ZOOZ700 Series Z-Wave Long Range Double Relay ZEN52 | Control 2 Lights Individually, Signal Repeater | Works with SmartThings, Hubitat, and Home Assistant (JS) | Z-Wave Hub Required (Sold Separately)

I installed this Mar/2025 smart home device using the SmartThings hub v2. I have nine smoke detectors in my house.On the first link, I pressed the button three times to connect the device to my hub. However, I encountered an issue because the hub connected but didn’t function correctly. After researching, I discovered that I needed to install the Zooz driver first on my hub.When I attempted to update the driver in the hub, I couldn’t switch to the newly installed Zooz driver. Consequently, I had to put the device in exclusion mode and remove it from the hub. Next, I re-added the Zooz relay, and the device connected immediately with the correct driver.The relay produces no noise and fits perfectly in a 1-gang box, even though the box contains three Romex wires.

I installed this inside a metal junction box to control a light at the bottom of the basement stairs. Previously this had been controlled by a standard motion sensor with timer switch at the top of the stairs, but I wanted another motion sensor elsewhere in the basement so the light would stay on while someone was down there. I paired this with two Zooz "Q" motion sensors, all programmed through a Universal Devices EISY hub.I was initially skeptical that the relay would get the Z-wave signal inside the steel electrical box, but it does so reliably.

This was relatively easy to install, but I had trouble pairing it. Support answered my question very quickly. I needed to push the button faster to get to pairing mode. Once I got through that, the switch works great. It is nice that Zooz has custom edge drivers for using this on Smartthings.

Works great with Home Assistant

The media could not be loaded. Got this relay to control my kitchen LED converted tube lights. Installed it right up there next to kights since my wall switches don't have neutral wire (1950's building).Installation was a breeze, instructions are super clear. Pairing to my SmartThings hub took some time. Scanning just wouldn't pick them up Had to reset the relay twice, but after my hub has found it it was super easy to control. It installs as three separate switches, one for each output + master controller switch. If you go to the settings of the Zooz controller and set it to turn on after power loss, you can use a regular wall switch to turn it on/off with 1 second delay.

Been using Zooz products since I started the task of automating my home, the light automation is always a good starting point. I wanted to maintain my current “dumb” switches and found this option. The pair is easy and works with home assistant (You need a zwave hub) It seems to be reliable. I’m happy with this product.The only observation is that you’ll need to change an option for the external switch “toggle” the light instead of fixed actions, and in my case there is another option that add a delay to detect multiple clicks, I hate that delay, but is configurable.

Let's start with the positives:* This thing is tiny. It packs two switch inputs and two relays where other manufacturers fit one* The price is about 40% less than other Z-Wave double switches* Lots of options for setup in Home Assistant, though this is a double-edged sword. Keep reading.The negatives:* The wimpy 5A relays put some pretty serious restrictions on where you can use this. A ceiling fan comes close to maxing out the relay rating. Definitely do not connect this thing to a switched outlet or anywhere else you can't guarantee a current draw under 5A. This limitation should be more clearly marked on the packaging. For example, you should definitely not use these to control a switched outlet. Someone might plug in a high current device in that outlet and cause a major problem.* Makes a little bit of a humming/buzzing noise. You won't hear it once the device is squirreled away inside a wall box, but I could definitely hear all three units I bought when I had them hooked up in the open (with all exposed wiring covered in Wago connectors) for pairing.* The default switch setup is a little confusing out of the box. I suspect the most common use for these, by a wide margin, is connecting them to existing light toggle switches. The switch inputs on all three of my units were not set that way by default. I was initially very confused when I got the switches hooked up, flipped the lights on with the physical switch, flipped them off with Home Assistant, and then had to hit the switch twice to get them to turn on again. I had to go into the device options in Home Assistant to get the switch inputs set as toggles (I don't remember what the initial setting was). I have lots of Wi-Fi, Zigbee, and Z-Wave smart switches and these are the only ones that weren't set up for toggle inputs by default. It is a minor issue, but I bet the manufacturer gets a lot of these things returned by confused customers that don't have patience for tinkering.Update: I have installed three units inside wall boxes in my house and all of them have had incidents where they completely stop working until I turn off the circuit breaker and turn it back on. When this happens the unit is unresponsive in Home Assistant AND the physical switch stops working. This is completely unacceptable.
