You will soon be able to see from your app what the ambient air temperature is at your SkyBell HD! This feature will only be available with SkyBell HD's.
All HD's have a temperature sensor built onto the board but the feature is not yet available in the app. When this feature is available it will be added with an over the air update to your SkyBell and the new feature will be added to the user interface with an app update. Facebook will first post when this feature is available!
