I purchased 2 of the ZEN57 small relays. They were both going into the hardwired connection of towel warmers. I’ve been successful getting 1 paired and fully operational in home assistant. Unfortunately, the 2nd unit will not pair with home assistant and my zooz z-wave 800 dongle. There is no switch connected to this. At this point, I’ve attempted to reset the bugger a few times and am still unable to get a successful pairing with my 800LR zooz zwave dongle. I’m not even sure it’s resetting.
The device has power and a slow blinking green LED.
When I initially got it into pairing mode and provisioned on the z-wave network, it never completed. I was hoping to test the relay by ensuring I could reset the device before trying to return it.
I tried to exclude it from the network by doing the pairing steps again. While entering the hub’s exclusion mode, I press the device button until I get a fast blinking LED light. It fast blinks for a short bit then goes solid red for 2 counts (I believe it is considered 2 counts), then back to slow blinking. The node is not excluded from the zwave network.
Next step appears to be resetting the device so I can exclude and attempt to re add the device.
When resetting the device with 1 press followed by holding down the button for 15sec, it returns the solid red LED then returns to green slow blink. Following this, I attempted to re-add the device and it still will not complete the interview.
System is using the zooz zwave 800LR dongle and home assistant. I’ve successfully although not always seamlessly populated my zwave network with 24 devices. Several zooz switches and dimmers along with other devices.
Being that one of my relays is setup and working but is located even further than this one from the hub, I don’t believe range should be an issue for where this 2nd unit is located.
Hello, and Welcome to the forum!
A couple of questions:
In Home Assistant are you using ZWave JS or ZWave JS UI?
How are you joining this to Home Assistant?
By scanning the smartstart code and letting it auto-add,
OR
By entering inclusion mode in ZWave JS/UI and then pressing the z-wave button on the ZEN57 three times?
If using the smartstart code, are you attempting ZWave LR or ZWave mesh?
If using the manual inclusion mode (not scanning smartstart) and pressing the z-wave button 3 times, does the ZEN57 react to the 3 presses by the LED flashing faster?
From there, do you ever see the prompt to enter the DSK code in HA? if so, after entering the DSK code, what message do you get back in HA? (Added or not and what level of encryption)?
Lastly, is the ZEN57 itself inside a metal electrical box or other metal enclosure?
That data will give more clues for us to assist.
Thank you
I had an epiphany last night identifying the problem and then I read your response…so, I’ll answer all your questions:
Zwave JS
Joining by Start Inclusion, Scan the Code, and also press the button (still mostly a newbie and this was one step that I wasn’t sure was necessary but incorporated it when the 1st attempt to be identified failed)
Using LR not mesh (big shop+house building)
I do get the fast blinking green LED consistently when doing the 3-button press
It would be added (not sure about the encryption level) but would report as still being interviewed and never complete.
Epiphany is this towel warmer has a metal cover plate (as does my working ZEN57+towel warmer setup). Although one setup is working, I thought that might be just enough to create communication problems with this location. When I mentioned that to my husband who did all the electrical work in this place, he mentioned it actually has a metal electrical box not a plastic one like the working setup. I had no idea and didn’t even pay attention when troubleshooting. He believes we can swap the box out but I need to pick up a remodel box and then we’ll start the process over.
I’ll update this thread once we’ve reworked the box situation. Thank you for the questions and inspiration. If there’s anything you picked up that I could be doing differently, let me know.
That all makes sense. I’ve had some similar challenges with the zen58 (the 57’s low voltage cousin) in metal boxes as well. In some cases I got it to join but after some time it would go non responsive. So I moved it to a plastic box inside the house and things were good. I also have one running in a metal box in mesh mode with another node very close that so far is working well. There are a ton of influencing factors of course.
It would be great if these little relays had an external antenna to route outside the box.
I suppose to test you could leave the cover off the metal box and pull the 57 out into the air and see if things join and work better. That may eliminate other variables.
