This binary sensor stopped working several months ago (judging by the developer tool) for some unknown reason. I tried to revive it by restarting HA’s docker container. It didn’t help. Then I removed the sensor from within UI and restarted the container again hoping it will be recreated upon reboot. It didn’t happen - how can I restore this binary sensor now (and preferably make it function)?
Can I create this binary_sensor manually somehow after I have deleted it?
Can I re-create any binary_sensor after it was deleted via UI?
Have you tried deleting and re-installing the Jewish calendar integration?
Did the logging tell you something about the integration or sensor?
