Our Seeed Studio XIAO ecosystem has been growing steadily with tap-on accessories like Grove Expansion Boards, Sensors, Connectivity Modules, and Actuators to complement our thumb-sized dev boards. But one thing kept coming up in our XIAO Open Roadmap – you wanted more relays! Well, we heard you, and here’s our answer: the new Seeed Studio 2-Channel AC Wi-Fi Relay.

Powered by our thumb-sized XIAO ESP32C3, this Home Assistant-native relay device lets you control two independent 100-240V AC loads – perfect for lights, appliances, and motorized facilities. We’ve pre-flashed it with ESPHome firmware and built in a power meter, so you can track both real-time and historical power consumption right from your Home Assistant dashboard. 

All the above-mentioned features make it particularly suited for applications that need both remote control and power monitoring of household electrical devices through a smart home automation system.

Want to know what’s under the hood? We’ve packed in two 10A/250VAC high-power latching relays (HF3F-L), giving you control over two loads on a 50-60 Hz AC carrier signal. Here’s a sneak peek at the internals – and don’t worry, we’ll be open-sourcing all schematics on our Wiki soon!

Ready to get your hands on one? The Seeed Studio 2-Channel AC Wi-Fi Relay is available for pre-order at our Bazaar webstore for just $19.90. Shipping starts in early January 2025, and it’ll also be available on our AliExpress and Amazon stores.

Oh, and one more thing! The relay comes in a white 3D-printed enclosure (which you can download and customize from Thingiverse for free). And for all you makers and developers who want to DIY with your existing XIAO boards – stay tuned! We’re working on a universal Relay Add-on that’ll be compatible with all XIAO dev boards. 🤫🤫
