I just installed influxdb (v1) and grafana using this howto and it works ok. I just installed it on a Debian 11 server, no docker.
Do you see a number other than zero at ‘Measurements’?
In what way do you query the database?
On the server with influxdb I installed influx client
On Debian I did:
sudo apt install influxdb-client
Open the database:
influx -database 'homey' -precision rfc3339
Then the command line changes from ~$ to >
Now enter select * from “DeviceName”
An example device:
select * from "1.Growatt_Solarpanels"
This results in a list of these lines:
