Read out attached DTSU666 Chint ? #22

Hi, great work. It works nicely on a dtu pro s with HMS-2000-4T attached. I have a DTSU666-CT attached via RS485 to the DTU. Is it possible to get the data from the smart meter? This would really help.

Unfortunately, the manufacturer did not provide such fields in Modbus. The easiest way would be to connect DTSU666 to HA and not to DTU.

Hi Arek, Thanks for linking into this. The dtsu666 is required for export management using the DTU. So unfortunately not an option. I was hoping that the meter values were hidden in some undocumented fields.
