Hello world. I have been getting into WebCore - what an amazingly flexible app!
Today I am looking for a hardware suggestion. I have an old electric clothes dryer (North America) with a very loud 110V AC intermittent buzzer/notifier that the drying is finished. The idea is to disconnect this buzzer and connect an inexpensive AC Voltage sensor or switch to trigger a more gentle notification through Alexa or similar.
In a nutshell, if voltage goes from 0 to 120V, trigger a notification. Can I just wire a plug or switch and use a piston to monitor its online/offline status? Any examples?
