EasyMatter is an Arduino C++11 wrapper by thegraywaver, published on GitHub, that sits on top of Espressif’s official Arduino Matter endpoints. It does not implement Matter itself and does not invent endpoint types. The current code targets the original ESP32-WROOM-32 with the Espressif Arduino-ESP32 Matter build.

Set config.deviceType before begin() , and the library creates the matching Espressif endpoint, starts Wi-Fi from supplied credentials, starts Matter, and prints the manual pairing code and a scannable QR code in the Serial Monitor. Temperature plus humidity creates two endpoints on the same node.…
