Zooz Heavy Duty Light Switch ZEN75 Frequently Asked Questions
NOTE: If you don't see your Z-Wave controller on the list above, please contact us before you purchase this product.
Before installing, make sure the load does not exceed 1800W for incandescent lights, 600W for LED's, or 15A for resistive load (read more about supported loads here).
Check your wiring first to confirm that you have all the following wires present in your gang box: load (most often black), line (most often black), neutral (most often white), and ground (most often green).
If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.

How to include the Zooz Heavy Duty switch to your smart home network?
1. Bring your Z-Wave gateway hub or controller as close to the switch as possible
2. Put your Z-Wave controller in inclusion/pairing mode
3. Scan the SmartStart QR code on the front metal plate of the switch or tap the upper paddle of the switch 3 times quickly to finalize the inclusion process manually
4. A new on/off switch should appear on your controller's device list
NOTE: Use a dedicated diagram from the manual to wire the switch in a 3-way setting with a regular electrical switch if you are looking to control one light with 2 or 3 switches.
There is no rocker on the switch but you need to press the top or bottom depending on if you want it on or off
After some research, decided to switch to Z-wave and Zooz after yet another of my Tuyu switches failed. Easy to set up, well-made, and works perfectly with my HA based smart home.
I wish I had heard of Zooz before I populated my house with useless so called smart switches. The Zooz were very easy to adopt and install.
They are working great with my ballast fluorescent tubes lights in my garage. I'm planning on using these for my heat tape installs as well. Just be sure to keep an eye on wattage.
I did run into a bit of trouble. I was not able to get multiple ZEN75 to join using Mesh. It worked fine using ZWLR. I have a ZEN77 and a ZEN76 at the same location which were able to join my network using SmartStart and Mesh. So I expect there is likely some sort of bug preventing this from working. I'm not planning on using associations so this will be okay for me.
Be aware the pigtails take up a ton of space, so if you don't have a deep box I wish you good luck getting it fit. The stranded wire fit into wagos.
Once installed they look and behave like the rest of my zooz switches.
Being able to swap out our dumb switches for the heavy duty switches for things like Fans and outlets has opened up a lot of automation opportunities. I had an electrician install them and they said they were easy to install and well documented. Will definitely be buying other Zooz switches.
