Wine Cellar Climate Monitor Kit with ESP32 + DHT22
Wine Cellar Climate Monitor Kit with ESP32-H2 – Bring Your Wine Storage into Apple Home & Google 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.
For any serious collector, fluctuating temperature and humidity can spoil a rare bottle. This kit lets you build a Thread-based climate monitor that seamlessly integrates with your existing Apple Home or Google Home setup, providing real-time alerts and automatically switching cooling relays to maintain perfect cellar conditions.
What You'll Build
You'll assemble a compact, mains-powered sensor node that reads ambient temperature and humidity via a calibrated DHT22, triggers dual relays to manage a wine cooler or humidifier, and exposes everything as a native Matter accessory — no extra hubs beyond a Thread border router. The finished unit mounts inside your cellar, connecting wirelessly to your smart home network for real-time monitoring and automations.
What You'll Learn
- Commission an ESP32-H2 as a Matter Thread end device and integrate it with Apple Home and Google Home
- Calibrate and place a DHT22 for accurate cellar-grade temperature/humidity logging
- Design a relay control circuit to switch wine cooling appliances based on sensor thresholds
- Solder a permanent prototype on a PCB board and package it in an enclosure for long-term deployment

Who This Kit Is For
Engineers and technology professionals passionate about smart home automation who want a sophisticated Matter project. It's also ideal for B.Tech ECE/EEE students building an advanced prototype for Smart India Hackathon or a final‑year project on IoT-enabled precision storage. Wine collectors and cellar owners in India who value native Apple/Google integration get a reliable, self‑built solution tailored to their specific environment.
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?

Do I need a Thread border router?
Yes, to add the sensor to Apple Home you need a HomePod mini, Apple TV 4K, or similar; for Google Home, a Nest Hub (2nd gen) or Nest Wifi Pro works.
How accurate is the DHT22 for wine cellars?
The DHT22 provides ±0.5°C accuracy and ±2% RH, sufficient for most home wine storage conditions. Calibration is explained in the AI companion.
Can I use this with an Indian wine cooler?
The relay outputs are voltage-agnostic and can interface with any cooling unit that accepts a dry contact or low-voltage trigger, common in Indian‑market coolers.
Wine Storage — ESP32-H2 Thread node bridges Zigbee and WiFi devices exposing them as Matter accessories to Apple Home and Google Home.
