SmartThings for security--how to add cellular backup?

[vjv (Dumb)]

Here is what I did, works great.

Cellular backup?

I looked multiple ideas, I ended doing my own: I have all my internet devices with UPS battery backups, this includes my security cameras, Smartthings, cable modem, wifi router. Probably I will get a Tesla power wall in the future lol, I have about 10 UPS battery backups. For the power loss notification, I have the Aeotec energy meter, I setup a piston in webcore to monitor the voltage in my home, if it is less than 90v the battery backups will be using battery so webcore will send me a custom notification to my cell phone. This will be corrected in the future, I have plans to get a automated power generator with its transfer switch. I have a generator but I must connect it. Not the best if someone cuts your power too, but I will have time to see over my cameras before everything dies. F…
