InfluxDB no Data entries

Hello,

im really new to all of this.
I installed OH3 on an Pi3.
Over raspi-config i installed InfluxDB+Grafana.
The shelly 1PM is the first and only item in my system. I configured everything over the PaperUI. I can control the the switch and the power is displayed in OH3. Now i want to make a nice graph with grafana. But when i try to choose which data should be displayed in grafana but the list is empty.
Does anybody has a tip for me?

UPDATE:
I reinstalled Openhabian but the problem remains.
I looked in the log.

Direct after the line “Got a query for historic points” i got an error.
Does this mean there is some data which can be stored but there is a problem with ‘QueryablePersistenceService.query()’?

GOT IT!
I had an false User in my .conf file :man_facepalming:
