LEDs

The camera has a dual color LED (red/blue) connected to GPIO's 50 and 51. 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. Project can be found here: lscdoorbellmqtt
