Just came home from vacation and lights do not work. Hubitat C-5 rev 2.3.0.116 is online. Device list is available. Remotes has no contact with hub (=flashing red when I press keys). Turning on/off from Devices does not work. Z-Wave Details are empty (see below). Repair Z-Wave finishes in just a few seconds. Zigbee remotes and my single zigbee lamp works perfectly. Restarting Hubitat makes no difference.
I guess I'm screwed and the hardware is broken? I am in Europe - is Z-Wave on the external USB stick, or is it built-in? If it's the stick, could I use the Aeotec stick I have lying around?
You probably just need to cycle power. Do a shutdown via the menu. Then pull the power plug from the wall... (to prevent the delicate Micro USB from breaking.) Wait 30 seconds and power it back up.
What's probably happened is that the ZWave radio got 'jammed' and is not really answering. Shutdown alone isn't enough, it's a power cycle that restarts the Z-Radios.
This won't explain Zigbee or Z-Wave troubles, but it also looks like one of your apps (app:31) is throwing an un-handled error, which could be bad news for whatever (I assume?) integration that is. If you aren't sure what it is, clicking the red "error" box (or any similar box) on any of those app:31 lines will take you directly to the app, or clicking "app:31" will filter the list to just those entries and highlight the app name at the top.
Again, probably not your biggest problem, but...possibly a problem.
On a C5 European hub, Zigbee is built-in and Z-Wave uses an external USB Radio stick. If that external Z-Wave USB radio is removed, the hub may try using its internal North America frequency Z-Wave radio.
Another option. Make sure your stick is in of course. Go to yourhubip:8081 and do a soft reset. When it comes up restore the earliest backup you have. Once that is done, shut down from the settings menu. Unplug hubitat at the wall (not the hub) for about 5 mins and power back up. See how that works for you. It sounds like you have a corrupted DB, this probably would fix it.
I am somewhat at a loss as to why it works, but it does. I left it powered off with disconnected cord while at work (last try it was somewhere 30sec-1min) and jiggled the USB dongle a bit before powering it on again, and now it works. I'm guessing the dongle, although a) it was firmly in place before, and b) no one has been here, so it can't have been moved.
Sometimes just reseating connections is all it takes. I used to repair POS systems for a large retail pharmacy and can't count how many times I drove hours just to reseat a connection.
