Recently, I embarked on an exciting project to transform our newly built relax room into a haven of tranquility using smart lighting and Homey. The idea was to create a color therapy experience that dynamically changes hues to enhance relaxation, and I’m thrilled to share how it all came together.The room already featured a sauna, a comfortable bed, and calming artwork, but I wanted to add an extra layer of relaxation through color therapy. I decided to use RGB lamps from Ikea Tradfri and Philips Hue, which I already had set up in the room. The challenge was to synchronize their color changes smoothly and create a seamless experience.I began by designing a system that would continuously cycle through different colors. To achieve this, I utilized HomeyScripts and Better Logic apps. Here’s a breakdown of the setup:1. HomeyScripts: I created three scripts to control the RGB lamps: - relax_init_colour: Initializes all RGB lamps in the ‘Relax room’ zone to red. - relax_set_colour: Adjusts the hue of all lamps in the zone based on a parameter. - relax_set_white: Resets the lamps to white light, signaling the end of the therapy session.2. Better Logic Variables: I set up two variables: - in_therapy (boolean) to track whether the therapy session is active. - current_hue (number) to manage the current color hue being displayed.3. CountDown App: I configured a timer named TherapyCounter to control the interval between color changes.4. Flows: I created three flows to orchestrate the entire process: - Therapy Start: Initializes the session, sets the initial color, and starts the timer. - Therapy Stop: Ends the session and resets the lamps to white. - Therapy Delay: Manages the timing for color transitions.The result is a seamless color transition that occurs every 5 seconds, cycling through the full spectrum of hues. This creates a mesmerizing effect that complements the room’s ambiance perfectly. The system is easy to control, with just two flows needed to start and stop the therapy session.This project has been incredibly rewarding, not only for the technical challenge it presented but also for the positive impact it has on our relaxation time. It’s a testament to how smart home technology can enhance our daily lives in creative and meaningful ways.If you’re looking to add a touch of tranquility to your space, I highly recommend exploring similar projects. The satisfaction of seeing your ideas come to life is truly priceless!
