Hi!
I am trying to install a plugin for Grafana. I have installed Grafana through Home Assistant.
I tried to install it locally through Docker: https://grafana.com/grafana/plugins/natel-plotly-panel/installation
Everything went well, but the plugin wont show up in HA/Grafana after restart. There seems to be a config file somewhere, but I can not find and access it on my server (Ubuntu 18.04).
Please help a Grafana noob
