Hi everyone, I wanted to share my recent project integrating my Mitsubishi Outlander PHEV with Home Assistant using MQTT. It’s been a really satisfying experience, and I thought I’d walk through what I did in case anyone else is looking to do something similar.
First off, I developed a small utility that communicates directly with the car via its Remote Control WiFi interface. From there, it sends data to MQTT, which then integrates seamlessly into HA. The setup was surprisingly straightforward once I got the protocol right, and the results have been fantastic.
One of the best parts is the responsiveness. Commands like adjusting the climate or checking the battery level come through in about half a second, which is incredibly smooth. I’ve also included features like querying door and lock status, which adds an extra layer of convenience.
I’m really excited about the potential for this project. I’d love to see more contributions, especially from other model year cars, to expand the functionality even further. If anyone has insights into decoding additional features or verifying compatibility, I’d be thrilled to collaborate!
For those interested, I’ve included detailed setup instructions and a bunch of info on the proprietary car protocol in the GitHub repo. It’s all there to help others get started without the hassle of reverse-engineering everything from scratch.
I can’t express enough how happy I am with how this turned out. It’s been a great way to stay connected with my car and integrate it into my smart home setup. If anyone has questions or wants to share their own experiences, I’m all ears!
Thanks for reading, and happy automating!
