Small, high-temperature humidity sensors (hygrometers) inside the cavity detect steam buildup.
For items like roast chicken or artisanal bread, the oven would automatically open a small electronic vent to exhaust excess moisture at the final 10–15% of the cook time.
This ensures a "crackling" skin or crust without the user having to manually open the door or guess when the moisture levels are right. Why this fits the 9444X The Blomberg BEO 9444 X
While this model is known for its versatility, adding a sensor-based humidity control system would bridge the gap between traditional convection and modern steam-injection ovens.
