TIL: Matter is the smart home protocol that finally delivers cross-manufacturer compatibility. Backed by Apple, Google, Amazon, and Samsung, it uses IPv6 over Thread/WiFi. A Matter-certified device works with HomeKit, Google Home, AND Alexa - no more choosing ecosystems.


```javascript
// Matter device interoperability
const device = new MatterDevice('smart_bulb');

// Same device, multiple ecosystems
device.expose([
  HomeKitBridge,
  GoogleHomeBridge, 
  AlexaBridge
]);

// Local control without cloud
device.onLocalNetwork(threadNetwork);
// Works even if internet is down
```
