Just quick update that it was very easy to get this working on HASS.IO.
InfluxDB and Grafana hass.io add-ons here:
Repository: Bestlibre Addons repository
Need to create DB with following command line:
curl -i -XPOST http://hassio.local:8086/query --data-urlencode "q=CREATE DATABASE home_assistant"
Good guide for grafana config:
