Hebcal - Jewish Calendar driver for Control4 (FREE)


Many Jewish people who strictly observe Shabbat refrain from what turning electricity on or off during this period. They may also refrain from making adjustments to the intensity of electrical appliances.

The Chowmain Hebcal driver for Control4 imports data from Hebcal.com. This driver helps by automating detection of Jewish holidays and your standard Shabbat (observed from a few minutes before sunset on Friday evening until the appearance of three stars in the sky on Saturday night). By firing these events it assists with notification of Candle lighting (18 minutes before sundown) and Havdalah (after the appearance of three stars in the sky) along with the automation of electronic devices during this period.
