During the AMA on 5-7-'22, someone asked if there is gonna be a “Dim all lights in a Room” card.
Just in case that person also reads this forum: The App Device capabilities (Apparaat mogelijkheden) has the functionality to set devices in rooms based on there capabilities.
Just use the “Set [[capability]] to [[percentage]] in [[zone]] including subzones ([[subzones]])” card.
