Kasa 3-way Smart Light Switch | $18 | Amazon
If you’re rewiring the lights in your home with smarts, Kasa switches are some of the best products for the job. This 3-way light switch by TP-Link is down to $18, a $7 discount. This is a Wi-Fi-enabled three-way switch, meaning you can install one of these in an existing system using a secondary light switch. Kasa’s switch works even with an ordinary switch on the other end, so you only need to buy one for net-connected lighting.
With it, you can set up lighting schedules, turn them on and off at will, and use Alexa or Google Assistant voice commands to control everything without lifting a finger.
