A smart light switch adds control to one of the connected home's most basic functions, and today, you can add one of your own for cheap--the WeMo light switch is on sale for $35 on Amazon, down from a list price of $50. This light switch is designed to add convenience and control to your home lighting. You'll be able to make adjustments and commands from your phone via the WeMo app, but you can also connect it to your other smart devices to add voice control with Amazon Alexa or the Google Assistant. If you know when you'll be around, you can schedule when your lights will come off and on, or randomize when you're away to deter potential intruders. And it doesn't have to be lights--connect this switch to a ceiling fan or anything else controlled by a one-way connection light switch and you'll be able to control that as well.
