I have an existing Hybrid high voltage solar inverter from Sofarssolar and want to to display the Hybrid Inverter Battery and PV generation in the Venus display. I already did a driver for the hybrid inverter display itself as a Smart grid meter and also as a normal PV inverter. This works well also with the ESS assistent (grid point 0W).
However I would like to have the battery data, the charging and discharging data displayed to have everything on one display. Is there some means to tell venus, that the second battery is not connected to the Multiplus but separate?
Currently it look like this:
I would like to have it look like this (and maybe even include the solar generator):
Is there any solution to this common problem of extending an existing system?
