It has integrations with allmost all devices or apps I use and the support for DSMR (Smart Electrical Meters) is first class
I plugged a cable into my meter, the usb end into the server and it just works.
It does have a steep learning curve, though. It really seems “by IT people for IT people”
The other think I'm not a huge fan of is it's template language, it's clunky to say the least, but overall it's a great amd flexible system
Updating from that far is probably risky but you don’t need to backup everything, just the config directory. Automated backups to Google drive are worth the upgrade alone.
If I should ever need to rollback I can change the Docker image tag from ‘latest’ to a specific one I guess.
I’ve never had to do it but I do know people sometimes complain about updates breaking things.
`docker commit` should help you there, in making a copy of the container
with BTRFS you can even mount/work with multiple snapshots of same directory at once. it is great for debugging.
deduplication will save you space.
