Zwave entities lost names, default back to originals?

Configuration
1

Things were not responding so I rebooted. Zwave didn’t come back up so I shutdown, unplugged and started up it back up. I noticed some of my lights were no showing up and after looking through the logs I noticed their names were the device brands and now what I named them. It looks like most (9 or so) did this. What could cause this, is there any way to change it back or will I have to remember what they were (for automations) and fix it?

I think this can happen when the zwcfg file gets deleted (or corrupted?). I think it’s possible that with bad timing if you force stop the openzwave process right as it is about to write a new configuration, the configuration could get wiped out.

Then it would be regenerated from scratch, and end up with default or no names. Unless you have a copy of a known good zwcfg file that you could restore, you’ll probably have to look in your configuration files for the names you used, and rename the nodes to those names again.

Yeah, so for future searches. My disk ran out of space which probably cause a corruption. When I restarted HA, it recreated the zwave conf (or part of it?) and thus my names where gone. I was able to rollback (Thank you git) to a month old revision which is only missing two devices which should be easy to add back.

Thanks!

sounds like the same sort of crazy behaviour I had when my SD card was full. Deleted the DB file and all is sweet. Best to create a rule for the DB to only keep a couple of weeks worth of data so it doesn’t eat up all your space.

put this in your config.yaml

recorder:
  purge_interval: 2
  purge_keep_days: 14
