I recently embarked on a fun and budget-friendly DIY project to create a smart garage door system using a Shelly 1. After some research and a bit of tinkering, I managed to integrate everything seamlessly with Home Assistant, and I couldn’t be happier with the results! 
The project involved connecting a dry contact switch to simulate button presses for the garage door opener. Additionally, I added a reed switch to detect when the door was fully closed. By using custom Arduino code, I ensured the system communicated perfectly with Home Assistant, providing real-time updates on the door’s status (open, closed, opening, or closing) and enabling full control through the app.One of the best parts was seeing the door status update in real-time on my phone. It’s incredibly satisfying to know that I can now monitor and control my garage door from anywhere, all for under €25! 
If you’re looking to add some smart functionality to your garage without breaking the bank, I highly recommend checking out the full details, Arduino code, and bill of materials in my blog post linked below. It’s a fantastic way to dip your toes into DIY smart home projects while keeping costs low.
