Start by making a virtual switch, call it "Shabbat Mode" if you want.
For the Friday - Saturday part, use Rule Manager and make two rules, one to turn the switch ON at the proper time (you can use Sunset +/- an offset). Second rule to turn the switch back off. You could potentially combine it into one rule but making two separate rules is a little easier if you have not used Rule Machine much.
I use this app: [RELEASE] Google Calendar, Task, Reminder, and Gmail Search and Gmail Notification Device to trigger a No School switch for when kids don't have school. Assuming you have a Google Mail / Calendar account, you could use this app and then manually populate the extra days/times you want the Shabbat Mode activated in a google calendar, and have that app trigger the same switch.
There are other apps with calendar functions as well, that's just the one I am using.
Once you have the Switch in place, you can use that switch to do multiple things across all the other rule and automation apps.
- Trigger rules to start running (ex timers of lights)
- Restrict rules from running (ex appliances or lights that are not allowed during this time)
