SwitchC6 Home Assistant Integration

Introduction

SwitchC6 is an IoT single-live wire switch controller. It integrates the ESP32-C6-MINI-1 core controller and a magnetic latching relay, supports connecting to electrical load circuits of AC 100 ~ 230V, and helps quickly build IoT smart homes. The controller comes pre-installed with ESP-NOW control firmware, and provides related control protocols and SDKs, allowing users to wirelessly control it with any ESP32 device. The back adopts a rail clip design, making it easy to install on DIN rails, suitable for embedded smart home control, upgrading single-live wire lighting circuits, and other application scenarios.
