Abstract

Senseo Wifi is an open-source Internet of Things (IoT) project. Wifi'ify the Senseo coffee maker. Circuit and firmware for an internal Senseo hack to monitor and control the daily coffee brew (via MQTT) ☕️📶. The coffee maker is with no doubt a central element of our lives. In the Smart Home where every device is connected and automated, the coffee making can not be left out. It is built using C++, MQTT. Key capabilities include: Inform about the current state (Standby, Brewing, ...) of the machine; Notify about an empty water tank; Notify about a filled up coffee cup. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

The coffee maker is with no doubt a central element of our lives. In the Smart Home where every device is connected and automated, the coffee making can not be left out. Let's bring the Philips Senseo (Basic or Classic) into your Wi-Fi and control it remotely from your smartphone, through automation, or by extension via Alexa!

2. Objective

Wifi'ify the Senseo coffee maker. Circuit and firmware for an internal Senseo hack to monitor and control the daily coffee brew (via MQTT) ☕️📶

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

3. Key Features / Modules

  • Inform about the current state (Standby, Brewing, ...) of the machine
  • Notify about an empty water tank
  • Notify about a filled up coffee cup
  • Remote control the machine via Wifi/MQTT commands
  • Go through a complete brewing cycle automatically (Turn on, brew, turn off)
  • Audio feedback via a built-in speaker
  • Detect a cup via an optical sensor
  • Collect usage statistics, e.g. stored in InfluxDB and visualized in Grafana

4. Technology Stack

C++MQTT

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C++ compiler (g++)
  • Target board (e.g. Arduino, ESP32) where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/ThomDietrich/SenseoWifi.git
cd SenseoWifi

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?
