I have a first world problem that I'd like to address. Sometimes I don't notice the fact that the LED on the PID has gone off, indicating that the reservoir is empty. So the machine cools down, and when I return a couple of hours later with high hopes of another coffee, the machine is cold. I'd like to put in some sort of alert to make it more obvious. Either a bright LED that comes on somewhere, or a small noise. Can anyone think of a way to use the existing sensor, which is triggered by a magnet, to trigger some other alert as well? Or should I be thinking of putting in a separate sensor? I've put a few pictures in to jog the memory of anyone who has an idea here! (I've also thought of playing with this project to learn some other stuff, like linking it to a wifi enabled device, maybe something by Sonoff or someone, that would then send a message to my phone, or make Alexa play a song. Overkill, naturally, but it would be a project that would teach me some stuff that may get used elsewhere!) Thanks for any ideas!
