Zooz ZEN23 not working with Smartthings


#1

Hi,

Looking for some suggestions. I recently bought a couple of Zooz ZEN23 switches and a SmartThings hub and am having issues getting it to work properly.

I installed the switch (replaced a regular switch, not a 3-way switch). I am able to manually turn the lights on and off using the toggle switch. I added it to SmartThings hub and my app recognizes the status of the switch when I manually turn it on and off using the toggle switch. But I am not able to control the switch using the app on my phone.

Things I have tried…

  • Removed the switch using exclusion mode and toggling down 3 times and re-adding it
  • Changed the device type form zwave relay to zwave switch,
  • Loaded the ZEN23 device handler from GitHub (removed and re-added switch)
  • Removed the switch, rebooted the hub and re-added switch
  • disabled healthcheck, ran network repair, removed and re-added switch

Nothing seems to help.

I have a V2 hub, the switch is in a plastic box, and the hub is in the same room about 12 feet from switch.

I contacted SmartThings hub and they suggested I try getting help from this forum.

Any suggestions would be appreciated.

Thanks,
-Dan

Email zooz and/or The Smartest House support. They are very helpful. I’ll tag them too @TheSmartestHouse

Thanks for the suggestion. I have been emailing back and forth with TheSmartestHouse support and they have been very responsive for sure. I have tried all their suggestions thus far with no luck. It seems many people on this forum has gotten these switches to work. So I thought I would try to see if anyone had any tips or tricks while I continue to work with TheSmartestHouse support team.

Seems bizarre that I am having issues when it sounds like so many others have it working.

Had the same problem with a Zooz dimmer a different model, I turned the power off at the breaker feeding the switch waited a minute and turned it back on and it worked.

it seems like you have tried everything that would occur to me.

I have one of these ZEN23 in 2way, using ST device type handler “Z-Wave Switch Generic” . It too is about 12 feet from the hub through one wall, serving as a master disconnect for a troublesome LIFX-bulb. Try this device type.

This ZEN23 has never failed to respond to commands, which makes it unique in my system. Note I am still using hub v1.

Since you have another, I’d swap the hardware and see if you get different results

Thanks Jason and Eric for the suggestions. I tried turning the power off at the breaker, waiting a few minutes and turning back on and also tried using the Zwave Switch Generic device type. I also tried swapping out the current switch with the second one I had. Still no success in controlling the switch via the app.

I am starting to wonder if there is an issue with my hub. I don’t have any other zwave devices paired with my ST hub. I only have 2 other Zigsbee devices which work perfect. So I think I am going to try another zwave device this weekend. Perhaps a GE Zwave switch since SmartThings support will help me troubleshoot those devices since they are officially listed on their “Products that Work with SmartThings” page.

Thanks again for the suggestions…

That is strange. You don’t have the hub or switch in a metal box or something do you? Also, the neutral wire is connected to the switch?
