This is an interesting development that no one was expecting. TheInformation.com and EVLeaks have confirmed that Google is working on an internet connected thermostat (similar to the Nest).
The current rumour says Google is developing the software and backend controls but the actual device will be developed by a third party. It is also expected to work on Android and IOS.
It is exciting to think of what Google may be able to do combining a WIFI thermostat with their huge cloud number crunching AI.
