Hey everyone! I’ve been diving into the world of smart home integration lately, and I thought it would be fun to share a project I recently completed. It’s about connecting my Oral-B toothbrush to my OpenHab system using MQTT. Sounds a bit quirky, but it’s been a great learning experience! So, here’s the deal: I wanted to track my brushing habits and maybe even create some fun automation rules based on my brushing data. The toothbrush itself supports Bluetooth, which was a great starting point. I decided to use a Raspberry Pi as the bridge between the toothbrush and my OpenHab setup. The process involved a few steps. First, I needed to set up the Raspberry Pi with Python and an MQTT broker. I found a handy script online that handles the Bluetooth communication and data processing. It wasn’t too bad, just some terminal commands and a bit of configuration. The toughest part was figuring out the right MAC address for my toothbrush, but once I got that sorted, everything fell into place. For those interested, here’s a quick rundown of what I did: - Raspberry Pi Setup: Installed Python 3 and Mosquitto MQTT broker. - Script Installation: Downloaded the necessary script and installed the required libraries. - Service Configuration: Created a systemd service to run the script at boot. - OpenHab Configuration: Set up the MQTT binding and created the necessary channels to receive data from the toothbrush. Now, my OpenHab system can monitor how long I brush, the pressure I use, and even which quadrant of my mouth I’m focusing on. It’s pretty cool to see all that data in my dashboard! I can already think of some fun automations. Maybe a notification if I’m brushing too hard or a congratulatory message after a thorough brushing session. The possibilities are endless! If anyone else has tried integrating unusual devices into their smart home setup, I’d love to hear about it. It’s amazing how creative you can get with these projects! Happy brushing and happy automating!
