I don’t know whether it is 32 or 64 bit integer. ABB manual says that MB reg for imported energy starts at 5000 (Hex) with length 4. Could this mean that if I create a data Thing with reg 20480 and read type 64 bit integer it could work?
I noticed that read type 64 bit has several options. I guess I need to make some testing tomorrow. I think I’ll stick with Modbus RTU until I get OH working with this energy meter and only after that change to Modbus TCP. I want to keep Homeseer running in parallel because I don’t know yet how to export data e.g. to influxDB in OH. Modbus TCP integration in Homeseer has very limited capabilities so I may need to create 4 separate items, one for each register. Modbus devices seem to be rather complex to be integrated with OH. Lot of manual work in configurating them.
