KNX PROS & CONS about using same device for sensor&actuator and impact on electrical design

Is there any recommendation to take into account about using devices that joins the sensor and the actuator instead of placing all the actuators in the electrical control panel? What are the pros and the cons?

In a new home unifamiliar building, is there any guideline to follow about this? I understand that in some cases you can save on electrical/bus wiring, but I have no idea when it could be better.

Thanks
