Pi Zero W MQTT Relay Node Kit with Raspberry Pi Zero + Relay
Pi Zero W MQTT Relay Node Kit – Build a Remote IoT Controller with Raspberry Pi Zero W and Node-RED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Take your first step into wireless home automation. With this kit, you’ll configure a Raspberry Pi Zero W as an MQTT subscriber that listens for commands and switches two 5V relays – ideal for controlling lights, fans, or lab equipment from your laptop. Node-RED’s drag-and-drop interface makes the remote dashboard a breeze.
What You'll Build
A fully functional wireless relay node that sits on your home or school network, ready to accept on/off commands from any device running Node-RED. You’ll be able to control appliances, create schedules, and even integrate with dashboards – a solid base for your IoT portfolio.
What You'll Learn
- Configuring an MQTT broker and publish/subscribe topics
- Wiring a relay module with flyback diodes for safe Raspberry Pi GPIO control
- Building a Node-RED flow to send commands and display relay states
- Designing and testing a wireless IoT node for real-world switching applications

Who This Kit Is For
Ideal for CBSE Class 11–12 students preparing IoT-based physics or computer science projects, B.Tech ECE/EEE undergraduates building automation prototypes, and Smart India Hackathon teams needing a ready-to-integrate wireless node. ATL Tinkering Lab instructors will find it a structured way to teach MQTT and relay control.
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 to launch the AI companion trained on this exact Pi Zero W relay project. It answers questions instantly and offers step-by-step troubleshooting. If you need a human touch, reach out on WhatsApp – our team typically responds within an hour.
Can I control more than two relays with this kit?
The kit includes materials for two relays, but you can easily expand by adding more relay modules (sold separately) on unused GPIO pins. The MQTT logic remains the same.
What if my Wi-Fi network drops during operation?
The Pi Zero W will retain its last relay state. As soon as the network reconnects, it will re-subscribe to the MQTT broker and resume normal command reception.
Do I need to know coding to build this?
You’ll use Node-RED’s visual flow editor, which requires no traditional coding. Basic understanding of Raspberry Pi terminal commands (covered in the AI companion) is sufficient.
Pi Zero W subscribes to MQTT topics and toggles relay outputs. Node-RED on laptop controls remotely.
