>* a vibration sensor combined with a tiny hall sensor on the door of the washer/dryer to notify me when laundry is done (trying to measure power usage on 220v wiring was looking to be more annoyance than it was worth, so i went a different route!)
Your option was likely much less expensive, but aeotec does make a clamp-on energy sensor[0]. It's made for reading your whole-home energy but it should work for your purposes. But like I said, your solution was likely much cheaper (these are about $99).

- Klathmon 8y agoI thought about that, and like you said it was pretty expensive, plus it would require me to cut the power line for the dryer to pull one of the lines out. And then I was back at square 1 for the washer, which turns out uses little enough energy in a lot of cases to be hard to tell when it's "done" vs when it's just pausing between cycles or swapping water out. I also wanted to have the notifications continue until you actually empty it, and that required a door sensor anyway! I really want to get one of those for the oven though, my wife tends to worry that she left the oven on (she never has!) and something like this connected to it might help ease that worry. And I REALLY don't want to do anything invasive to the oven, as that's one thing that i REALLY do not want accidentally turning on or shorting out.
