Data logging has stopped

Hello,

At about 0100 in the morning a few days ago my emonpi stopped logging data. The time of day suggests it wasn’t something I did / knocked etc. Disk space etc all looks fine, and a reboot hasn’t fixed the issue. Any suggestions?

Is it just an EmonPi from the shop, noting added or removed?

Can you please post a portion of the emonhub (menu option on LHS), please?

[edit]
Have you run an update or anything else happened such as a power cut, lightning?

Hello! Thanks for the reply. Whilst a reboot didn’t work, a shutdown, power pull, restart seems to have done the trick, so it seems it was not an issue with the Pi side.

Just for info, no - no updates, no power issues (and the 5v transformer is on an online (so pure sine wave) UPS) and nothing else I can think of.

Is there any data I can provide you to help troubleshoot for other users, or shall I consider this “closed” unless it happens again?

Cheers again,

Unless you pull the logs (there should be a weeks worth I think in the logs folder) it is pretty difficult to dig any deeper. Probably just one of those things.

Yes, complete removal of power does sometimes reset things completely.

I’ve just scp’d the /var/log dir and am happy to send if you think you’d learn anything from it?

Sorry, no I haven’t got the time to scan for a random error :slight_smile:
