Developed by Apple, Amazon, Google, and Samsung (and others), Matter is an open-sourced, IP-based connectivity software layer for smart home devices. It works over Wi-Fi, ethernet, and the low-power mesh networking protocol Thread and currently supports over 30 device types. These include lighting, thermostats, locks, refrigerators, dishwashers, dryers, ovens, smoke alarms, air quality monitors, EV chargers, and more.

A smart home gadget with the Matter logo can be set up and used with any Matter-compatible ecosystem via a Matter controller and controlled by them simultaneously, a feature called Multi-Admin.

Amazon Alexa, Google Home, Samsung SmartThings, and Apple Home are some major smart home platforms supporting Matter, along with hundreds of device manufacturers.
