With the HomePilot, you have the option to treat public vacations and your own holidays/vacations/days off as you would a Sunday.
If you have specified in the triggers for opening the shutters that they open at 9 o'clock on Sunday instead of at 7 o'clock, then the shutters will also open at 9 o'clock on one of the holidays mentioned. Nothing else needs to be changed in the triggers and scenes for this.
In the video at https://youtu.be/1bRB0lDMEBI we have described how to create custom triggers for the weekend.
Activate the holiday function under Settings - Device configuration - Holiday function.
After activating the function, select Country - Region - City if necessary.
Custom holidays can be optionally added by tapping the + and then setting your own "holiday" with name, start and end date.
