It appears that the "last15m" "last60m" reading for data7 heartbeat are now counting too many times during these time periods.

Does that mean that "last24h" is also counting too many times?
[*]
last15m_data7_valuesum_int 16
last60m_data7_valuesum_int 61

The data looks normal

That heart beat thing is a tricky one :-)

When computation of "last15m" starts, Meteohub takes actual time minus 900 seconds as a starting point to look for heart beat entries in raw data. While Meteohub is doing this new heart beat entries might be added. Metohub continues evaluating raw data until end of file. So a new heart beat that has happened during evaluation already running is also taken into account. I will introduce an end marker to keep the new entries out of evaluation.

Hopefully, I am not boring you with details, but I wanted to explain, why Meteohub might register a heart beat too much, especially, when system load is high and evaluation of data takes a bit longer.

Actually I like the details about what's going on in the software. I think a lot of us here enjoy that sort of thing. :)

I can understand how complicated it is with timing, because time never stops and so you have to know and plan where the program will be in the future and take that into count.

Good luck and thanks for the insight!
