Home Depot offers the second-generation Samsung SmartThings Hub for $79.98 with free shipping. (Amazon charges the same.) That's tied with our mention from two weeks ago and the lowest price we could find now by $20. The hub allows you to connect all of your smart locks, lights, outlets, and thermostats and control them with your smartphone via the free SmartThings app. It's compatible with iOS, Android, and Windows Phone.

Update: Dell Small Business now charges the same.
