  "notes": "Source: the evcc meter template https://raw.githubusercontent.com/evcc-io/evcc/master/templates/definition/meter/ibc-homeone.yaml, used as a secondary source; no IBC Solar register document was retrieved. Modbus TCP runs on the inverter's own Ethernet port (marked RJ45-7 in the template's requirement note), not through the WiFi dongle, and the grid values come from the external smart meter wired to the inverter - so the meter rows read 0 or nonsense on a unit without that meter. The template offers RS-485 and TCP access on port 502 with unit ID 3; this seed records the TCP path (port 502, unit ID 3) because the template states no serial framing. Address convention, quoted from the template: the registers are the documented ADDR(DEC) minus the leading reference digit minus 1 (documented input register 31601 -> 1600, documented meter register 360039 -> 60038); this file lists those wire addresses and declares zero_based addressing. The map is deliberately short because that is all the cited template publishes: it reports grid power per phase, PV power and energy, battery power and SoC, and nothing else."
