Hey everyone! I wanted to share my recent DIY project that I think might be useful for others in the community. After experiencing an issue with my wife’s fish tank pump running dry, I decided to create a Zigbee water level sensor using an Aqara door/window sensor and a water float switch. It was a fun challenge, and I thought I’d walk through the process in case anyone else is interested in a similar setup.First, I sourced the necessary parts: an Aqara sensor, a water float switch, and some basic tools. The process involved disassembling the Aqara sensor, soldering the wires from the float switch to the reed switch, and making a small notch in the case to allow the wires to pass through. I also added a piece of tape to secure the sensor’s interior piece back in place. The final assembly was paired with Deconz and integrated into Home Assistant, allowing me to monitor the water level and set up an automation to notify me when it gets too low.This project was a great way to repurpose an old sensor and add some peace of mind to our home. If anyone has questions or suggestions for improvements, I’d love to hear them! Also, if you’ve tried similar DIY projects, please share your experiences—I’m always looking for new ideas and tips.On a related note, I’ve also been exploring ways to integrate more smart devices around the house. For instance, I recently set up a smart outlet for the pump, which I plan to control through Home Assistant once the water level automation is fully tested. It’s been a rewarding journey, and I’m excited to see how I can expand this further.If anyone has tips on troubleshooting Zigbee sensor connections or suggestions for other DIY projects, feel free to drop them here. Happy tinkering!
