LightMyWatts – Transform Your Training Into an Immersive Light Experience! LightMyWatts isn’t just another training app – it’s a game-changer for indoor training. Imagine turning every pedal stroke or step into a visual masterpiece. With LightMyWatts, your effort doesn’t just show on a screen – it lights up your entire room. How does it work? Every watt you push and every heart beat instantly syncs with your Philips Hue lights, creating a dynamic color experience that mirrors your performance. Cruise in Zone 2 and enjoy a calming blue glow that keeps you steady. Ramp up to Zone 6, and watch your space ignite in fiery reds as you sprint toward your limits. It’s motivation you can see and feel. New Feature: Heart Rate Lighting Mode No spare BLE channel? No power meter available? Running on a treadmill? LightMyWatts now lets you use your heart rate strap to drive the light colors! Your heart rate zones become a vibrant visual guide – perfect for athletes who want the same immersive experience even without power data, or simply prefer training by HR. Whether you’re cycling, running, or doing a workout on the go, your pulse becomes your palette. Why LightMyWatts? Immersive Training: Your power or heart rate zones become a living light show. Personalized Experience: Configure your Hue bridge and group settings easily. Instant Feedback: No charts, no numbers – just pure visual energy. Whether you’re chasing watts, building endurance, or crushing intervals, LightMyWatts turns your training into an unforgettable sensory experience. It’s not just cycling – it’s performance art. Ready to ride in color? Download LightMyWatts today and make every watt – or heartbeat – shine! To use LightMyWatts alongside a training platform like Zwift, Rouvy, or MyWhoosh, your trainer (e.g., Wahoo) must support an extra Bluetooth channel. Alternatively, you can connect using a power meter or power pedals on your bike — or now, simply use your heart rate strap. You’ll also need a Philips Hue Bridge to set up the lighting connection. New: The app now supports Hue Pro Bridge! Simply select “Pro Bridge” on the settings page. We'd love your feedback! Let us know which trainer, power meter, or heart rate strap you’re using and how LightMyWatts works for you.
