We have covered plenty of Z-Wave compatible smart devices here in the past. The VeraLite Z-Wave Multi Device Controller is a useful tool that lets you control individual devices or groups of devices easily. The controller has a built-in battery pack and is easy to use. Just plug it into an open port in your WiFi router, and you are ready to control things around your home. The VeraLite Z-Wave will be available for under $130 at this time.
