Dynamic Zero Export with the SUN-M80G4-EU

[mgherzan]

Knowing that "write holding registers" works at least to some extent, does anyone know if:

1. The AC output power can be limited though such a write command?
2. Assuming a positive answer to the previous question... would this enable a dynamic zero-export automation logic, relying e.g. on a Shelly 3EM to measure the power drawn by the home?
