All new to Grafana. Working on hobby home weather station.

Weather sensors slowly send update every few minutes to save battery.

Need pointer and advises on how I can ‘trigger’ Grafana **as soon as new data arrive** , instead of Grafana perfroming **auto refresh** at time selected on top-right corner, to read data base and produce an updated version of the data chart?

There is no trigger for that. But you have to stream data. Example showcase:
