Hello @rlkoshak,
That’s exactly my vision for my data future in oh3, but to realize this by myself I have not enough programming skills and database knowledge. Actually I am trying to uso influxdb and rrd4j but I have starting problems to use influxdb with oh3 (see Using my old oh2 influxdb database for oh3?).
Important for me is the data history.
Thank you for triggering this!
