I am going to be fitting soffit down-lighters to the outside of my house (bungalow) soon but was just wondering, is it possible to fit Hive GU10 bulbs to them and control them from the app and set up schedules? If so, would that be a better idea than complete units? I would like them to be on some sort of dusk to dawn timer but just thought maybe hive bulbs would be a better option. Also, can they be grouped so they would all go on/off at the same time?
