Server Room Temperature Monitor Kit with ESP32 + DHT22
Server Room Temperature Monitor Kit with ESP32-H2 — Matter-Enabled for Apple Home & Google Home
Every part needed to build a Matter-connected temperature monitor for your server room, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When a server room overheats, critical equipment fails and downtime costs mount. This kit gives you everything to build a rugged temperature monitoring system that speaks Matter, appearing instantly in Apple Home and Google Home. The ESP32-H2 acts as a Thread node, bridging local sensor data and relay control to your existing smart home ecosystem — no cloud subscriptions, no vendor lock-in, just reliable monitoring for data centres and co-location racks across India.
What You’ll Build
You’ll assemble a wall-mountable unit with a precision DHT22 sensor measuring temperature and humidity, and two independent relay channels for controlling exhaust fans, air conditioners, or alert sirens. The device exposes itself as a Matter Temperature Sensor and two Matter Switch accessories, so you can set automations like “if temperature exceeds 35°C, turn on the cooling relay.” The solid enclosure keeps everything rack-ready, and the buck converter ensures stable 5V power from a standard USB-C supply.
What You’ll Learn
- Programming ESP32-H2 for Zigbee-to-Matter bridging with the ESP-IDF
- Reading and calibrating DHT22 sensor data with resistor-capacitor filtering
- Soldering through-hole components onto a prototype PCB
- Wiring a buck converter to regulate USB-C power for the board and relays

Who This Kit Is For
Data centre technicians and IT managers who need a reliable, Matter-native monitoring solution for server racks. B.Tech ECE final-year students building IoT capstone projects on smart infrastructure. Smart India Hackathon teams working on industrial automation. Anyone responsible for a server room in a co-location facility, edge data centre, or institutional server closet who wants alerts in Apple Home without a proprietary hub.
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 inside the box to chat with our AI companion trained on this kit. If it can’t solve the issue, we’ll jump in over WhatsApp within hours.
Can I integrate this with existing Zigbee sensors in my server room?
The ESP32-H2 can act as a Zigbee-to-Matter bridge, so you can bring third-party Zigbee temperature sensors into Apple Home alongside this unit. We provide example firmware to get you started.
Does this need a separate Thread border router?
It works as a Thread End Device, so you’ll need a Thread border router like an Apple TV 4K or Google Nest Hub in range. The ESP32-H2 can also be configured as a minimal border router if you’re comfortable with advanced ESP-IDF settings.
What kind of relay loads can it handle?
Each relay module is rated for 250V 10A AC or 30V 10A DC, enough to switch cooling fans, small air conditioners, or alarm sirens directly. For inductive loads, we recommend adding a snubber circuit (not included).
Data Centre — ESP32-H2 Thread node bridges Zigbee and WiFi devices exposing them as Matter accessories to Apple Home and Google Home.
