ZOOZ 700 Series Z-Wave Long Range Smart Relay ZEN51 | Installs Behind Wall Switch Or at The Light | Compatible with SmartThings, Hubitat, and Home Assistant | Z-Wave Hub Required (Sold Separately)

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

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 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.

Easy to install and has worked no problem at all.

The "Zooz 700 Series Z-Wave Plus Smart Relay ZEN51" works great in non-dimming lighting applications. Like they said, you can install it at the light fixture, which is exactly what I did, there was no neutral at the switch location. It is quite tiny but nevertheless you'll want to use Wago connectors--BTW cheaper in bulk right here on Amazon.What made it "better than advertised" is that the switch controlling the light fixture still works properly. Automation will turn the light on or off regardless of the original wall switch, but the switch can still change the fixture on or off. If the switch is off and the light was turned on by automation, flipping the switch on doesn't change the light; it's not illogical.Of course you can setup annoying automation to change the light to a predetermined state whenever the switch is flipped, I suppose that's good for April Fools or whatever. For us, it's a very easy one-time override for the automation schedule.Our Z-Wave hub setup is Home Assistant running on a Raspberry Pi 4 with an Aeotec Z-Stick 7 Plus. This open source hub but not complicated, I imagine the relay works easily with other Z-Wave hubs. Adding the ZEN51 required only a Z-Wave JS inclusion, it was instantly detected.My big problem now is that I need to resist buying a bunch of these causing automation overload!

Used this to automate the light of my range hood. We kept forgetting to turn it off, so now it does it on its own!All of my zwave devices come from ZOOZ and I couldn't be any happier.
