Integrating My Oral-B Toothbrush into My Smart Home Setup

Recently, I embarked on an exciting project to integrate my Oral-B toothbrush into my smart home ecosystem. It might sound a bit unconventional, but the idea of tracking my brushing habits and syncing them with my smart devices was too intriguing to pass up. Here’s how I made it happen and why I think it’s a fantastic addition to any smart home setup.

The Setup

I started by researching how to connect my toothbrush, which supports Bluetooth, to my Raspberry Pi. After some digging, I found a Python script that acts as a bridge between the toothbrush and my MQTT broker. The script, available on GitHub, was surprisingly easy to set up. I followed these steps:

  1. Install Required Libraries: I ran sudo pip install bluepy paho-mqtt to install the necessary Python packages.
  2. Find My Toothbrush’s MAC Address: Using sudo hcitool lescan, I located my toothbrush’s Bluetooth address.
  3. Configure the Script: I edited the script to include my toothbrush’s MAC address, MQTT broker details, and the desired topic for data transmission.
  4. Set Up a Systemd Service: To ensure the script runs at boot, I created a systemd service file. This way, my toothbrush data is always available without manual intervention.

Integration with OpenHAB

The next step was to bring this data into my OpenHAB system. I configured the MQTT binding to listen for updates from my toothbrush. Here’s a snippet of my toothbrush.things file:

plaintext
Thing mqtt:topic:toothbrush “toothbrush” (mqtt:broker:mqttbroker) @ “Mqtt” {
Channels:
Type switch : running “running” [ stateTopic = “toothbrush”, transformationPattern=“JSONPATH:$.running”, on=“true”, off=“false” ]
Type number : pressure “pressure” [ stateTopic = “toothbrush”, transformationPattern=“JSONPATH:$.pressure” ]
Type number : time “time” [ stateTopic = “toothbrush”, transformationPattern=“JSONPATH:$.time” ]
}

This setup allows me to monitor my brushing duration, pressure, and mode directly within OpenHAB. I even created a simple dashboard to visualize my habits over time.

The Results

The outcome has been nothing short of amazing. Not only can I track my brushing habits more effectively, but I’ve also noticed improvements in my technique thanks to the real-time feedback. It’s incredibly satisfying to see my progress reflected in my smart home system.

Tips for Others

If you’re considering a similar project, here are a few tips:

  • Ensure Bluetooth Compatibility: Verify that your toothbrush and Raspberry Pi support Bluetooth Low Energy (BLE).
  • Secure Your MQTT Broker: If you’re using authentication, don’t forget to add the necessary credentials to your script.
  • Test Thoroughly: Run the script manually before setting it up as a service to ensure everything works smoothly.

Final Thoughts

Integrating my Oral-B toothbrush into my smart home has been a fun and rewarding experience. It’s a great example of how smart home technology can enhance everyday routines. If you’re looking for a unique way to leverage your smart home setup, I highly recommend giving this project a try. Happy brushing! :slight_smile:
