To move an accessory to a room, you can do it either from the Room screen by selecting "Move accessories" action top button, or from a specific accessory settings page.

On a room main screen, the "Move accessories" button will be highlighted in blue when some accessories have not been moved to any room yet. If all accessories are already moved to a room, it will be inactive, and you will need to go to the specific accessory settings to move them to another room.

Note that when you move an accessory of a different type to a room, it adds some more information in the room settings and highlights the response the devices of the room will have when the accessories is used to control them.

You can also see those from the accessory settings page.

In the Room Settings page, you will see tabs detailing for Light control and sensor depending on the accessories present in the room.
