Generally I use Grafana directly to see this data from multiple buckets. I don’t know how you can see data from multiple buckets directly in OH other than embedding a Grafana chart (see Grafana chart with time ranges).
Maybe someone else has ideas on this can be done directly in OH?
By the way, this is what some of my temperature readings look like in Grafana. You can see the short term storage followed by the once per day min/max that goes forever.
