A:Answer The number of switches in the gang bank is not an issue. The main thing you know is how many switches control the light. For example, if there is a light at the top of the stairs, and a switch that controls it at the top and bottom of the stairs, your Switch+ won't work. Keep in mind of course that any of the Hue-specific features such as dimming/lighting colour will not be controllable from the physical Switch+ unit.
The dimensions are --
Switch+ measurements:
Length: 106 mm
Width: 45 mm
Depth: 50 mm
--
Wall plate measurements:
Length: 119 mm
Width: 75 mm
Depth: 7 mm
--
As well, if the Alexa account linked to the Switch+ also has the Hue skill enabled, you can control the light strips via voice commands to the Switch+. Hope this helps!
