The hot tub is on a separate power circuit and sometimes it will trip the breaker. When that happens, if I don't catch it in time, the pipes will freeze and burst, resulting in a very expensive repair.

I have a sump pump in my crawl and obviously ensuring the circuit is on is very important. I use a combination of a contact sensor, 5VDC relay, and a usb plug to monitor the power. If the GFI trips or power loss, I get notified. You can read more here:

Power Circuit Monitoring for Power Loss

In a few weeks I am having a sump pump installed in my crawl space because of on going water issues. I have a receptacle in the area of the pump that is tied into a GFIC outlet. For obvious reasons I want to be notified if this outlet ever loses power. I saw @Cobra and @Navat604 old posts on the ST community Curious if these solutions are still working or if there are better ideas. @Navat604 what relay did you use in your contact sensor? It is very small and appears like you have it in…

Another option could be using a CT clamp hooked up to an ESP8266 board using @ogiewon’s HubDuino libraries and monitor voltage that way. I’ve got the part to set this up to monitor my hot water heater circulation pump, I just haven’t had time to set things up yet. This solution is MUCH cheaper than Aeotec device mentioned above.
