Built a smart home setup that tracks my sleep and adjusts everything automatically. When my phone hits sleep mode, lights dim gradually over 30 minutes, thermostat drops 3 degrees, and white noise starts playing through my speakers.
Morning’s even cooler - it watches my sleep cycle through my fitness tracker and wakes me during light sleep within a 30-minute window. Lights come up slowly, coffee maker starts, morning playlist begins.
Took 3 months to get everything working right. Had to connect my phone, smart lights, thermostat, coffee maker, and fitness tracker through different APIs. Hardest part was making the sleep data trigger everything else consistently.
I actually wake up naturally now instead of getting jolted by an alarm. Sleep quality got way better once I stopped fighting my natural rhythms.
Daily use: automated grocery list that adds items when I scan empty containers with my phone camera. No more annoying store runs when I discover I’m out of milk or eggs.
