I use the Friends of Hue but left physical switches (in the on position) under them. So if you pull them open you can turn off the power in an emergency.

And 3d printed a holder for a few rooms that fits the Gira frame and holds a Hue button. Works to control more things (and used it that way in my old house), but the color of Hue isn't exactly the same as the frame.
