We still have issues with data missing in grafana from time to time on some timespans. Not sure if it is Grafana or the datasource. I was hoping it should dissapear after the latest Grafana update but it is still ther.

can you confirm that it actually landed up in timescaledb? could also be that the mqtt broker restarted or similar

no i mean, the data comming in to grafana is correct as you see in the timestamps.. the data is UTC+0 and the browser is UTC+2 atm, so grafana should render the data with +2h but it sometimes fail.. i have not seen that behaviour from queries direct from sql.

if it appears there, then it is probably not a datasource problem, but a visualization. can you check if it appears with different visualization options as well? e.g., a table

table looks correct if i remember. also gauge works.. i have not however had the same problems when getting data from the database.. if i have time tomorrow i will create a copy of the visualization but use postgres instead and see if i have the same problem.
