AVOID Smart Monkey SM1 at all costs and get the Vivint Smart Drive SM2 instead !!!
Smart Monkey SM1 (Version One) does not work with many Vivint central systems. Smart Monkey made the SM 1 version and it went out of business. The SM1 that I bought was only worth being a paperweight before I tossed it...it could not even serve as a hard drive. Instead, I bought a Vivint Smart Drive SM2 (on Ebay) to ensure compatibility with my Vivint system and it works perfectly!
