Nice site I use it daily.
I also use the Auto Refresh feature, that works fine.
When I use compare mode (also a nice feature), only 1 of the 2 is refreshed.
E.g. https://pvoutput.org/comparelive.jsp?sid=47702&sid1=67164&dt=20190706
Best regards
The second system is refreshing but it is recording at 15-minute intervals, vs 5-minutes for the first, which will not show as a continuous line in the updated compare graph.
