WiFi Relay Power Switch
WiFi Relay Power Switch Kit – Control Any Appliance from Your Phone with ESP8266
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking into your room and turning on the fan or lamp just by tapping a button on your phone — no app, no hub, just a browser and your home WiFi. With this kit, you’ll build a WiFi relay power switch that plugs into any appliance and lets you toggle it on/off from any device on the same network. Perfect for smart home beginners, school projects, or adding voice control later.
What You'll Build
You’ll construct a compact circuit that connects an ESP8266 NodeMCU to a relay module, allowing you to remotely control lights, fans, or other low-power appliances. Once assembled, you’ll flash a ready-to-use web server onto the ESP8266 and access a simple toggle interface from your phone or computer. Your finished switch can be housed in a 3D-printed case or mounted behind a switchboard — it’s the foundation for countless smart home projects.
What You'll Learn
- How to wire a relay to a microcontroller and safely switch AC loads
- Programming an ESP8266 with Arduino IDE to host a web server
- The basics of WiFi-controlled IoT and HTTP requests
- Using diodes and resistors for circuit protection and indicator LEDs

Who This Kit Is For
Ideal for CBSE students looking for a working model for their physics or computer science project, ATL Tinkering Lab participants exploring IoT, and B.Tech ECE/EEE first-years who want a hands-on introduction to embedded systems. Also great for parents introducing their children (8+) to electronics with a project that has immediate, real-world impact.
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?
Our AI companion, accessible via QR code, guides you step-by-step. You can also reach out on WhatsApp for human support within 24 hours.
Can I control high-power appliances like geysers or ACs?
This kit is designed for low-power appliances (up to 5A at 220V) such as lamps, fans, and chargers. For higher loads, use an external contactor – our AI guide can help you design that safely.
Do I need to know coding before starting?
No prior coding is required. We provide the full code and a pre-configured Arduino IDE setup guide. You’ll learn as you upload and test.
Can I control the switch from outside my home network?
To access the switch remotely, you’ll need to set up port forwarding or use a cloud service. Our AI companion introduces optional MQTT-based extensions once you’ve mastered the local control.
ESP8266 controls relay from phone browser. Toggle any appliance on/off over home WiFi.
