I have a "standard" MultiPlus 3000, 2x Pylontech US2000C setup (with GX device in a parallel network setup). I want to install an EM24 for ESS in future. Problem: My energy meter must be extended for this and I will not get an installation in the next months..
In the meantime I'd still love to have ESS running. Using some "light-diode" reader on my smart meter I know the current consumption on all phases on an raspberry. Using this reader I'd like to pass these values to ESS. For the moment I see two options:
- Use ESS Mode 3 - while this will probably work (I will test soon), I can not really get a feeling on how ESS will work, and also wont see my real "savings" in VRM.
- Use ESS Mode 1/2 and somehow push the current consumption per phase (via e.g. MQTT) to the GX device. Here I can not find a writable register, or any explanation on how that could be done.
Does anyhow ever tried the second option?
