Does anyone know if there are examples like this. I want to get a notification system in HA. It needs to be able to send the right notification at the right time on the right device.

For example, when the dishwasher is done, it sends a spoken notification to the nest hub in the kitchen, that is if the TV is on. If the TV is not on, but the computer is, it needs to send that notification to the computer room. At night it needs to hold the notifications and send them to the phone of the person that is the first to wake up. When we are not at home, we all get the notification on our phone. Also, when the dishwasher is emptied and the other person ticks the notification f.e.), and there's still a notification on a phone, it needs to disappear.

This is only one example, there are more things that can have a notification (another one could be a home greeting message), but it needs to be a system.
