Cannot add any more zwave devices

My Hubitat hub has been working fine for nearly a year. But now I cannot pair/add any more devices at all.

I have tried many different devices and none will pair.

I have tried excluding/factory reset/ new devices, etc. Nothing will pair.

I have tried shutdown and power off the hub. Rebooting of course was first.

I have tried zwave repair. Nothing. I see nodes in there that are not paired (but if I can't pair them then how will I fix them)

I have tried repairing each node seperately. One log entry shows: "Z-Wave Node 16: Repair failed node unreachable" But I can't seem to fix that

I can include/pair any Zigbee device I want. But just no Zwave devices.

So I tried to exclude an existing device. But it wouldn't exclude. So I tried resetting it to factory and then force removing the device. And when I tried to include it it just will not include. It was just working but now I cannot include any zwave device whatsoever.

I'm about to give up on Hubitat and go with some other hub. Maybe go back to Smarthings or some other hub and see what gives.

The hub I Have is Rev C-7 and platform 2.3.4.119.

Any last resort things to try before I remove every single device from the hub by force and try to re-add them all back? This will take a long time so if I have to do that I might think about using a different hub.

Have you done the zwave firmware update?
Also, have you tried to shut down the hub and pull power for 10 seconds, then boot back up?

Yes. I did the shutdown and power off and wait 30 seconds and then power back on.

I have not done a firmware update. I will try to do that. Thanks

Here's a dumb question. I see no option to upgrade the zwave radio firmware on any of the menus.

In the ZWave details section I only see 4 buttons on the top - ZWave Exclude, Repair ZWave, Z-Wave logs, and Z-Wave topology.

There is no option or button to do Firmware Upgrade. Not on mine.

Here is some more information. And I think it started happening right after I updated to version 2.3.4.119.

I started the inclusion process on a Zen34 switch. I started inclusion on the hub and then pressed the bottom switch on the zoon 6 times. I watched the light on the zooz flash blue and then it flashed green to indicate successful pairing.

But the hub never ever asked me to name the device. It just timed out.

BUT here is what happens. The device now thinks it's paired. AND I see the device node in the ZWave details. It's now listed in the Zwave details as SPECIFIC_TYPE_NOTIFICATION_SENSOR - but no named device. But it's a node and it's there.

So I tried to pair a door lock device I have that's ready for pairing. I put the Hub into inclusion mode and the device tells me that it's now paired. The hub just times out.

BUT the device is listed in the device list now. Just no name and I cannot control it.

Why would the hub now be able to include devices but not detect it and ask me to name the devices?

This all started happening when I updated to platform version 2.3.4.119

That would seem to indicate you have the latest firmware. If the Firmware update button is not on the Z-wave details page. There doesn't seem to be anywhere, that I can find anyway, that tells you the version.

If you look at this post, it shows where it should be, I don't show the update button either, but I have updated mine. So I assume that is why mine doesn't show it.

More weird things.. I put my hub into exclusion mode and I press the bottom button on the zen34 switch to being exclusion and the zooz device flashes the light to tell me that it has been successfully excluded but the hub times out.

So there is proper operation of the radios as far as I can tell. But the hub doesn't report it to me.

Doesn't really sound like a database issue, but you could try a soft reset.

And if that doesn't help there's Restore Previous Version in the diagnostic Tool.

Alright. I'll create some backups and try that. Thanks

Just did the restore after a soft reset. That doesn't seem to have worked either.

I saw a 'memory low' warning when I was updating my hub a few days ago. That seems to be when this all started. Never saw that error again. Went away after reboot. But would that be a clue?

I only have 7 devices on the hub now. Should I wipe the hub and just start over with it all? I hate to do that and then not be able to get anything on the hub at all. But then if that happens I guess I'll try to turn it in on warranty. If there is any warranty left.

It is very strange that you can see the device in Zwave section, but it doesn't show in the device listing.

I wouldn't wipe the hub. Maybe with the guidance of support the Zwave radio, but certainly not the whole thing.

If you can wait, I would see if support would like to look at this. I don't know if engineering logs would show anything, or not?

@bobbyD is this something that you could possibly look at?

It's very strange. But it appears the z-wave radio is operating fine. The actual devices think they are paired and they appear in the z-wave radio section. Just not in the device list and the including process does not ask me for a device name after the device tells me it's included.

There is something really weird going on in this hub and it's not making me feel like I want to add the 50 or so devices to it only to have this problem at some point down the road.

I'd almost feel better buying a new hub and starting over. But I guess I can wait and see. I'm done with it for the night. I spent all afternoon on it.

Where was this memory low alert? If it was from the Z-Wave radio, then likely some stranded devices are misbehaving, which can lead to radio running out of bandwidth.

Based on what you shared thus far, it is not clear how you ended up with only 7 devices? Have you forced remove them? That would explain why they are not listed on Devices page but they are present on Z-Wave Details page. Force removing devices effectively creates ghosts, which could make inclusion/exclusion difficult, if not impossible.

If you didn't check the Z-Wave Troubleshooting document, here is a link to it that may give you some ideas what to look for: How to Troubleshoot Z-Wave | Hubitat Documentation

Last but not least, you can send me a private message and we could look at your hub's engineering logs to see if we can figure out what's going on (assuming your hub is connected to the cloud).

Can you post a screenshot of your z-wave details page?

I found out how I ended up with the ghost nodes.

When I was doing an inclusion, the devices were reporting that they were included just fine. But the UI in Hubitat would not recognize the inclusion and would time out - so it would not ask me for the name I wanted to give the device and what room I wanted.

I have since removed the ghost nodes. I did this by doing an exclude and then initiating an exclude on the devices. That worked. I do not have any ghost nodes in Hubitat any more.

But it won't let me include devices. They just end up as ghost devices. I cannot get the UI to recognize that a pairing occured.

Here are the details now. I removed the ghost nodes.

The third one down (Master bathroom mirror lights), too?

What model are your Inovellis?

9.6kbps on Z-Wave devices is cause for great concern. Either you still have misbehaving devices or you need repeaters. That might be why inclusion times out too.

I have lots of old Inovellis and some reds. But that one is an older Inovelli. By old I mean less than 2 years old or so.
