I have a raspberry 3 running with Venus OS as a Cerbo GX which is connected to my Fronius (Symo) Smart Meter and to a Multiplus II
The MP2 is only connected in Parallel with the AC 1 on the grid.
The Raspberry communicates via Modbus TCP with the Fronius Smart Meter
I will add some Pylontechs by the end of the week.
I´m using the https://github.com/RalfZim/venus.dbus-fronius-smartmeter script and for the can communication this https://powerforum.co.za/topic/4307-venus-pi-pylontech-integration/
No I have the following problem:
As long as I do not connect the MP II with the Raspberry via MK3, the "Cerbo" shows the correct visualziation. As soon as I connect the Multiplus (icnluding the ESS Assistant), the visualization seems to be wrong. The Fronius Smart Meter shows for all values "0"
If i disconnect the MPII from the Raspberry, the the problem does not disappear - only a new installation of the Venus OS solves the problem
and the AC-loads shows always almost the same amount as the PV inverter. :
(in the moment of the picture,453 W are produced by the PV and 105W are taken from the grid)
The connection of Fronius Smart Meter and Raspberry in general works, as long as I do not connect the MP II
Has anybody any clue where I could have made a mistake?
