Hi,
my name is Dominic. First and foremost, I’d like to mention that my native language is German, so please bear with me.
Grafana 9.1.6 in Docker
InfluxDB
I would like to add 2 values from my PV system. Unfortunately, the result is often not appropriate. Even with Reduce and Resample, I have not been successful so far.
Perhaps you have a tip on what else I could try.
Is it possible to use later version of Grafana? Similar problem was solved by update, check this topic:
Unfortunately it is not possible to update, because it runs on a special Homeserver.
you could try an “add field from calculation” transformation
That doesent work, too.
The transformations dont work?
first …concatenate fields and then calculate the total…??
what does your raw data look like?
I got it. 
The problem was the dashboard time range from now-3d to now+1d.
After i went to the query options and set the relative time to 24h, it worked fine.
Thank you very much!
