Seeed XIAO 6-Channel Wi-Fi 5V DC Relay (ESP32-C6)

The Seeed XIAO 6-Channel Wi-Fi 5V DC Relay is a compact smart relay board designed to control six independent devices (10A 30VDC max recommended). Powered by the XIAO ESP32-C6 (pre-soldered to the module), it supports Wi-Fi, Bluetooth, and Zigbee, allowing flexible integration into a wide range of smart home systems. It is fully compatible with Home Assistant (via pre-installed ESPHome firmware) and requires no additional hub. You can manage each relay channel independently, monitor status in real time, and configure local or cloud-based control—ideal for low-voltage automation such as lighting, fans, and pumps. Two Grove interface ports are also onboard for adding additional sensors or actuators. The module comes in a 3D printed enclosure (PLA), which is also available on Thingiverse if you would like to print your own in a different colour filament or make customisations. Note: A USB-C cable is required but not included. Features
