Hi everyone, just starting out with ST. I have a full size freezer in my garage that is connected to a GFI outlet that will occasionally cut out due to storms, etc. I have a traditional freezer alarm installed, but I’d like to know immediately if the outlet trips, without waiting for the freezer t…

Interestingly, the SmartThings Motion Sensor can be used to do this. It is capable of being battery or AC powered. I don’t think there is an app that currently exploits this functionality though. Do you have a motion sensor? I’ll see what I can do on the App side.

Or just connect the freezer to an external outlet ( https://shop.smartthings.com/#/products/ge-outdoor-plug-in-module ). You should be able to create a custom device type with some polling code to determine if it goes off and their either create an app or, even easier, an IFTTT recipe to alert you if…

Here’s an app that will do just what your asking for using the motion detector as an AC power detector. Let me know if it works for you. Twack /** * * Power is Out * * Alert me of an ac power loss on motion detector by detecting change from * powered to battery. * * Author: todd@wackfor…

Hey @twack , that’s a really cool trick. Thanks for sharing!

But in order for smartthings to work the hub will have to also have power and have an internet connection. So if your power goes out in your whole house due to a storm then you will need another solution.

@njm5785 , you should put your modem, router and ST hub on a beefy UPS. If you’re using ST as some sort of security system, you should also get a router with automatic cellular network failover.

@florianz They have routers that failover to cellular network? Do you know of a good one? This is a pretty good idea and most the time will work if you have all of these measures in place. Then not only could you get a notification if a unit like a freezer was off but if your power is all off in yo…

@njm5785 , check out the CradlePoint routers, Peplink Balance 20 (or 30), Pepwave Surf, or ZyXEL ZWUSG50 to name a few. Not sure, which one is the best. The CradlePoint devices are more consumer oriented and features integrated WiFi. If you’re like me and prefer to use a different WiFi bridge, you mi…

In my particular case, it’s a case of GFI’s being too sensitive in some instances, versus losing power to the whole house. Great recommendation on the UPS and router fallover, as I should have this for my VOIP anyway.

Have you successfully come up with a solution? I have the same problem and and looking for a solution to monitor when the GFI plug trips.

This is awesome! Power is Out based on state of v1 Motion Sensor
