My hub is a C-7, running version 1.3.9.143.
Today automations started failing. Unsure what was going on and because I was working (from home) I went to Settings/Reboot hub. That did not seem to help.
This evening I discovered that NONE of my Zwave devices are listed in Settings/Z-Wave Details. The region is correctly set.
Following instructions on other posts, I did the following:
Three times, shut down the HE from Settings, then unplugged it from the wall and unplugged the ethernet for longer than 15 seconds (1st time) then 120 seconds (2nd time), then a few hours (3rd time). It restarted with the blue light and the light is now green. However, I still have no Zwave devices listed, and none respond.
In Settings/Z-Wave Details, clicked Z-wave repair. It got stuck on that for over 30 minutes so I cancelled
In Settings/Z-Wave Details, clicked Firmware update. It warns that can take up to 15 minutes. It was stuck on that, with a pop up screen stating "Getting Device Versions" for longer than 30 minutes. Remember there are no longer any devices listed on the Zwave page. In the pop up, the Update Firmware and Cancel buttons were grayed out. I finally quit it via the X in the upper right.
When I am logged into the hub, in the upper right, there is a notificaiton icon. When I click on it, it states "Z-Wave is unresponsive."
What is your power source? Try and new 1A or higher supply with a different known working cord.
If the Z-wave still wont come back on, it honestly sounds like its dead. Usually a power cycle brings it back to life.
Do you have hub protect at all? Could try a radio reset and restore if you do. Even without it you could try just a reset to try and bring it back to life (but without hub protect cloud backups you wont have a way to restore it if it works).
You don't think that the z-wave firmware upgrade button seems to have still been available could be a factor? Or, I guess the radio would have come back, just no devices.
The Firmware Update button will always display when the radio is offline. I guess when the radio cannot be reached to check the version then it defaults to showing that button.
Power source was the USB on a UPS. I've unplugged that and plugged the HE into the original power supply that came with the HE, that is now plugged into an outlet next to the UPS
No, have been meaning to but had not yet gotten around to it. I do have backups.
Your local backups do NOT include the z-wave radio data. All devices would need to be paired again if you reset the radio.
I would first try doing a soft reset from the diagnostics tool (see docs below)
First may want to create and download a backup for safe keeping.
Then soft reset and purge logs for good measure. When hub reboots, do not restore from your backup, set up like new hub. Shut down and unplug for 30 seconds then boot again. Check to see if z-wave radio is online. I think this is a rare chance it will work, but worth a shot.
If that does not work I cannot think of anything else to try besides a radio reset (from advanced in diag tool). If this does work you will have to pair every z-wave device to the hub again.
Follow your instructions for soft reset. If that works, I won't need to pair all my z-wave devices again.
If that does not work, I do a radio reset. If that works, I will need to pair all my z-wave devices again. If the radio reset does not work, I will need to get a new HE, and will need to pair all my z-wave devices again.
Yeah that's pretty much it, for #1 if it does work, you will want to then restore your backup you saved and hopefully the radio stays working.
Only downside of doing the radio reset is if I have not thought of anything else that might work other than the reset. Radio reset would be last resort. Nothing else is coming to mind.
I do have a feeling that even the radio reset will fail to reset it if the radio is offline, worth a try though.
After the soft reset it should ask you if you want to restore from a backup, select no.
After it boots up and you can get into the UI then shut down, this is just for good measure to give the radio the best chance to be able to come online with a clean hub,
Unfortunately yes. It's rare that goes out though. Hopefully that will help. Remember to run exclude on each device (or factory reset each device) when re pairing. Also if you get a failed pairing, STOP. Look at yourhubip>>settings>>z-wave details and make sure there are no ghosts...
Yes, and if that does bring the radio back then you could restore you backup.
Before you pair any Z-wave device back though you will need to follow a special procedure to avoid DNI collisions and making a big mess.
Only difference from this is your radio will be reset at the start, otherwise same process.
GOOD NEWS!!!
I did the radio reset, and no longer have a notification that Zwave is unresponsive!! I am interpreting that as having "brought the [z-wave] radio back", and hoping I'm correct in that.
Then, I restored the backup.
Now, I'm stuck on how to edit the DNI.
In settings, Zwave Details, no devices are listed. I presume this is due to the soft reset and the radio reset.
In Devices, for EVERY Z-Wave device, in the Device Information section, in the field under "Device Label", there is no field name, and no data in the data section of the field. HOWEVER, for every Z-WAVE device, in the data section of the field, the text "Zibgee Id" appears grayed out.
This is what it looks like for a Zooz Zen14 (a Zwave Device). All other Z-wave devices are similar.
I presume this is the area where the DNI I am supposed to edit is supposed to appear? What do I do now, since there is nothing to edit?
On the device list page, there is a short number for each in the DNI column, like this:
I could enter the DNI number that appears on the list page, appended with "_OLD", onto the Device Info page in the field that states "Zigbee ID", but I'm afraid that somehow HE thinks all my Z-Wave Devices are actually Zigbee, and I don't want to mess something up...
The DNI (Device Network ID) is found on the Device pages...example below - DNI is A3 for this device. That's what you need to edit for each device, per @jtp10181's instructions - append _OLD to each DNI. Ignore the "Zigbee ID" field - it's always there, but not used w/Z-Wave devices.
