ElectricityMeter - Range of Current Channels

[Sn0w3y]

@tsicking

a) change the documentation and define the range of the current channels to be positive, or
b) add some logic that applies the sign of the active power to the current?

Nothing of it is applicable here. See:

Yes, Edge sends a EdgeConfig object to UI, that holds information about all Natures, Components and Channels. This is used to dynamically build the UI. This is not the way OpenEMS Edge works. OpenEMS always calculates the Consumption from measured Grid, Production and ESS. If any of those is not there, it is assumed to be zero. The code for this calculation is here: https://github.com/OpenEMS/openems/blob/develop/io.openems.edge.core/src/io/openems/edge/core/sum/SumImpl.java#L359-L360C24 In …

What’s the exact problem? If I understand it correctly: you are setting channel values on component ess0. State-of-Charge (SOC) is coming from JSON as "BtSoc":51 and result in 51 % for ess0/Soc Active Power (ACTIVE_POWER) is coming from JSON as "GridPw":0.04; you convert kW to W by multiplying with 1000, resulting in 40 W for ess0/ActivePower You configured only ess0, there is no meter. Consumption is calculated using this formula: (-> https://github.com/OpenEMS/openems/blob/develop/io.opene…
