ENO one / SingleWallBox (also Shell Recharge Home Advanced, NewMotion Lolo) Modbus register map

Notes

Source: Enovates' own published register map for the ENO one - the register definitions in the vendor's enovates-modbus library (https://github.com/enovates/enovates-modbus, src/enovates_modbus/eno_one.py: every block carries its base address and every field its data type) together with the field list and semantics in that repository's README. This is the vendor's own code rather than a PDF register document, and it is named here so the source can be checked line by line; evcc's enovates driver reads the same block addresses. The transport facts: Modbus TCP on port 502, holding registers only (the library reads with FC3 and writes with FC6/FC16), big-endian, device id 1 as the library's default (evcc's template also uses id 1 - a secondary source, since the vendor code ships the id as a constructor default rather than documenting it). EMS-over-Modbus has to be enabled on the station by the installer or via OCPP (the setting is called "EMS mode" and has the states off / monitoring only / full control); the vendor library requires Modbus API 1.2, i.e. firmware 2.13 or later. In monitoring-only mode the EMS limit (400) may accept writes but ignores them and the transaction token (401) cannot be read; only full-control mode makes 400 genuinely writable. Booleans are single registers returning 0 or 1, and the vendor README warns that the Mode 3 details (300-307) can give a false impression of a car's behaviour on ISO 15118 vehicles, so the offered current (417) and the measurement block (200-217) are the recommended rows for power management. The same map is sold as Shell Recharge Home Advanced and NewMotion Lolo; both are rebadges of this station and are covered here, not seeded separately.
