I recently set up a smart lighting system in my home and encountered a challenge that I’d like to share and discuss with the community. I’m using Wemos D1 modules to control RGB LED strips, and while everything works smoothly through Home Assistant, I wanted to integrate physical buttons for manual control without wasting GPIO pins on relays.
Initially, I was a bit stuck at first, but after some research and experimentation, I found a solution that worked perfectly. By using a combination of digital inputs and logical control within the firmware, I was able to trigger specific scenes or adjustments without dedicating individual GPIOs to each button. This approach not only saved resources but also made the system more scalable for future expansions.
I’d love to hear how others have tackled similar challenges or if there are alternative approaches that might be even more efficient. Have any of you found innovative ways to optimize GPIO usage while maintaining functionality? I’m always eager to learn new techniques and improve my setups!
