+### Scene Channel

+The bridge itself supports a channel to activate scenes:
+
+| Channel Type ID | Item Type | Description |
+| --------------- | --------- | ----------- |
+| scene             | String             | This channel activates the scene with the given ID String. | 
+
+The scenes are identified by an ID String that is assigned by the Hue bridge. These must be aquired directly from [Hue REST API](https://developers.meethue.com/develop/hue-api/).
+
+This channel can then be used in the sitemap, for example as a switch or selection.
