Having just suffered an inch of water in our basement I’m trying to design some safeguards. This time around the cause of the flood was my sump pumps tripping in the middle or the night and the battery backup running out of power, all whilst we were asleep. The pumps (2 x 9A) are now on a dedicated 20A circuit, rather than sharing a 15A breaker with the rest of the basement! I have a FibaroHome Flood detector, and sure enough I had a ‘leak detected’ alert on my phone at 1.15am, but it didn’t wake us. My immediate fix is to install a smart switch in our bedroom and create a trigger to turn the light on if a leak is detected.” Next step is to get a plug in power outage alert, again in our bedroom, so we lose all power it will wake us and I can get my generator running. The final step is something to alert us of an issue when we’re away from the house. With a couple of APC BGE90M power supplies I can keep my network running for a couple of hours after a power outage, but I would need something to send me an alert that the power is out. Anybody got any ideas? I was thinking about one of the plug in switches that offers power monitoring, but they would fail as soon as the power goes out, and anything plugged into a UPS would not know the power had gone out, so it needs to be a device with a battery backup that can trigger an automation when mains power is lost!?!?
