I have a C8 hub with a mix of mostly Honeywell, GE switches and dimmers, and then a few sundry Z-wave devices. I was traveling and returned home to none of the automations working. I have no idea what went wrong but nothing on the device list will respond to a manually initiated on/off command, all automations are non-functional, and the Z-Wave Device Topology map is just wacked!
I still have a bunch of devices with "Last Activity" date that is > week old with several being a couple months old. How should I proceed with all of these devices? Leave them for now, remove/exclude and re-add? Suggestions? Again, thank you.
Click refresh, or physically activate the devices.
The last Activity will only update if the hub hears from them.
If your z-wave radio was down for a week it may take 24-48 hours for all the devices to fully recover. They may need to rediscover the routes to the hub, which cannot happen until the closer devices are working first.
Well, after close to 48 hours it seems things haven't improved beyond the Z-Wave graph appearing to have recovered.
No automations were running after waiting for the environment stabilize so I checked on the device page and found that while I can see them listed, they are no longer responding to simple on/off commands. Many of these devices were working but they are not working any longer. I am reaching out again for suggestions.

Shut down hub and unplug for 30 seconds. Once it is back up focus on one device. Pick something closer to the hub. On zwave details run a repair on it. Try activating the device physically a few times then from the hub a few times. Results?
Repair complete on a device located right next to the hub. Physical on and off changes are event logged. All attempts from the hub fail, nothing in the event log, no change to the light. Do I need to wait longer for the Z-Wave repair to stabilize or propagate?
Why is that the desired state? The first column for the hub is mostly blue now. The horizontal hub line (first row) remains mostly red. It's not clear to me how to read this chart and I didn't find any documentation about the chart either. I don't yet understand what optimal would/should look like and why.
I tried another power supply with no change in status.
None of the devices are talkative. I really only see logs from me initiating an action.
Since the power source change didn't help, I swapped it back so that I'm not introducing any new variables to this effort.
Here is where I'm at now:
Powered down the hub
Swapped antennas
Powered up the hub
Ran Z-Wave repair, initiated from another close by switch
Rechecked the topology map and the first column has the most blue hub connections
Most of the devices are responding to Hubitat initiated on/off commands
I have 3 wall switch devices that remain unresponsive, with no blue box hub connection anywhere
I plan to exclude/remove them one by one and then include them back in if their Z-Wave logic controller and radios are still operational.
I don't understand what might have triggered such a catastrophic failure as this. I would like to better understand that so that I might be better equipped to monitor for the pending failure in the future. Any thoughts on that? Regards, Bryan
If your Zigbee now goes to hell you have a defective antenna. Possibly the antenna was just not making good contact for reason though and swapping them cleared that up?
Otherwise possibly the zwave radio locked while you were gone and due to the extended outage all the devices routes got all screwed up and it just took some coaxing to get them to recover.
First column or first row? or both? Ideally both should be nearly all blue. That map is the neighbor map, so if 01 is Red that means the hub or device thinks they are out of range of each other. I think the top row is if the hub sees the device as a "neighbor" and the column is if the device sees the hub as a neighbor.
So everything else is working now except 3 devices? Thats great!
