  "notes": "Source: SMARTFOX GmbH \"Modbus-Register SMARTFOX Pro / SMARTFOX Pro 2\", register list v22e (00.01.03.10), vendor-hosted spreadsheet https://smartfox.at/wp-content/uploads/2022/12/Modbus-Register-SMARTFOX-Pro-SMARTFOX-Pro-2-v22e-00.01.03.10.xlsx, sheet \"Register EM2 00.01.03.10\" (Start/End/Size/RW/Function codes/Name/Type/Units/Scale Factor). The workbook's \"Config\" tab gives the factory settings: Modbus TCP on port 502 to the LAN address, and on RS-485 unit 1, 9600 bps, parity none, 1 stop bit (LAN path used here, so no serial block; 1 is the address on both paths). The sheet's Start numbers are 4xxxx register numbers and the workbook's own 'Config' tab gives the device's address offset as -1, so Start number N is read at wire address N-1 (Start 40010 at 40009, Start 41038 at 41037); they are the vendor's own register numbers, not Modicon 4x references counted from 40001. They are stored as printed with addressing one_based, so a client's subtract-one step lands exactly on that wire address. Omitted because the app has no matching type: all 64-bit counters (41000-41011, 41402-41427, 41600-41643, 41712-41759), the uint8 control surface (40400-40406, 41608/41609, 42207/42208, 42250-42340, 42561/42562), MAC blocks 40014/40018, int8 RSSI 41046 and 41048 (declared uint16, spans two registers). Battery 2 power is omitted deliberately: the sheet prints 41150, but the community smartfox-modbus library (github.com/sim-san/smartfox-modbus, README \"Known datasheet corrections\") says reading 41150 desynchronises the link and the value is at 41441; battery 2 state of charge (41440) is kept. Heat pump thermal energy 41506 is omitted: the sheet says \"double\" but only two registers fit before 41508 and the same library reports a float32. WLAN polling is not supported - use the LAN interface."
