With Senic Gira Friends of Hue wall switches, you can also turn Philips Hue smart lights on and off with a regular wall switch. When you turn off a regular light switch, your Hue light no longer gets any power, so they stop working. This isn't the case with the Senic light switch. The switch looks like a normal light switch, it's completely wireless, and works without batteries. It charges by motion energy when you press the button. The Senic Friends of Hue products integrate seamlessly into the Philips Hue app after you connect them to your Philips Hue Bridge.
