Seeed Studio XIAO 2-Channel Wi-Fi AC Relay

Description

Seeed Studio XIAO 2-Channel Wi-Fi AC Relay is a compact smart home relay module built around XIAO ESP32-C3 for safe and flexible mains switching. This 2-channel Wi-Fi relay gives you independent AC control for two loads, built-in power monitoring, and direct compatibility with ESPHome relay control workflows, making it a practical option for retrofitting existing appliances and building a reliable Home Assistant relay module.

Because this Seeed Studio XIAO 2-Channel Wi-Fi AC Relay is pre-oriented toward Wi-Fi automation and energy visibility, it works well for lights, fans, sockets, compact appliance control, and distributed room automation. If you want a 2-channel Wi-Fi relay that can act as a smart home relay module with local control and metering, this board gives a much cleaner starting point than piecing together a relay, MCU, and power sensing circuit yourself.

Wiring Layout: The biggest practical question with a 2-channel Wi-Fi relay is always how it lands in a real installation. This Seeed Studio XIAO 2-Channel Wi-Fi AC Relay keeps the terminal layout clear, which makes it easier to integrate into a smart home relay module workflow without turning the installation into guesswork.

Hardware Positioning: With XIAO ESP32-C3, dual relays, metering, and Wi-Fi automation support in one enclosure, this board is positioned more like a finished Home Assistant relay module than a bare developer relay. That makes it useful for practical room-by-room deployments as well as prototyping.

Deployment Direction: If your goal is ESPHome relay control, local energy tracking, and external wall-switch input, this board packages those needs into a simpler path than assembling multiple modules yourself.

FAQ

Q: What is the main purpose of this board?
A: It is a 2-channel Wi-Fi relay for switching two AC loads while also supporting metering and ESPHome relay control.

Q: Is this suitable for Home Assistant?
A: Yes. This board is well suited to a Home Assistant relay module workflow, especially if you want local Wi-Fi automation with power data.

Q: Why choose this instead of a generic relay board?
A: A generic relay board usually lacks integrated metering, Wi-Fi automation focus, and a compact enclosure. This smart home relay module brings those together in a cleaner package.

Q: Can I use physical switches with it?
A: Yes. The board supports external switch control, which is helpful for pairing manual inputs with smart automation logic.
