Error description

Changed from 0.8.83 (stable) to 0.8.94 (dev) today because of the MQTT bug in firmware 0.8.83 which prevented HA from discovering the DTU. There was then a sudden jump in total yield from 713 kWh to 740 kWh (and respectively on the two channels). There is no such jump in the daily yields. It looks like the total yields have been recalculated resulting in a higher value.

There was a effiency factor for older versions. The default effiency was 0.955%. For you values it would calculate as: 740kWh * 0.955 = 706.7kWh

Check also issue #1243

Ah, I see. So the factor was removed. Thanks.
