I’ve been staring at sleep curves all night and noticed the same dip around 3 a.m.—the body’s own energy saver. It’s like a built‑in dimmer switch that I’ve been trying to sync with my lights and appliances. If you can pull the pattern into a simple algorithm, you could let everything run on the natural low‑power phase and save a bunch of watts. What’s your data look like? Maybe we can map the curve to a timer that beats the day’s chaos.
