I'd like to create a notify group to use in automations that changes dynamically for the current people in a zone. I don't want HA to be spamming the families' phones when they're not at home.
I'd like to use this for notifications when the washer, dryer, dishwasher finish, or if someone left the freezer door opened and the temperature raised by more than so many degrees, etc.
What is the best approach to accomplish this?
