How to adjust battery charge power on a Sigenergy system

Hi

I’m controlling a Sigenergy system via Home Assistant using the Sigenergy ESS integration. I’m trying to limit the “maximum battery charge power”.

Activating and disabling discharging to the grid works fine. Charge limiting doesn’t.

I tried setting:

number.sigen_plant_ess_max_charging_limit

The value changes fine in Home Assistant, no errors, but the battery still charges at full power.

This works perfectly when I set the max charge power in the Sigenergy app.

Questions:

-Is number.sigen_plant_ess_max_charging_limit actually meant to work?
-Is there another entity that controls max charge power?

Anyone had success doing this?

I have the same issue. AI search seem to hint others are seeing the same problem. Will post if I find a solution but suspect a bug somewhere…
