Modbus for Huawei EMMA

[ConstantinOWORX]

Hi,

Huawei has introduced last year a new backup box called SmartGuard.
This new SmartGuard, comes with a new management system called EMMA.

The problem is that EMMA takes over the Inverter management and we need to remove the SmartDongle in order for the system to work.
EMMA does support Modbus over TCP but of course has different mappings.

Would it be possible to add support for EMMA in the future?

Hi, We can do it if works over Modbus TCP.

First I need the modbus registers for EMMA device, and be able to connect to your EMMA device in order to test it.
