So you just booked a vacation and are super stoked about relaxing for a couple of weeks on your trip. You are busy packing and planning for your weekend; maybe you're getting your kids and their belongings corralled. The last thing you need is the worry of forgetting something important-- perhaps something that could cost you a lot of money by the time your vacation is over. What if there was a way for your Nest thermostat to automatically know when you are leaving for vacation?

How it works

We have created an algorithm that will be able to determine when you are leaving out of town by utilizing the Gmail API and extracting your flight information automatically. Once we determine the dates that you are gone for, we command our Nest thermostat to execute the best money-saving action depending on your region for while you're gone. We have integrated a weather API that will determine the surrounding temperature and determine if turning off the HVAC system or setting the temperature to a minimum/maximum value is the most optimal solution to save costs.

For instance, in colder areas, we wouldn't want the HVAC system to completely turn off but instead maintain the lowest temperature so that the water pipes don't freeze while you're gone. Also, right before you return home, it automatically turns the thermostat back to normal so you can come back to comfort. We have also integrated a cost saving calculator to the main Nest Home UI that will show how much you have saved!

Finally, for additional peace of mind, we integrated the Twilio API to text you once our algorithm activates so that you can be absolutely sure everything's fine!

Challenges I ran into

The getting started section of the NEST API wasn't the most user friendly. We also had a hard time parsing the emails for flight information.

Accomplishments that I'm proud of

We have implemented an app not previously featured on the Nest websites best apps. This is a very real use case and we hope will encourage more integration with google services.

What's next for Nest Vacation Saver

With the release of Google Now, we can use the more user friendly Now Cards to infer flight information and more seamlessly update information across services
