1 year ago Hi Tommy, German is OK for me but we use english here to make the stuff readable for as many people as possible 😀. Please write which BMS you have and attach the schematic diagram of your installation as well as the screenshot of dbus-spy. You are the first guy reporting about MPPT RS. I have no experience with this device yet.

Hello,
found the problem. It was me, had a typo in the rc.local.
I have a Solarlock BMS(JBD-SP25S003-L16S-100A-B-U-R)
Unfortunately, there is no circuit diagram at the moment, as everything is still under construction!
Thanks for the help

Hello , unfortunately "aggregate-batteries" doesn't work for me. At the moment I only have a DIY battery that is integrated with “dbus-serial-battery” and works. After installing “aggregate-batteries” my PV charger disappears from the “GUI” on the CerboGX. A menu item for the tool does not appear either. If I turn it off again, everything goes back to normal. I have an MPPT RS450/200, 3xMP2/5000, GerboGX and SmartShunt.
Do you have an idea what could be the reason?
Greetings Tommy
Hallo , leider funktioniert “aggregate-batteries” bei mir nicht. Zur Zeit habe ich nur einen DIY-Akku der mit “dbus-serial-battery” eingebunden ist und funktioniert. Nach der Installation von “aggregate-batteries” verschwindet mein PV-Ladegerät von der “GUI” auf dem CerboGX. Ein Menupunkt für das Tool taucht auch nicht auf. Wenn ich es wieder deaktiviere wird wieder alles normal angezeigt. Ich habe einen MPPT RS450/200, 3xMP2/5000, GerboGX und SmartShunt.
Hast Du eine Idee woran das liegen kann?
Gruß Tommy
