A clip-on timer that senses the exact moment your water truly boils — and only then starts the countdown. Perfect eggs benedict, soft or hard, every single time. And the best part: you build it yourself, from about EUR 25 of common parts.
"Three minutes for a soft-boiled egg" does not mean three minutes from when you pressed the button. It means three minutes of boiling. So you stand at the stove watching for bubbles, guess the moment, and accept that breakfast is a coin flip.
PotWatch takes that judgement away from you. It hangs on the rim of the pot with a stainless steel probe in the water, waits for a genuine, confirmed boil, and only then starts counting. When the food is ready it shouts until you answer.
You can walk away. That is the entire point.
Because timing starts from the real boil rather than a guess, the same preset gives the same egg every time. Not approximately — actually.
Set it and leave the kitchen. PotWatch handles the waiting, the counting and the shouting, and keeps calling until you come back.
A built-in barometer adjusts the boiling point for your altitude and today's weather. A one-time calibration tunes it to your own stove.
If the water boils away, PotWatch stops and alarms instead of quietly cooking itself dry. A failed probe is reported, never faked.
A Li-ion cell and USB-C charging. No cable trailing across the hob, nothing to plug in before cooking.
Every file is free: models, wiring, firmware. Don't like three minutes for a soft egg? Change one number and reflash. No patents, ever.
// every countdown starts from the confirmed boil, not from the button press
