OU Kosher, in collaboration with GE Appliances (GEA) and ZMAN Technologies, has introduced a device called the Shabbos Keeper for Ovens, which enables Shabbos and yom tov observance with certain GEA oven models.

Rabbi Tzvi Ortner, known as a solution-finder at OU Kosher, leads the effort to make modern smart kitchens Shabbat and yomtov-friendly.
