Just noticed that the readings on the power graph card now show as having been taken on exact five minute timings 00:00:00, 00:05:00, 00:10:00 etc.

Not sure what is going on as this also applies to all the historical data back to when my system was installed. In the past the data points showed roughly five minutes apart on any minute of the hour and at a varying number of seconds. For example 00:01:47, 00:06:51, 00:12:05 etc.

Timings on the inverter card options (battery, inverter, PV, grid etc.) still show as they always have done and all the values (except time) match what appears on the power graph card.
