In short: Tailwind iQ3 is a new garage door opener that makes your garage smart. Simply install this on your garage door, and you'll be able to use the app to open or close the garage as well as your voice, via Amazon Alexa. Additionally, the Tailwind iQ3 is able to control multiple garage doors. So if you have a multi-car garage with multiple doors, you can control all of them with the Tailwind iQ3. According to Tailwind, this works with garage door openers from Chamberlain, Chamberlain MyQ, Liftmaster, Genie, Wayne, Dalton, Sommer and many more. You'll want to check out their site to make sure your garage door opener is compatible.
Background: Just about everything is smart these days and can be controlled with your smartphone or your voice. And now your garage can as well. This is one of the more interesting features for a smart home, as you can be sitting in your car and drive down the street, then tell Alexa to open the garage, without having to press a button. Sure it's pretty easy to press that button, but now you don't even need to do that. You can also set up all sorts of alerts for this and get the door to open by itself as well, when you get nearby, using IFTTT.
The impact: This is going to make it easier for users to control their garage door opener, and they won't even need to worry about leaving their garage door opener in their car at night – which could get stolen, and they would have access to your home. Seeing as the app is on your phone (which you likely always have with you), or you are using Alexa, with a complicated command (because it needs to talk to the Tailwind skill), so it's less likely that people will be able to break in.
