Since years I’m now using OH, and the meanwhile 4.0.4 version for monitoring, my temperature, etc values, and
make dem visible in views.
As I have had an poweroff some weeks ago and have had to restart, I noticed, that some values are missing,or better to say, has lost all the recorded somehow lost.
So I got the tipp, from @hmerk to change the configuration in the RRD4J from “everyChange”, to “everyChange, restoreOnStartup”.
When changing the settings, save them, and doing reboot from the RPI4, NO RECORED ARE MORE VISIBLE.
What could be the Problem?
That screenshot indicates you don’t actually have a persistence configuration at the moment. You’ve got strategies for sure but no configuration. You need to click “Add configuration” and your Items to the configuration.
