@fabrix76 added support for Grafana 7.x

Please give it a try and let me know how it works.

You may test it with Docker:

docker run -d \
  -p 3000:3000 \
  --name=grafana \
  -e "GF_INSTALL_PLUGINS=https://github.com/vsergeyev/loudml-grafana-app/raw/master/loudml-grafana-app-1.4.0-grafana7.zip;loudml-grafana-app" \
  grafana/grafana

Hello @vsergeyev,
thank you for you quickness :) i had installed new package and now it works, but I get an error using it.

I had configured LoudML datasource, after in a dashbooard i get a panel "loud ML graph", i'm going to use an influx DB (called "generale_casa") where i get the mean value of a field group by time (30s).

Influx datasource name: Influx-IoT
influx query: q:"SELECT mean("Potenza") FROM "generale_casa" WHERE time >= now() - 6h GROUP BY time(30s)"

Using "create baseline" i get this error:

"Model create error
invalid field features.0.default: not a valid value"

in panel, under Display here you are
input bucket: generale casa
output bucklet generale_casa_ml

here the configuration of loudml

buckets:

• name: generale_casa
  type: influxdb
  addr: 192.168.1.40:8086
  database: IoT
  measurement: generale_casa
  retention_policy: autogen
• name: generale_casa_ml
  type: influxdb
  addr: 192.168.1.40:8086
  database: IoT
  measurement: generale_casa_ml
  retention_policy: autogen
  annotation_db: generale_casa_annotations

Actually generale_casa_ml doesn't exists, because is where i would like to insert my prevision of measurement.

@fabrix76 ,

"Model create error
invalid field features.0.default: not a valid value"

This is about fill() option if Group By. LoudML supports 0 or "previous"
https://loudml.io/en/loudml/reference/current/timeseries-dsl.html

This is not-intuitive from UX in my panel, let me put a fix to improve it.

generale_casa_ml bucket should exists probably, I'm not sure if LoudML will create this database based on config. @regel may help.

Thank you very much @vsergeyev ^_^

Just another thing, i don't if this is an issue, but in legend there is something
row doesn't get column name but it is generic "value", and there isn't any value (min, max,average total etc)
Looking in display it seems missing about toggles to select what show in legend, so it is empty.

hope to be useful for you

regards
