Notes
RS-485 device: reach it through a Modbus RTU-to-TCP gateway using the factory serial settings above. All values are IEEE-754 Float32 with the high word first and are read/written with function code 03. Power values are reported by the meter in kW/kvar/kVA and converted to W/var/VA here (scale 1000). The tariff time-interval blocks at 0x0300-0x036F are not mapped because their packed date/time layout is model-specific.
