With the Philips Hue Wall Switch Module Duo Pack, you can make 2 old-fashioned light switches smart. Do you still regularly use the old-fashioned light switch with your Philips Hue smart lights? Your smart lights don't work anymore, because they don't receive any electricity. The Philips Hue Wall Switch Module is a solution. You place this module between the wall switch and your lighting. You can turn the lamp off with the wall switch in the future, but also still turn it on with the app or voice assistant.
