Seeed XIAO 2-Channel WiFi AC Relay

Overview

The Seeed XIAO 2-Channel WiFi AC Relay is a compact relay module built around the XIAO ESP32-C6 microcontroller. It provides two independent AC relay channels with support for WiFi 6, Zigbee 3.0, and Thread protocols, making it a versatile building block for smart home projects.

Key Features

• ESP32-C6 with WiFi 6, Zigbee 3.0, and Thread/802.15.4 support
• 2 independent relay channels — each rated for up to 10A at 250V AC
• Compact form factor designed around the XIAO module ecosystem
• Compatible with Arduino, ESPHome, and MicroPython
• Built-in power supply — runs directly from AC mains
• Screw terminals for easy wiring

Getting Started

1. Flash the XIAO ESP32-C6 with your preferred firmware (ESPHome recommended for Home Assistant integration)
2. Wire the relay module to your AC loads using the screw terminals
3. Configure the two relay channels in your firmware
4. Integrate with Home Assistant or your preferred smart home platform

Firmware Options

• ESPHome — Recommended for Home Assistant users. Full support for both relay channels, buttons, and status LEDs
• Arduino — Use the ESP32-C6 Arduino core for custom firmware development
• Zigbee/Thread — The ESP32-C6 supports native Zigbee and Thread, enabling direct integration without WiFi

Safety Notes

• This module handles mains AC voltage — proper electrical safety precautions are essential
• Ensure adequate ventilation and do not exceed the rated current per channel
• Installation should be performed by qualified personnel where required by local regulations
