Changing the max charging power in HA

[B-noob]

With one of the latest update in the sigenergy one can adjust the maximum of the charging power of the battery. For example, I may be able to reduce the max power, so that the battery gets charges slower (hoping to not stress the battery). On some days, I have plenty of power coming from the sun, so I do not need the 0.5C of the batteries to charge my batteries in 2h.

Now. with the HA intragration, I was able to change the MAX SOC with the entity number.sigen_plant_ess_charge_cut_off_state_of_charge

I was hoping to adjust the maximum power for charging with the entity number.sigen_plant_ess_max_charging_limit. The number given in the entity is 0,0. When entering any number, such as 2,0 or 2.0, the following error is shown.

Die Aktion number/set_value konnte nicht ausgeführt werden. Error writing registers: Error writing registers at address 40032: ExceptionResponse(dev_id=247, function_code=144, exception_code=2), ExceptionResponse(dev_id=247, function_code=144, exception_code=2)

What do I do wrong?
Does anyone know?

Thanks

Try again but activate "Remote EMS" and set mode in "Command Charging" before changing the value.
If you still get errors, please open a issue and attach logs and diagnostics as instructed in issue creation wizard.

Thank you, that did the trick. However, while the changes in the SOC are alos updated in the app, the changes of the set numbers in the charging power is not updated in the app. Nevertheless, it works and changes in HA are implemented. Thank you so much for your work and for your quick response/help

I believe the restrictions are applied at different levels and you won't see the restrictions in the app.
