Q. Can a patient in the hospital during Selichot, zoom a minyan and repeat with them the Thirteen Midot usually said only with a Minyan present?
A. Usually, any Zoom contact does not contribute to mitzvos that require a minyan. On question 2845 regarding saying Tashlich during the Aseres Yemei Teshuva via zoom we wrote:
Horav Shlomo Miller’s Shlit’a opinion is that one should not. The reason is that reciting Tashlich next to a body of flowing water is similar to other mitzvos, where the presence of the article, place or situation that brings about a blessing or Tefila, has to be real.
After all one recites a brocho only on real lightning or thunder, kiddush levana only on actually seeing the moon and not a picture or reflection or listening to the Megila and answering Kedusha or Kaddish only when the voices are real and present.”
