With the update to version 5.19 of its app, Philips Hue has introduced several new functions, including the ability to combine several motion sensors into a group. For another new feature, however, I had to do some more research: “Start a ‘Go to sleep’ automation not only in the app, but also by pressing a button on a Hue switch or an iOS widget.”
Sleep automation: Not yet available for all switches So far only for the Hue Twilight
