We had a pretty wet fall here, and I setup sense to warn me if my sump pump stays on for more than a couple minutes.
Bingo! Seems sometimes the float switch isn’t turning off when the water level drops. Sense notifies me, and I can turn it off (plugged into a tplink hs110) and flick it back on when I get a chance to check on it. Alternatively, if my leak sensor (home assistant not sense) goes off, I know the sump isn’t functioning. But seeing it overheat lets me intervene and prolong its life some until I can get around to replacing it!
