I have a question about the Modbus binding in regards to a Wallbox.
I got the ABB Terra AC 11kw Wallbox. According to the specification this wallbox can communicate over Modbus , ( ModBus-RTU-Bus-Master ).
What is the way to connect to openHAB if at all possible?
From what i read this needs a converter modbus rtu to tcp/ip, correct? The second question is, can a Modbus master communicate with openHab at all? From what i understand Master just do request informations or am i wrong.
Thanks for sharing some insights. I am pretty new to this, so sorry for these basic questions.
