Nest Open-Sources Thread
In 2014, Nest created an all-new wireless networking protocol with the intention of making the smart home, smarter.
Using the same frequency and radio chips as Zigbee, Thread enables low-power mesh wireless networks for up to 250 devices. The intention for the new protocol is to improve interoperability, lower the power requirements, and reduce hardware dependencies.
One of the biggest problems facing the smart home movement is creating a standard way for all connected devices in the home to communicate easily. Today Nest is making Thread available open-source, potentially a big win for developers focused on home automation and the smart home.
