After a long journey of trial and error, I’m thrilled to share the success of my DIY Smart Qi Charger project, now in Version 2.0! 
Project Background
My goal was to create a smart charging solution that integrates seamlessly with my home automation system. The idea was simple: when my phone docks on the Qi charger, it should trigger a series of actions, like turning off lights or adjusting the thermostat. However, finding a reliable software solution proved challenging. That’s when I decided to take matters into my own hands!
Version 2.0: A Collaborative Effort
This time, I enlisted the help of my Dad and husband, who kindly agreed to assist with the woodworking. We used a 4.5" hole saw cutter to create a sleek, custom base from a piece of 2x6 pine. The design was refined to ensure the Qi charger and contact sensor fit perfectly, with just enough space to allow for adjustments.
Key Components
- Qi Charger: I sourced a reliable Qi charging pad from Amazon. It didn’t come with a cable, so I used an existing USB-C cable and a fast-charging plug.
- Contact Sensor: A Z-Wave contact sensor was essential for detecting when the phone is placed on the charger.
- Button: A small square button was added for manual activation, ensuring flexibility in how the system operates.
Construction Highlights
- Precision Cutting: We carefully routed out spaces for the charger and sensor, ensuring they were flush with the base.
- Sanding and Finishing: After assembly, I sanded everything smooth and applied a stain and polyurethane finish for a polished look.
- Wiring and Assembly: Wires were neatly tucked into shallow grooves I carved with a Dremel tool. The button was secured with tape to avoid interfering with connections.
Results and Integration
Since installation three days ago, the system has been rock solid. The LED lights on the charger gently glow through the opening, adding a subtle ambiance. Best of all, it seamlessly integrates with my smart home ecosystem. Now, docking my phone at night triggers a series of pre-programmed rules, making my home truly interactive and effortless to manage.
Lessons Learned
- Plan Thoroughly: Take the time to measure and mark everything before cutting.
- Sanding is Key: A smooth finish not only looks better but also protects the internal components.
- Test Early and Often: Ensure each component works individually before final assembly.
Invitation to Discuss
I’d love to hear from others who’ve undertaken similar DIY projects or have ideas for improvements. What features would you add to a smart Qi charger? Let’s brainstorm together and inspire each other to think outside the box! 
Happy building!
