Roost is an application that allows you to manage your Nest devices using the nest.com service. Currently this is a wrapper to the nest.com site with some additional functionality. If Nest Labs give us access to the API we will create a native client that you can switch between. This app is not, associated with, endorsed by, or affiliated with Nest.com or Nest Labs, Inc. Supports small, medium, and large tiles. Live tiles coming soon. Adding and managing a Nest thermostat is supported. Please note that adding a Nest Protect smoke and carbon monoxide (CO) alarm is not supported at this time. Managing a previously added one is. This is a Nest limitation.
