(Pocket-lint) - Philips Hue overlord Signify has announced the upcoming launch of a Wall Switch Mount, allowing users to turn any light switch into one that's truly smart, rather than the lightbulb. The device solves one of the longest-serving problems within smart lighting: that is, if you install a smart bulb in a fitting controlled by a 'dumb' switch, turning off said switch effectively cuts the signal dead and the smart element is lost. Hue's latest gadget tackles this basic-but-crippling issue at the source, turning the receptacle into a wired-in smart switch that can still manage scenes and commands whether it's technically 'off' or 'on'.
