Home automation has become a pretty big business in the past few years. Belkin and Philips have been at the forefront of this with their WeMo and Hue brands, respectively. Belkin's WeMo brand has put out all kinds of great products, including smart light switches, smart bulbs and even smart outlets. Right now, their Insight Switch is currently on sale for just $35.95 at Amazon, and it's an absolute steal, given it's normal price is $59.99.
The WeMo Insight Switch connects to your smartphone via WiFi (and using the WeMo app). Additionally, you can set schedules for turning items that are plugged into the switch on or off. So if you have a lamp plugged in, you can schedule it to turn on when the sun sets and turn off when you head to bed around 11pm. The app from WeMo works with Android 4.1 and higher, which is used to control the switch. Additionally it works with any product that has an electric rating of 120V/15A/60Hz/1800W. Best of all, it's compatible with the Amazon Echo. Meaning you can turn these appliances or lamps on and off without having to use your phone. You can do it all with your voice. Talk about being convenient.
