I’m new to HA and I’m wondering if it’s possible to set up another Raspberry with camera pointing to the house heating system’s indicator leds which tell the state of system. A bright green led is always on if everything is ok and it turns red if there is a fault in the system.
I would like to get a notification if the led turns to red.
I have one extra Pi Zero W and a camera module. My HA is running on RPi 3 B.
