I’am pretty new to HA but already run into a problem that is not so easy to solve for me.
Nowadays many house-owners already have installed a Photovoltaic system on their roof. In my case that are 10kWp PV Generator Power on a Goodwe ET 10kW Hybrid Inverter together with two 12,8kWh BYD HVS batteries connected to it.
This was the easy part to be added in the HA Powerflow and HA Energyflow Panel, but now there comes the difficult part. There are two additional 1Phase Hoymiles HMS2000 String Inverters (using openDTU to get all values by MQTT) connected directly to the internal house load lane of the system. So they are running more or less independent to the other system simply putting addition energy onto the house load lane if there is solar power available.
One special thing here is that the Goodwe ET Hybrid Inverter has a very nice feature if there is surplus Energy available on it house load lane, in this case and if the battery is not already full charged it automatically takes this energy from the single phase AC and stores it to its battery (BYD).
As this Inverter might be widely used and the so called “Balkonkraftwerke” might become more popular this situation could pop up more often now ?
So how can this be integrate into the powerflow and energyflow panels ?
I already tried with
Any help is welcome.
