I’m currently waiting on the arrival of a couple of Arduino Mega2560 to update my Garage controller from the Arduino SmartShield Garage Controller project to this from @ogiewon:
Adding a few more sensors to it and then testing my hand at adding a voltage sensor.
If the voltage sensor can be integrated into the ST_Anything project, that will open up the possibility of utilizing it to monitor doorbells, third-wire smoke detectors, and anything that uses a electronic buzzer for signalling.
