I have installed a wallbox. To know about that a little deeper I use a ET340 on /dev/ttyUSB1 to grap the power values. The wallbox has an VRM instance id of 30. Maybe I'm blind, but I'm not able to find this device via query.
How is this AC Load device declared?
The role of that ET340 is declared as 'AC Energiemesser' (in German).
N/xxxxxxxxxxxxxx/??????/30/#
Maybe someone has in idea.
