this is my first question here, so please don’t be mad at me if I do something wrong, e.g. not giving you enough or the right info.
I’ve been playing with openHAB for a few days now. I have no programming skills, no Linux skills and started completely from scratch,- total noob, so to say.
openHABian is installed on a RPi 3, connected via WiFi.
Everything appeared to be stable so far, I got all my things and items added (Z-Wave, WiFi, Hue Bridge with plugs, bulbs and motion sensor, openocean), ~20 things total.
Since I found the rules engine it started to be fun, but the more rules I added the more I thought about what would happen if the system crashes with all the work lost. So I wanted to do a backup as descibed here but I couldn’t access the Pi with PuTTY anymore: “Network Error: Software caused connection abort”. The log on port 9001 wasn’t accessible either.
Paper UI and rules are still working normally.
So I pulled the plug off the Pi because I didn’t see any other way to shut it down “softly”. I had to pull the plug two more times for the Pi to boot successfully.
Now it was accessible again and I ran the first script
./runtime/bin/backup
and it failed, it always said “can’t create… folder is read-only.” After this: the same problem as before. After a short time I can no longer connect to the Pi via SSH (and some other things like the log are messed up too).
Use openhab-cli backup instead. This shortcut deals with folder locations automatically. I believe the issue was that you weren’t in openHABs root folder?
If you still have issues using that command, could you post the results of openhab-cli info?
Thanks for the quick reply, Ben. After another “hard reset” openhab-cli backup worked and it got me a zip file! Awesome. How do I apply that backup zip when I need it?
But my main problem was that the system beyond the web UI crashes in some way and the only thing I can do is cutting off power. How can that be? Could that be a WiFi issue? Might it be helpful to do a new setup with Ethernet instead?
Edit: log viewer is still not working, even after reboot… trying to reinstall it with config ends with some memory access error.
Keep that zip file somewhere safe, it can be applied by using:
openhab-cli restore /path/to/zip
The default location is /var/lib/openhab2/backups but you might want to move it somewhere separate.
Hmm, sudden lack of access to ssh implies a problem on a system level, not just with openHAB. You could try using Ethernet, but it would also be a good idea to check if the power supply to the is stable.
Thanks for the info about the backup, because I think I’m gonna need it. After two days out I came back home and again something went wrong in the meantime. No rules working, neither UI nor SSH connection possible. In PuTTY I get asked for username and password, but after this no further reaction.
I bought a new 3A power supply. How do I check if it is stable?
