Would be nice if you could write up something of combining OpenHAB and InfluxDB with Grafana.
I have a friend who implemented Grafana + InfluxDB here to log all my temperature data from the KNX bus but since OpenHAB can do the same I would like to centralise this stuff.
InfluxDB + Grafana + KNX was a little bit too much for me. AMA about vSphere (ESXi) or Hyper-V but as always the road to getting something to work under Linux is steep as ****
You don’t have any experience with Sonos and OpenHAB do you?
