Dynamic EV charging BMW Connect

Energy
1

Hello to the community! I would appreciate some help to check yaml code.

I am trying to use HA to create a dynamic charging automation for my BMW i4 using the BMW Connect integration.

I live in Belgium in Flemish region. Over here the final price of electricity is influenced by the peak electricity consumption. For this reason, I would like to keep my total drawn from the grid at max 2500 W.

I have an EV charger that I cannot control. My car charging can be controlled through BMW Connect. When no limit is applied, the car is using more than 7kW.

Using BMW Connect, I can limit the Amperes from 0 to 32. The automations below were intended to do the following (but ID 001 is not working):

ID 001
When the car is connected to the EV charger (binary_sensor.i4_m50_charging_status_2) AND the Override button is off (input_button.override_ev_charging)
Should change the A (sensor.i4_m50_ac_current_limit) to keep electricity from the grid bellow 2500W

ID 002
Should change the A limit to 32A when I disconnect from the charger

ID 003
Should Override ID 001 in case I need to get max charging speed

Any help really appreciated

This it the code from my automation.yaml
