Zooz ZEN51 Z-Wave 700 Series Long Range Smart Relay | Installs Behind Wall or Light Switch | Compatible with SmartThings, Hubitat and Home Assistant

Easy to install and has worked no problem at all.

Works well with Home Assistant and easy to wire up. Will be buying more!

I purchased two of these to install directly in my 3d printers so that I could control power on/off through Home Assitant. Worked perfectly, setup with HA was straightforward and worked with the quick start code.

I had the ubiquitous Linear FS20Z-1 Z-Wave contact fixture module installed in my front wall for many years to automate the lights on top of the wall. After about ten years the module went kaput and seems to no longer be available. The Zooz 700 Series Z-Wave Plus Smart Relay does everything the FS20Z-1 did in a much smaller package, making it far easier to embed in the outlet box without working too hard to fit in all the wires. While this module is not rated for outdoor use the box is weather-insulated, and I further wrapped the Smart Relay in a sandwich bag sealed with duct tape, so I'm quite confident no moisture will enter. Temperatures are mild enough here in Silicon Valley that it should also almost always be within the operating range (32F - 104F). It paired easily with my SmartThings hub (V2) and works as expected. Note that I'm not using the switch contact, I'm only controlling it via Z-Wave, so I can't comment on that feature, but I have no reason to think it wouldn't work as expected.

I am a technical tinker, and wanted to be able to have my interior garage lights turn on when the garage doors are opened while it’s dark outside. I used rules on my Smartthings hub to trigger the lights when it sees my garage door sensors open. You MUST have a good understanding of electrical wiring and 3-way switching to assure this is installed correctly. Important things to know: 1.) the 3-way switches will continue to work regardless of which state this relay is in, which is great! I also have a Zoos relay on my garage doors that monitors door status switches on each door, and momentarily activates the relays independently to open/close each door via commands with an echo Dot I keep in the garage (located far away from windows and doors to prevent a thief from opening the doors from outside the garage). 2.) I needed to take this down near my hub to initially add it to the zwave network. 3.) it’s very small and fit inside of the switch box. 4.) the average person without technical knowledge would probably not be able to install this.
