Grafana updates half of the graphs from the same data source

Hello everyone,

  • What Grafana version and what operating system are you using?*
    7.1.0 as Home Assistant addon on RPi4

  • What are you trying to achieve?
    Updates all the graphs.

  • How are you trying to achieve it?
    I’ve restarted systems. Configured influxdb (also home assistant addon) and grafana once again but it didn’t help…

  • What happened?
    Everything was fine until it wasn’t… The data for both panels are from the same data source which is influxdb, which obains it from homeassistant. Everything was working as I created these graphs and now one of them (the gauge on the right) gets no data (even if I refresh it manually or delete the panel and create a new one with this data.


    Below you can see that the homeassistant gets the data from my RPi…

  • What did you expect to happen?
    The graph to work as it worked before.

  • Can you copy/paste the configuration(s) that you are having problems with?

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

Do you have any idea what could be the cause of this problem and point me what I can google to fix it? That’s actually the only “sensor” that doesn’t work in my grafana…

Really? Grafana version 7.1.0?

Are you sure you don’t mean 8.1.0?

  • What happened?*
    Everything was fine until it wasn’t…

What changed between the two?

  • just a reboot?
  • anything (HA, Grafana, Influx, anything) upgraded?
  • config adjustements?

What did you expect to happen?
The graph to work as it worked before.

Can you restore from backup just to check that “before” still works as it did?

I’m puzzled as to which part of the system now is not as it was “before”, but
it’s currently a bit hard to understand “before what?”
