Google introduces Matter protocol for smart home devices, adds WebRTC support and more Google has announced 4 new updates to their smart home ecosystem that will improve the experience for users. These updates include two new protocols that will improve compatibility and user experience, improved Home & Away Routines, and the Google smart home directory. One of the new protocols introduced is called Matter, which was co-developed by Google and other tech companies. Support for Matter will be added to Android and Nest devices, and will enable simpler setup and interoperable control for Matter-certified products. The second protocol added is WebRTC, which will improve live video and audio-streaming experience by reducing latency between security cameras, video doorbells, smart displays and mobile devices. Some of the many manufacturers that will also support WebRTC include Arlo, Logitech, Netatmo and Wyze.
