Wine Cellar Climate Monitor Plus Kit with ESP32 + DHT22
Wine Cellar Climate Monitor Plus Kit – ESP32 Matter Control with DHT22 & Relay
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Monitor and control your wine cellar’s climate from anywhere using a single Matter-certified ESP32 that connects natively to Apple Home, Google Home, and Amazon Alexa — no third-party bridges or cloud subscriptions. The DHT22 tracks temperature and humidity precisely, triggering a relay to activate a cooling unit or dehumidifier the moment readings stray outside your preset thresholds. An OLED display gives you at-a-glance readings right inside the cellar, while your phone app delivers alerts and control no matter where you are. This kit transforms a weekend build into a professional-grade cellar guardian.
What You'll Build
You’ll assemble a standalone climate monitor that permanently tracks temperature and humidity inside your wine storage. When conditions deviate from custom-defined safe ranges, the device switches a relay to start or stop connected cooling or humidity control equipment automatically. The finished unit fits into an enclosure box, mounts discreetly, and reports real-time data through Apple Home, Google Home, or Amazon Alexa using the latest Matter protocol.
What You'll Learn
- Programming ESP32 with Arduino IDE and the Matter SDK to create a cross-platform smart home accessory
- Wiring and calibrating a DHT22 sensor for laboratory-grade humidity and temperature accuracy
- Controlling a 5V relay module safely to switch high-power appliances without disrupting the microcontroller
- Designing a 5V/3.3V power supply with an LM2596 buck converter and soldering it onto a prototype board

Who This Kit Is For
Wine collectors who want a no-cloud-required, app-optional climate monitor will find this an elegant DIY solution. B.Tech ECE and EEE students tackling IoT capstone projects or final-year design labs can leverage native Matter integration for cross-platform demonstrations. Professionals prototyping for Smart India Hackathon or smart agriculture challenges will appreciate the kit’s instant Apple, Google, and Amazon compatibility out of the box.
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 talk to the AI companion that knows every connection of this kit; if you need human help, WhatsApp us directly from the same interface.
Do I need an Apple HomePod or other hub to use Matter?
Yes, controlling the monitor via Apple Home requires a HomePod, Apple TV, or similar Matter border router. Google Home and Amazon Alexa setups need their own compatible hubs, but the ESP32 firmware works with all major ecosystems once paired.
Can I add a second sensor or control another appliance later?
The ESP32 has spare GPIOs and the AI companion can guide you through expanding the circuit; additional modules are not included but the prototype board has room to grow.
Is the included soldering iron suitable for this project?
Absolutely — the soldering iron and solder wire are selected for the through-hole work on the prototype board, making it straightforward even if you’re building this as your first serious soldering project.
Wine Storage — ESP32 Matter SDK device exposes temperature and relay to Apple Home, Google Home and Amazon Alexa natively.
