You can save more than one item of Somfy RTS equipment on the same radio channel to create groups of equipment.
All equipment configured on the same channel then functions together.

When you are asked to select an already occupied channel, choose the chennel where you want to group your RTS equipments.
It is recommended for optimum ergonomics, to group all equipment of the same type together on a single radio channel. However, if the equipment that you add is not of the same time (e.g: adding a roller shutter to a channel occupied by a lamp), the pictogram of the last added product (roller shutter) shall be given precedence. It is nevertheless possible to change the name of the channel (e.g.: "Lights" can become "Living room").
