Self-Hosted Home Dashboard Server Kit with ESP32 + DHT22
Self-Hosted Home Dashboard Server Kit — ESP32, DHT22 & Relay Control Without the Cloud
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Picture a dashboard that shows live temperature, humidity, and pressure from two rooms, controls four appliances, logs data to an SD card, and runs completely on its own Wi‑Fi network — no router, no cloud, no monthly fees. This kit gives you the hardware and AI guidance to build exactly that: a self‑hosted ESP32 web server that turns sensor data into real‑time charts and lets you flick relays from any device on the local network, even when the internet is down.
What You'll Build
You’ll assemble and program a standalone dashboard server that hosts an interactive web interface. Two DHT22 sensors capture temperature and humidity from separate zones, the BMP280 adds barometric pressure, and the DS3231 RTC timestamps every reading. Relay outputs let you toggle fans, lights, or pumps directly from the dashboard, while the MicroSD module records sensor history for long‑term analysis. The entire system boots in AP mode, so you connect your phone or laptop to its Wi‑Fi and open the dashboard in a browser — no internet required.
What You'll Learn
- Programming an ESP32 as an asynchronous web server with WebSocket live updates
- Reading digital and analog sensors (DHT22, BMP280) and calibrating data
- Building server‑side charts using CanvasJS or Chart.js served from SPIFFS
- Implementing relay control logic with fail‑safe states and logging to MicroSD

Who This Kit Is For
Engineering students — especially B.Tech ECE, EEE, and CS branches at IITs, NITs, VIT, BITS, and state universities — who want a capstone project that demonstrates embedded systems, networking, and full‑stack development. Smart India Hackathon teams working on off‑grid monitoring or home automation prototypes. ATL Tinkering Lab coordinators guiding advanced senior‑secondary students (CBSE Class 11‑12) through a self‑contained IoT infrastructure. Anyone building a resilient home dashboard that stays up when the ISP goes down.
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 open the AI companion, which walks you through each wiring stage and code block. If you need human help, message us on WhatsApp — we typically reply within an hour during Indian business hours.
Does this kit require an internet connection to work?
No. The ESP32 creates its own Wi‑Fi access point; you connect directly to it and access the dashboard at a local IP address. The entire sensor‑logging and relay‑control system runs offline.
Can I control mains‑voltage appliances with the relay module?
The 4‑channel relay module can switch AC loads up to 250V 10A. You’ll need to wire the high‑voltage side safely, and we strongly recommend using the enclosed PCB prototype board to isolate the low‑voltage ESP circuit from the relay contacts.
What if I want to extend the dashboard later with more sensors?
The code architecture uses modular sensor handlers, so you can add I²C or one‑wire sensors by editing a few lines. The AI companion includes examples for adding a PIR motion sensor or an OLED display.
ESP32 runs a complete web server with charts, sensor readings and relay control. No internet required.
