    I contacted Z-Wave directly on the compatibility question. If they have been tested and verified by Z-Wave, the product must meet the standard to be openly compatible. If you hear otherwise, please forward these comments to

    This Z-Wave product is ONLY compatible with GE Simon and 2Gig control systems! If you have another Z-Wave controller, HomeWercs has confirmed that this module is NOT compatible with other systems. So much for an open Z-Wave system, I am very disappointed!

    READ THIS CAREFULLY PLEASE! There is a difference between a Zwave and WiFi network. The two are NOT interchangeable, and if you are trying to connect to a home wifi network with a router as most of us are you need a DIFFERENT Usnap module, available from This module will not work unless you have another Zwave controller somewhere in your home. I learned the hard way. If you're even a little confused, check in with the manufacturer first - their tech support is really first rate.
