In the same way ‘Voice assistant integration’ was added to every entity recently, it would be awesome if you could choose to mark your important devices / entities as something which you would get a notification on if they are unavailable for a period of time.
Yes, I know there’s a bunch of blueprints around this and you can create your own state change notifications, but you always need to add your important devices / entities there separately instead of in the context of the entity, and there’s a lot of factors that could be handled centrally (do not notify before startup has finished, if an entity depends on an integration that does not load etc).
