Abstract

Microhomie is an open-source Internet of Things (IoT) project. MicroPython implementation of the Homie MQTT convention for IoT. Microhomie is a MicroPython framework for Homie _, a lightweight MQTT convention for the IoT. Main target for Microhomie is the ESP8266 device and has been well tested and used on ESP32. It is built using Python, MQTT, ESP8266, ESP32. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Microhomie is a MicroPython framework for Homie _, a lightweight MQTT convention for the IoT. Main target for Microhomie is the ESP8266 device and has been well tested and used on ESP32.

Read the Microhomie documentation _ to get started.

Learn from our examples until we have a "howto build nodes" section in the documentation or join the #microhomie channel on the MicroPython Slack community _ and chat with us.

2. Objective

MicroPython implementation of the Homie MQTT convention for IoT.

This project demonstrates how Python, MQTT, ESP8266 can be applied to a real-world Internet of Things (IoT) problem.

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?
