In the early days I used to use Domoticz but switched to a combination of node-red and influxdb and grafana as I found the automation system in Domoticz lacking. I am now using Home Assistant full time but what I really miss about Domoticz is its way of agregating historic data.
Domoticz would discard data older than X days but then keep min, max and mean temperature for each day. I cannot remember if it pruned data further down but my point is it would be great if the recorder component could save data in a similar way so that I could keep a longer history.
It would also be great if I could then compare with historic data e.g. this february is x degrees colder than last year or similar
February had x days with frost this year compared to x days last year and so on
