Hi everyone, I wanted to share my recent DIY project—a custom smart sprinkler controller. This was a fun challenge that combined hardware and software to create a practical solution for my garden. Let me walk you through the process and share some tips that might help if you’re considering a similar project.First, I started by gathering the necessary components. I used a Raspberry Pi as the brain of the system, paired with a Waveshare DINMount 8CH relay board to control the sprinkler zones. For the enclosure, I opted for a sleek, weather-resistant box that I found on Amazon. The software side was powered by SprinklerD, a fantastic open-source package that integrates seamlessly with HomeKit and MQTT.Setting up the hardware was straightforward, but the real learning curve came with configuring SprinklerD. I had to dive into the documentation to understand how to set up the schedule and API endpoints. The system now runs autonomously, managing the watering schedule and even delaying runs if it rains, which is a huge convenience.One thing I struggled with initially was getting the API endpoints to work correctly for starting and stopping individual zones. After some trial and error, I realized the importance of precise timing and proper relay configuration. I also had to ensure that the Raspberry Pi was securely mounted to prevent any vibrations from disrupting the system.Looking ahead, I plan to enhance the system by adding a dashboard tile to monitor the software and the last zone that ran. This will give me a quick overview of the system’s status without having to log into the backend.I’d love to hear if anyone else has tackled a similar project or has suggestions for improvements. It’s been incredibly satisfying to see this project come together and make my gardening routine much easier. Thanks for reading, and happy DIY-ing!
