SMA
ESS
Tested on - SMA SunnyIsland 6.0H - Sunny Island 4.4M - SMA Sunny Boy Storage 2.5 - SMA STP 10.0 Hybrid ESS. (The implementation is split into Battery, Inverter and DC Charger. The inverter only works with that battery, but the implementation had to be split up as the devices use different Modbus Unit IDs.)
The Sunny Boy Storage implementation uses the SMA BMS external control interface (CmpBMS). The control registers for BMS mode, min/max charge power, min/max discharge power and grid power setpoint must be written within every 60-second window or the device reverts to autonomous mode.
Meter
Tested on - SMA Sunny Home Manager 2.0 Integrated Meter
This implementation uses the integrated energy meter of the SMA Sunny Home Manager 2.0 Data needs to polled through Modbus from an attached SMA inverter as the HM2.0 does not have a local API on the device itself
