Hey everyone, I wanted to share my journey with implementing a circadian lighting system in my home. It’s been a fascinating project that combines technology, comfort, and a bit of personalization. Let me walk you through it!
I’ve always been intrigued by the idea of lighting that adapts to my natural rhythms. With the help of Home Assistant (HASS) and AppDaemon, I decided to take the plunge. The goal was to create a system that adjusts brightness and color temperature throughout the day, mimicking natural sunlight patterns. This not only enhances comfort but also supports better sleep and productivity.
Here’s how I approached it:
-
Research and Planning: I started by researching existing solutions and scripts. I stumbled upon an AppDaemon script that could generate circadian lighting values based on time, brightness, and color temperature. This was a perfect starting point!
-
Script Development: The script I found (available on GitHub) calculates “circadian brightness” and “circadian colour temperature” at specific intervals. I customized it to fit my needs, including an offset feature for those late-night work sessions. It uses
rgbxyfor color conversions, which made things much easier. -
Implementation: I integrated the script with my existing lighting setup. The script updates global variables (
c_brightnessandc_color) that are then used by another script to fade lights to the desired values every 4 minutes. This ensures a smooth transition between light states. -
Challenges and Solutions: One hiccup I encountered was the script not handling midnight transitions properly. After some tweaking, I managed to fix it, ensuring seamless day-to-night transitions.
-
Results: The results have been fantastic! My mornings are now greeted with warm, gradual light, making waking up much easier. During the day, the cool, bright light keeps me focused, and as evening approaches, the warmer tones help signal it’s time to wind down.
-
Tips for Others: If you’re considering a similar project, start small. Test the script with a single light or room before scaling up. Also, ensure your lights support the necessary color temperatures and brightness levels for optimal results.
This project has been a rewarding experience, blending technology with personal comfort. I’d love to hear about your lighting setups or any improvements you might suggest for my system!
