Refurb Belkin WeMo Switch, $15

If you have any lamps or appliances you wish you could control from afar, Belkin’s popular WeMo Switch is marked down to just $15 today, if you don’t mind buying a refurb.

All you have to do is plug one of these in between a wall outlet and the device of your choice, and you’ll be able to turn it on or off from your smartphone or Amazon Echo, create automatic schedules, and even tie it to IFTTT recipes. For example, you could program your lights to come on when you pull into the driveway, or turn off when your Nest thermostat detects that you’re not home.
