How it works
Three things happen. You only do one.
Dough goes in, a temperature gets picked, and the box does the watching.
1
Place the dough. The lid reads its height.
A time-of-flight sensor in the lid measures lid-to-dough distance every 30 seconds. Height is 300 mm minus that distance.
2
Pick a temperature. The chamber holds it.
Set 20 to 32 °C in the app. The PTC heater and fan keep the chamber within half a degree, winter or summer.
3
The curve flattens. Your phone tells you.
The app draws the rise as it happens and, when the slope drops, sends one notification: your dough peaked, bake in the next 20 minutes.
