Israel's Chief Rabbi Discusses Technological Halachic Challenges with Shabbat Watch Rabbis

Chief Rabbi of Israel, Rabbi Kalman Bar, met with a delegation of rabbis from the 'Mishmeret Shabbat' organization, led by its chairman Rabbi Eliyahu Bayfous. The meeting, also attended by Rabbi Shmuel Yosef Shtitzberg, Rabbi Eli Friedman, and Rabbi Raphael Frank, secretary of the Chief, focused on current halachic and practical issues. Rabbi Bar praised the organization's work in safeguarding Shabbat observance, stating, "This is holy work, and observing Shabbat will surely protect and benefit the people of Israel with many merits."

The rabbis presented technological advancements in the construction industry, highlighting how 'Mishmeret Shabbat' has increased demand for halachic oversight during the planning stages of new buildings. Many real estate companies have sought the organization's guidance on integrating halachic considerations into smart building systems, which now heavily rely on sensors and digital controls. These systems, found in modern residential towers, can inadvertently cause Shabbat violations for residents through everyday actions like opening faucets or using elevators, often without their knowledge.

Rabbi Shtitzberg described the numerous questions received from residents nationwide and the solutions developed by 'Mishmeret Shabbat' in collaboration with leading companies. The importance of incorporating halachic supervision from the initial design phase and contractual agreements with developers was emphasized, as retrofitting after occupancy is significantly more complex and resource-intensive.

Rabbi Bar then raised the issue of kosher food technology, specifically addressing the prohibition of non-Jewish cooking (bishul akum). He proposed exploring a technological solution that would allow a kosher supervisor to remotely operate cooking systems in large kitchens, such as those in hotels, institutions, and catering services, thereby ensuring compliance with kashrut laws.

Following the discussion, Rabbi Bar requested that the 'Mishmeret Shabbat' rabbis draft a memorandum for approval by the Chief. This document will address the need for halachic oversight of technological systems in high-rise buildings, synagogues, and mikvahs, including water meters, pumps, and various sensors. Rabbi Ariel Cohen, CEO of 'Mishmeret Shabbat', expressed gratitude for the encouragement and practical guidance received, stating the organization is working to raise awareness about early halachic supervision to ensure modern systems comply with Jewish law before they are implemented.
