Thank you, @jroberts!
This is expected. You have to use the enhanced in order to run a simulation for all the different states. If set to False it will still run, but only for the default state.
The sensor grids have a property called room_identifier. In order to link the aperture group to the grid, the room_identifier of the grid must be the same as the identifier. If you use HB Sensor Grid from Rooms the room_identifier is automatically set. If you create the grid manually, you can set the property yourself. This should be fine as long as you match the grids and rooms correctly. I have attached the example in the file.
