Matter Bridge 20 Device Network Kit with ESP32 + Relay
ESP32 Matter Bridge Kit: Expose 20 Real Sensors and Relays to Apple Home
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your ESP32 into a powerful Matter bridge that translates real-world sensor data and relay states into 20 virtual smart home accessories on Apple Home. Control lights, monitor temperature and motion across your home, all from your iPhone. This kit equips you with every component, a detailed build roadmap, and an AI companion that knows this exact project inside out.
What You'll Build
You'll assemble and program an ESP32-based Matter bridge that creates 20 device endpoints in Apple Home. These endpoints map to the physical sensors and relays in the kit, allowing you to monitor temperature, detect motion, and switch appliances remotely. The bridge ensures seamless communication between your physical hardware and Apple’s smart home ecosystem.
What You'll Learn
- Implement the Matter protocol on ESP32 using the official Arduino Matter library
- Map physical GPIO pins to virtual device endpoints for sensors and relays
- Calibrate and integrate multiple DHT22 temperature/humidity sensors and HC-SR501 PIR motion detectors
- Design a protected power circuit using buck converters and flyback diodes

Who This Kit Is For
This kit is built for B.Tech ECE/EEE students tackling IoT protocol projects, Smart India Hackathon teams prototyping home automation solutions, and advanced hobbyists from institutions like IIT, NIT, VIT, and BITS who want hands-on Matter experience. If you’ve already built basic Arduino projects and want to master cutting-edge smart home standards, this is your next challenge.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion trained specifically on this kit. It provides step-by-step debugging, and you can also reach us on WhatsApp for human support.
Does this kit require an Apple device to work?
Yes, the Matter bridge exposes devices to Apple Home, so you need an iPhone, iPad, or Mac with the Home app to see and control the virtual devices. However, the ESP32 can still function as a standalone sensor network without Apple Home if you reprogram it.
Can I add more than 20 devices?
The Matter bridge firmware is designed for 20 endpoints by default. You can modify the code to support more, but it requires advanced ESP32 memory management and may impact stability.
Is the enclosure included ready to mount?
The kit includes a standard plastic enclosure box with mounting slots. You’ll need to drill holes for sensor wires and relay terminals; a template is provided in the build guide.
ESP32 Matter bridge exposes 20 virtual devices to Apple Home. Each device maps to a real sensor or relay.
