Delay in the blind angle action and the retreived illuminance value

edit

Hello, Im trying to couple energyPlus with python using pyenergyPlus im applying actions on the slat angle of my interior blind and im retreiving its corresponding illuminance Current Code Logic:

I retrieve the current blind angle using: sa = cs = self.api.exchange.get_variable_value(state, self.blind_status_value) or 0
I alternate between two angles (180° and 60°) using: slat_angle = 180 if self.slats_state else 60
I set the new angle with: self.api.exchange.set_actuator_value(state, self.a_slats, slat_angle)

The Issue: When I run the code, the illuminance values I'm getting correspond to the previous angle setting rather than the current one:

When I set the slat angle to 60°, I get the illuminance value that should correspond to 180°
When I set the slat angle to 180°, I get the illuminance value that should correspond to 60°

i triend all the callbacks for now im using this one to send actions : callback_begin_zone_timestep_before_init_heat_balance and this to retreive the illuminance values :callback_end_zone_timestep_after_zone_reporting and my timestep is 1

My Hypothesis: I suspect this might be a timing issue where the system needs time to process the angle change before the illuminance measurement reflects the new setting
