Thanks for elaborating.
Few if anybody except electricians cares about phases.
As per regulation all phases must be added (at least in DE and I wouldn’t think it’s different where you are) and most meters (or inverters if queried though those) I know have registers/channels for accumulated grid feed-in and accumulated generation, eventually.
Yes some vendors are braindead from outer space and do not provide accumulated values so you have to add up the phases yourself like you do in your rules but don’t the following items show 3ph-accumulated values on your system?
Number:Power Fronius_Grid_Power "Fronius Grid Power" <energy> (eFroniusSymoInverter,gHistory) [Measurement,Power] {channel="fronius:powerinverter:mybridge:myinverter:powerflowchannelpgrid"}
Number:Power Fronius_Load_Power "Fronius Load Power" <energy> (eFroniusSymoInverter,gHistory) [Measurement,Power] {channel="fronius:powerinverter:mybridge:myinverter:powerflowchannelpload"}
Number:Power Fronius_Battery_Power "Fronius Battery Power" <energy> (eFroniusSymoInverter,gHistory) [Measurement,Power] {channel="fronius:powerinverter:mybridge:myinverter:powerflowchannelpakku"}
Number:Power Fronius_Solar_Yield "Fronius Solar Yield" <energy> (eFroniusSymoInverter,gHistory) [Measurement,Power] {channel="fronius:powerinverter:mybridge:myinverter:powerflowchannelppv"}
I’m not getting this. I might be misunderstanding the terms you use (“channel in and of itself” ?) but with no battery involved, there’s nowhere else power can flow, and all phases are monitored, so generation = feed-in + consumption no matter if it’s about power (kW) or energy (kWh).
Granted the sums may be some % off due to rounding, different measuring intervals etc and some self consumption losses, but they should match roughly.
Isn’t that (for power) in terms of your items
Fronius_Solar_Yield = Fronius_GridPower + Fronius_Load_Power
?
