Hi @Timbones - some more info on the minor issue Dom and I commented on previously,
In the new “DAY” (i.e. previous 24 hours) view, the summary data looks good:
The “COP in window” of 3.59 appears correct; lower than the 4.84 when in Heating mode (because I get significant passive solar gain on cold-but-sunny days and my system spends a lot of time pulling 60W in Standby with no heat production).
When I click on the current day on the overview histogram and go into the ‘today’ view (i.e. from 00:00, showing the data up to ‘now’) the summary COP data appears to be wrong:
The “COP in window” looks OK (less time spent in standby so expected to be a bit higher than the 3.58 on the previous image) but I don’t believe the 5.98 when in Heating mode.
Due to the long period in standby, both graphs show the same three heating cycles (no DHW because my solar PV divert covered that) so I was expecting the figures to be identical. While “heat produced” is very close (17.298 versus 17.290) the “Electricity consumed” is quite different (3.577 versus 2.893).
Does that give you any clues? It seems to be missing some of the electricity consumption when working out the COP. Is the calculation looking at the right time period?
