Thank you ! Definitely something I need to check out... Circuit has only died once since I have had the tank running (5 months now), but of course that happened to be a day I was out of the house for several hours....This is what I use and it works great. It sends you both a text message and email alerting you the power went out on that outlet. Although, if you want it to work for when the whole house loses power, then you need a UPS backup for your WiFi and Internet.
