  "notes": "Addresses are the hexadecimal \"Address\" column of the iEM3000 Modbus register list in the Schneider user manual (DOCA0005EN) converted to decimal; that column is the address used in the Modbus frame, and the manual's \"Register\" column is address + 1 (0x0BB7 = register 3000). Only function code 03 reads the data (the meter also supports 16 for writing by command and 43/14 for device identification). All measurement and energy values are IEEE 754 single precision; the energy counters use kWh/kVARh rather than Wh, and a second copy of most counters exists as 64-bit integers (0x0C83 onwards) which is not listed here because this format has no 64-bit integer type. Power values are in kW/kVAR/kVA. iEM3150 / iEM3250 / iEM3350 have no reactive or apparent power, no neutral current and no multi-tariff counters. Configuration registers in the 0x07xx to 0x10xx range (power system, transformer ratios, tariff mode) are written with function code 16 as commands, not with a plain register write, so they are not listed."
