I’ve recently embarked on a project to automate the lighting in my downstairs toilet, and it’s been quite an adventure! The goal was to create a system that’s both energy-efficient and user-friendly, especially for late-night use. Here’s what I’ve learned along the way.
The setup involves a RGBW LED strip, which I wanted to use as the primary light source. To ensure reliability, I decided to use a physical switch (flashed with Tasmota) to control the power. This way, the lights would still work even if the OpenHAB (OH2) system went offline. But the real challenge was figuring out how to control the color without adding unnecessary delays or complexity.
After some research, I considered using a WiFi RGBW controller. While it seemed like a straightforward solution, I was concerned about potential delays in the lights responding, especially during power cycles. I also wanted the flexibility to adjust the color based on time of day or other conditions, which would require integration with OH2.
Another option I explored was creating a custom ESP32 solution. This would allow me to have precise control over the color channels, ensuring they were ready to go when the lights were powered on. However, this approach would require more hands-on programming and troubleshooting, which I was hesitant to dive into.
In the end, I decided to go with a combination of the physical switch and a WiFi controller, but I made sure to configure it in a way that minimizes delays. I also set up some basic rules in OH2 to handle color changes based on predefined schedules. For example, during the day, the lights stay at a neutral white, while at night, they switch to a softer, warmer tone to create a more relaxing environment.
One unexpected benefit of this setup is how well it integrates with my existing Google Home system. I can now control the lights using voice commands, which adds a whole new layer of convenience. It’s amazing how a little bit of automation can make such a big difference in daily life!
This project has taught me the importance of balancing simplicity with functionality. While it was tempting to go all-in on the latest smart tech, keeping things reliable and user-friendly was just as important. I’m really happy with how it turned out and look forward to exploring more automation projects in the future!
