I just put some magnetic switches on the cabinet doors. I'm using them to shut off the ATO when I am working on the tank so it doesn't try to top off when I am doing a water change. The program for that is fine.
I want to make a program that will alert me if one of the switches goes bad or maybe the door doesn't close all the way. Basically, if SWX2_1 is open for 180 minutes, send an email alert. How can I write this in the emailalm section?
