` # make the GPIOs accessible echo 50 > /sys/class/gpio/export # and set direction (only need to do once) echo out > /sys/class/gpio50/direction echo out > /sys/class/gpio51/direction # turn on blue LED echo 1 > /sys/class/gpio50/value # turn off blue LED echo 0 > /sys/class/gpio50/value # turn on red LED echo 1 > /sys/class/gpio51/value # turn off red LED echo 0 > /sys/class/gpio51/value ``` ### Homeassistant support A custom MQTT Client has been written to handle the doorbell event and send it to Home assistant using MQTT.
