Z-Wave manages your automations. Range Extender 7 manages Z-Wave. 
 
Z-Wave doesn’t rely on expensive cable laying. It’s wireless. But that means that, just like Wi-Fi, there are areas where the wireless signal may not be optimal. Range Extender 7 fixes wireless weakspots. Install it in the appropriate place, sync it with your gateway, and Range Extender 7 will start optimally relaying and amplifying Z-Wave. Dead spots become a thing of the past.
