As a data point here, the people from Ting electrical monitors should really contact me. I used their app for a few days and then built something way cooler off of it and managed to run down what was causing our high electrical usage (the well pump serving an out of control ice maker). You can’t do this at any fine-grained level, but the well pump’s electrical draw was very recognizable by just having the data logged to SQLite in real time from the Ting api and then telling Claude when the pump went on and off.
