The Nest is a smart and self-learning thermostat device for your home's heating and cooling systems.
The Nest.com Web application lets you control your thermostat remotely and see recent climate and heating/cooling schedules. However, this data is only kept for a relatively short period of time on their site.
This app lets you extract data from Nest.com's web application and feed it into Splunk for long-term storage and reporting!
