  "notes": "Source: SMA Solar Technology AG \"SMA Modbus Interface - SMA Data Manager\", technical information EDMx-Modbus-TI-en-16, version 1.6, status 2022-03-09, vendor-hosted at https://files.sma.de/downloads/EDMx-Modbus-TI-en-16.pdf. Valid for EDML-10 (Data Manager L), EDMM-10 / EDMM-US-10 (Data Manager M) and EDMM-10.A (Data Manager M Lite). The document describes three unit IDs: 1 = the communication product's identity, 2 = the system (plant) and 3-247 = the managed devices; this seed stores the unit-2 system table and sets unit_id 2, port 502 (section 3.5). ADR values are the decimal wire addresses, so addressing is zero_based. The document lists function codes 0x03 and 0x04 without assigning one to the tables; as in the library's other SMA seeds, the 30xxx measured values are stored as input registers and the 40xxx parameters as holding registers. Word order HighFirst follows the SMA profile (32-bit values high word first). Deliberate omissions: every U64 row (30513 total grid feed-in, 30517 daily grid feed-in, 31397/31401 battery charge/discharge) because the app has no 64-bit integer; the unit-1 identity block (30001-30193) and unit 1's own UTC row; the unit 3-247 device parameters, which belong to the inverter entries; and the EDMM-10.A note that all listed points may answer NaN on the M Lite. Sensor values (34609-34635) require the sensors to be configured and activated in the Data Manager; the PCC voltage, current and power-factor rows require a power analyzer. 30193 UTC system time appears in both the unit-1 and unit-2 tables and is kept once."
