In MIS mode (Multi Inverter Support) the data in the monthly csv-file is off by one day for one of the inverters. The data from the following day is shown. There is no offset in the daily cvs-file. (SBFspot 3.1.1 on Raspberry Pi, 2 SMA SB-3000 TL inverters)
Example data read out on 11.09.2015:
08.09.2015;12272.333;6.697;14028.974;8.178
09.09.2015;12276.658;4.325;14038.063;9.089
10.09.2015;0.000;0.000;14043.744;5.681
The data for the first inverter (e.g. 12276.658 kWh for 09.09.2015) is actually the data for the following day (10.09.2015). On the last day (10.09.2015), because of the offset of one day, a value of 0.000 is given: 11.09.2015 was not yet over and therefore no day data existed. (I do not known about the behavior in older releases, just started with version 3.1.1)
Comments: The issue seems related to different times on the different devices: I use a Raspberry Pi (which has no internal real time clock) to read out two SMA inverters (which have their own clock). I never adjusted time on the inverters since their installation and I also do not change for daylight savings time. After synchronization of all three devices, the readings are correct. (I do not know how accurate the synchronization must be.) That said, it would be extremely helpful if one could set the time on the inverters with sbfspot.
