Amazon has the Switchmate Snap-On Instant Smart Light Switch at a great price plus free Amazon Prime shipping.
Remember Switchmate, the easiest way to transform your non-smart switches (even the toggle ones) to a smart one? It's a portable lighting switch that you place over your old switches to make it work. Well, they have added a voice-activated feature. It's now called the Switchmate Voice-Activated Smart Lighting Toggle Switch.
The new switch works with Google Assistant and Wink Hub 2 and can also be activated via the timer, proximity sensors or your smartphone. You can automatically turn the lights on or off when you arrive or leave. With timers, you can program them to work on their own, even while you're away from home. With Switchmate, it's just snap and tap and you can enjoy automated lighting at home.
