I think Signify (Philips Hue) is on the board of Matter.
Matter is a unifying platform for smart home products from Google, Samsung, Apple, Amazon and co. Matter is a unified system that will allow you to use your smart home devices with any assistant of your choice. Unlike most products that work with only one of either the Google Assistant, Amazon Alexa, or Apple Homekit, Matter-branded products can be configured to work with any one of them.
The Philips Hue Bridge smart lighting hub will be automatically enriched with Matter, making all connected Philips Hue products compatible with this new industry-unifying standard
"Within Philips Hue, we are always looking to provide our users with the latest innovative and enhanced connected experiences with other smart home systems. By actively participating in demos and testing the interoperability of Philips Hue with other smart home devices via Matter we were able to raise the smart home experience with Philips Hue to the next level. I believe this single, unified connectivity standard will transform smart home technology from an emerging technology to mass household adoption.” George Yianni Head of Technology Philips Hue at Signify
Matter is currently expected to be launched by the Connectivity Standards Alliance in the last quarter of 2021
