Hi,
I´m using Grafana 9.0.5 and InfluxDB 1.8.10 on a Raspberry PI 4 (buster).
I performed an update from an older Grafana 8.x version (I don´t know exactly).
Simply used #apt-get update and upgrade.
Now Grafana seams to round up values queried from influxDB.
These are the example values from InfluxCLI:
> SELECT max("value") FROM "Kuehlschrank-Total-kWh" WHERE time > now()-30m GROUP BY time(1m) fill(null)
name: Kuehlschrank-Total-kWh
time max

Using the same query in Grafana => Explore shows just 315 as value:
