There is a minor bug with DESS grid setpoint. It does not seem to honor the ESS setpoint I applied in the Cerbo. I think DESS should honor it. It seems to be currently using some hardcoded default value, maybe 50W.
I have about 30W offset between my VM-3P75CT and electricity provider grid meter, which causes 80W constant buy with DESS in self consumption strategy.
With only ESS, I use -20W setpoint, which comes out to pretty much zero actual consumption, only a little bit of import on average.
I also use this feature. The reason is that the measurement coil measurement is 20 watt higher than the measurement of my electricity provider. I did not check if this setpoint is still honored.
I updated from ~59 with the bug to ~69, and it now seems to honor the setting! I had not noticed any mention about this type of fix in the changelog, so I only thought to try updating now. Will keep monitoring if the issue comes back. Excellent. Thanks and sorry for the possible unnecessary report.
I did test it also, indeed when I set it for example to -200 I see discharging to grid around 200 watt which is correct behavior.
