I’m having problems pairing new devices with my Zooz ZST39 800LR stick. I’d like to revert to my Zooz ZST10 stick to see if these pairing problems persist. All my devices are paired in non-LR mode, so this should be straightforward, in theory.
I am struggling with the backup/restore user interface in Z-Wave JS UI.
It appears that there are only options to schedule backups with cron. I don’t see a way to initiate an immediate backup of both the store and controller NVM, or to restore them. I checked the docs, but also didn’t find it.
You’re in the settings. To make a an NVM backup and restore, go to the control panel → blue button (FAB) → Advanced Actions, then the NVM management options will be there.
Is this NVM backup you pointed out the ONLY think you need to do before switching controllers, say, the Zooz 700 controller for the Zooz 800 controller?
I backed up 3 things - the settings, the nodes, and the NVM from 800LR controller. And was able to restore them onto the 700 series controller.
Everything is looking good, except Node 1 is still listed as being a ZST39 rather than ZST10.
Unfortunately, I’m still having the same problem pairing devices. I have two First alert Zcombo smoke/CO alarm. They were delivered today brand new in box with recent dates (actually, I got 4, but only opened 2). I cannot include either of them, manually or through SmartStart, with either the 700 or 800LR sticks. I bought one Zcombo a few weeks ago and it paired fine. There has been a few Z-wave JS UI updates since, though. I’m not sure if something might have regressed. I’ll try restoring the older add-on to see if it makes any difference.
Thanks. Actually, the issue came from the string I manually input for node 1 with the 800 stick.
The documented procedure for excluding and including is exactly the same - press and hold the button while inserting the battery tray, and then release the button. But it always fails to include, manually or through SmartStart.
So, one of them finally included, but without security. HA reported a timeout. The exclusion procedure does not work. I had to manually remove the node in the UI. I could not get it to include again with security.
The used one I got a couple weeks ago from ebay had no issues and was included with security through Smartstart right away on my ZST39 stick. That unit was delivered on Feb 8 and included the same day.
So, I restored the Z-Wave JS UI add-on from a Feb 9 backup, but using the ZST10 now. I am still not able to include these 2 new units.
I then reset the ZST10 stick to factory settings. I still cannot include those 2 new ZCOMBO.
I took the unit that had been paired successfully two weeks ago with the ZST39. It couldn’t be paired with the ZST10 now.
I restored last night’s backup and switched back to the ZST39 stick. The previously working unit still showed as paired and green. I initiated a manual alarm test, and it reported state properly in HA.
I tried to exclude it, but couldn’t. HA just times out during exclusion. Just like it does for inclusion for the new units. Not sure what else I can do to get the new units working.
Sometimes devices are still included in a test network when they come from the factory, so they need to be excluded before they can be included again.

Possibly network issues. Try these steps, especially USB extension cable.
Thanks. I already have my ZST39 stick on an extension cable. It is elevated and taped to a drywall with pretty much nothing else on it.
It’s not possible to put it in a central location. It’s in the front room on the ground floor, in a 2.5 story home. The house is not wired for ethernet, and cannot be, and I don’t want to run Home assistant on Wifi.
There is computer in the same room as the stick, but at least 6ft away. There are 57 working Z-wave nodes in the house other than the controller.
I can certainly believe there is interference. I have had some unexplainable things happen to my Wifi and Yolink devices recently that sound like they could be attributable to interference. But I haven’t been able to put my finger on it.
How do I view the RSSI in Z-wave JS UI ? I couldn’t find the data.
BTW, I tried to pair the Zcombo at distances between 3 and 10ft, with no difference. It looks like neither exclusion nor inclusion are working. Maybe there is a factory reset procedure, but it’s not documented.
One thing I did see when one unit paired insecurely was that it was at firmware revision 11.0, the same version as my other unit that is still paired successfully with S2 Auth.
I think the theory that it is interference is correct. I have 2 more devices from other brands (Minoston, Zooz) that I am also unable to include, but was able to in the past.
I have 3 ZCombo that I could add with no problem. And 4 that I just could not, no matter what I tried. They were a more recent batch from First Alert, from 2024, vs the others being from 2022-2023. All 7 were bought on ebay. I had to return the most recent ones as I just had no luck with HA.
I’d take a look at how saturated your zwave network is. Too much traffic causes all sorts of issues.
Look at the RX stats by device (these get reset when zwavejs is restarted), so restart then look at in an hour and it should be easy to find the chattiest devices.
Thanks. I can see the statistics when clicking on each device, and then statistics. Is there a way to get a table with the statistics for all devices ?
Also, I still haven’t figured out where the RSSI is listed in the GUI. I would appreciate your help in locating it.
