Notification system (self.homeassistant)

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.

Sounds like some logic you can tease out with node-red. I don’t know of a native way to do it in HA.

Yeah node red + the notification services on HA would definitely be how I do this. In fact, I kinda do already.

Sorry to not tell that, the plan is indeed for doing this in node red. I only want an example to put me on the right track and thought maybe someone else had something similar.

Should be able to just do it with automations and include "choose" action. 2024.1 looks like it makes it easier building blocks.

This is the answer. I have a handful of notifications setup this way. My routing logic tends to be much simpler but that's what "choose" is for.

The only tricky one may be to hold the notifications until later. I probably wouldn't bother with that personally. Instead I use the do not disturb functionality on the phone.

Looks nice at first sight. I'll definitely check it out thoroughly. I think it's exactly what I need. Thanks.

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.
