Use Grafana with InfluxDB Friendly Name


I’ve set up Grafana and I’m getting along reasonably well.
Since my Entitiy IDs are not good, in the code for InterfluxDB
added the following:

   - friendly_name
   - hidden

I found it here in the forum - unfortunately I don’t know that well.

Now I can actually select by Friendly Name in Grafana. However, “no data” always appears. See photo.

What can be the reason?
