Grafana shows "Datasource TeslaMate not found" although there is plenty of data

Is there an existing issue for this?

What happened?

I installed TeslaMate as home assistant (HA) add-on on a rpi4. TeslaMate is connected to my car without errors.
Postgres15 (HA addon) is used database (no errors). The database is properly connected with teslamate (see logs) and Grafana.
I can read data manually in Grafana from the database (see screenshot), however none of the nice Dashboard works (screen shot). I get always errors e.g. db query error: pq: invalid input syntax for type json or db query error: pq: invalid input syntax for type smallint or dib query error: pq: syntax error at or near "ORDER"

Settings:
Raspberry Pi 4
Home Assistant Core 2024.12.5
Home Assistant Supervisor 2024.12.3
Home Assistant Operating System 14.1
Home Assistant Frontend 20241127.8
PostGres addon: 15.7-14
Grafana add-on: 10.2.2
Teslama addon: 1.4.0

Expected Behavior

I would expect to see data in the dashboard.

I am not sure if this is helpful in the discussion, but in the grafana panel I cannot select/see my car. There is just a big "!"
So could it be that the car is not selected, which results in no data? How can I select the car?

Could you share a screenshot of the connections defined in Grafana?

[hemy81]

Thanks, I got no connection errors. Here is the screenshot

[swiffer]

Name of the connection should be TeslaMate

[hemy81]

Even if the name of the database is:
Creating database 'teslamate' on db21ed7f-postgres

[hemy81]

Right ! Thanks now it works

[swiffer]

The connection identifier for grafana must be set to TeslaMate. Glad to hear it works.
