Matter is a new smart home protocol launched by Amazon, Apple, Google, and a host of manufacturers to eliminate incompatibilities between smart homes. Matter incorporates many of the benefits of HomeKit, such as a superb security protocol and a completely local architecture – no network connection is required at all. If you are an iOS user, you can use matter in almost the same way as HomeKit, simply by using the home app to do all the pairing and control. Since Matter is an open protocol, there will be a wider variety of products available on the market.
