This kit goes beyond a simple timer: it learns your weekday and weekend usage patterns, then fires the relay three minutes early so hot water is ready exactly when you are. Designed and tested for India’s 230V AC kettles, it’s an intelligent companion that elevates a daily ritual into a frictionless smart-home experience.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You’ll Build\u003c\/h2\u003e\n\u003cp\u003eA standalone predictive kettle scheduler that mounts near your kettle, reads the time from a DS3231 RTC, and automatically switches a 5V relay to turn on your kettle 3 minutes before your usual tea time. An OLED display, navigated by three tactile buttons, lets you view and edit the learned schedule — no phone or cloud connection required.
