I purchased 2 of these from Amazon and got a recall notice via email this morning instructing me to contact Vivint to get it replaced. Units effected start within the serial number range 1115-1440. There is an issue with devices connected to them catching on fire.
I called Vivint and they said “Sorry… you are not a Vivint customer. Call Amazon.” I called Amazon and they offered to put me in contact with the original seller to ask for a refund. I may be out $60 for the 2 units I have. If you have these units you may run into the same problem. Mine have worked very well but now I am going to remove them from my setup just in case.
