ESP32-C3 Zigbee Smart Bulb Emulator Kit with ESP32 + LED
Build a Zigbee Smart Bulb with the ESP32-C3 — No Proprietary Hub Required
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into the world of home automation without being locked into a single brand. With this kit you turn an ESP32-C3 into a fully functional Zigbee smart bulb that pairs directly with Zigbee2MQTT and drives a vibrant WS2812B LED strip — all from a custom-soldered board. It's the same technology commercial bulbs use, but fully open, hackable, and ready to integrate with Home Assistant, Node-RED, or any MQTT client.
What You'll Build
You'll assemble and program a real Zigbee smart light that appears as a dimmable, color-controllable bulb in your Zigbee2MQTT dashboard. The finished device can be mounted inside an E27 bulb shell or used as accent lighting, controlled wirelessly from your smartphone or voice assistant — no cloud dependency, no subscription fees.
What You'll Learn
- Soldering SMD and through-hole components onto a perfboard to build a functional Zigbee node
- Configuring the ESP32-C3 as a Zigbee end device using the ESP Zigbee SDK
- Integrating with Zigbee2MQTT and mapping device clusters for brightness, color, and on/off control
- Programming WS2812B LED animations with FastLED and orchestrating them via Zigbee commands

Who This Kit Is For
B.Tech ECE/EEE students who want a hardware project that demonstrates IoT protocols, Smart India Hackathon teams prototyping smart lighting solutions, and IIT/NIT/VIT final-year students preparing for placements with a strong embedded portfolio. It's equally suited for home automation hobbyists who refuse to pay for proprietary bridges and want full control over their Zigbee network.
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?
Open the AI companion from the QR code or message us on WhatsApp. It will walk you through diagnostics, code snippets, and hardware connections specific to this kit.
Can I control the smart bulb with Alexa or Google Assistant?
Yes, once the bulb is paired with Zigbee2MQTT and Home Assistant, the AI companion guides you through exposing the light to voice assistants via the Home Assistant Cloud or manual setups.
Do I need a separate Zigbee coordinator?
You’ll need a Zigbee coordinator like CC2652R or Sonoff Dongle running Zigbee2MQTT; it’s not included but our AI companion can help you pick the right one for your setup.
Is prior soldering experience required?
This is an advanced kit that involves soldering SMD components and through-hole headers. If you have basic soldering skills and patience, the step-by-step guide and videos will get you through it smoothly.
ESP32-C3 emulates a Zigbee smart bulb. Pairs with Zigbee2MQTT and controls WS2812B strip as light.
