After an update on Saturday, 16 of my Netonix switches’ sensors including voltage appear to no longer work. I have 97 of these switches in LibreNMS and I can’t see any commonality between the ones that no longer poll. Any assistance appreciated.

I don’t have any specific insights to help other than observing it is probably related to a fair amount of polling and function changes in this PR: APC: Add support for Battery Recommended Days Remaining by Jellyfrog · Pull Request #14653 · librenms/librenms · GitHub
This raised issue seem to confirm the same: ASR1001 environmental · Issue #14896 · librenms/librenms · GitHub
Please run this and check if the error disappears:
lnms tinker --execute="\App\Models\Sensor::where('user_func', '')->update(['user_func' => null])"

Worked like a charm. Thanks!
Sensor’s fixed. But server is now very sluggish.
Random PHP errors now showing too. Php is 8.1.17
I’ll migrate it to a new server. Centos 7.9 → Ubuntu LTS was on my todo list anyway.
Thanks for the assistance @Jellyfrog
So I’ve migrated to Ubuntu 22.04, setup a clean install then imported the DB. It’s fast but there’s still the same php errors.
Is there anything obvious I can do to clean this up or should I be looking at reverting from a database a couple of weeks ago?
