I am using Homey for a lot of things but also enjoy the reminder every so often in order to bring a piece of toys to school or to put extra clothing in a backpack for swimming.
The flow I use for these reminders look like this:
07:45 is the time where we have breakfast. If the day is a Friday and the daynumber is between 24 and 31 it sends a pushbullet message.
Of course… sometimes a month has a friday where is 24 and a week after that 31 so you get an invalid reminder.
I cant figure out how to get passed this flaw.
