It is possible to add a command to recall a Philips Hue Scene. However, scenes are recalled by an ID, not a name, and I don’t know the IDs. The Hue iOS app that creates scenes does not appear to indicate the scene id, and the hue web app doesn’t show scenes or scene IDs.
Hi. Yes, I’d already done that. The manifest shows up as a series of lights. The default action can be used to turn each light on and off. But adding a scene recall activity for the hue bridge just yields a text entry field for the scene ID.
