I originally set up my Raspberry Pi system (ioBroker, influxDB, Grafana and deCONZ) to have a correct and “empty” installation and then wanted to make a backup of it in the initial state.
That’s why Grafana 7.04. installed in the “empty” system.
The core plugins didn’t work.
Now I had the following idea: I had installed grafana_6.2.2_armhf and then Grafana 7.04 as an update.
And everything seems to be fine so far.
The plugins appear on the page and can be inserted, parameterized and displayed.
The combination is as expected.
