The question as followed:
-I only know the RAW data store at table ts_kv， ts_kv_latest， but actually I don't understand how the things board store inside the data if like that any way or link that can see/know the data inserted， do I able to query historical data from Pgadmin
-There has time interval at the dashboard and that can set by the customer, but it not functioning, is that any setting can if I want to change and let the customer query the data?
-Anyway to capture dashboard data or from rule chain and save as historical data in DB ? I saw it have a download option (Json) but not sure how it can save into database instead?
-Beside Things board web site, any recommended learning platform for Things Board ?
