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.
I’ve actually been trying to implement something like this myself, but I’m trying to do it natively in HA. What I’ve done so far is make an automation for each appliance that calls a script (with variables passed through for messages and whatnot) which notified each member of the household in parallel, based on whether they’re home or not.
My eventual plan is to make each appliance automation flip an input_boolean that sends an initial notification which can be dismissed (either by sensor, NFC tag or notification action). Then every so often or based on a trigger (like door opening, toothbrush doing off, etc.) it triggers the notification script again.
