When I installed sense I noticed an unknown 600w load from 6am to noon every day. I have an aerobic septic system that the irrigation spray pump was on a timer with a shutoff float switch. After some basic testing I realized that the pump was on for the ENTIRE TIME it was set to even after it had emptied the tank. About 5 hours more than it should. I could use Sense to determine the optimal time to change the timer to empty the tank while minimizing the ‘pumping on empty’ waste.
