I think this is an important feature for religiously observant Jews. There’s a loophole where you’re not allowed to use appliances or something, but if the appliance just happens to operate itself on a prearranged schedule then apparently that’s okay. In the manual it may be called Shabbat or Sabbath mode. Without a battery backup it adds next to no per-unit hardware cost if the device already has a cooking timer or automatic safety shutoff feature so it’s probably standard on most ovens and microwaves in markets that have Jewish customers. You may also notice this behavior with elevators that automatically travel on a schedule.





Just be careful with SD cards if you’re using SBCs. Home Assistant does a lot of writing and if your SD card can’t handle repeated writes you may suddenly lose everything. Keep backups to another device and have a replacement SD card ready if extended downtime is going to be a problem for you.
