Home assistant notification when any device is unreachable/unavailable

So the topic is quite straightforward,
I’d like to create an automation (or any other means) that will notify me when any of the devices connected to my HA instance is unavailable for any reason.

I know I can do that manually going through each of them 1 by 1 but curious if there’s a blanket method especially because I got a lot of devices now…

Basically I want to monitor how ‘sturdy’ the setup is and also pre-empt issues when I’m away and the wife is home dealing with an unresponsive automation/or worse :slight_smile:

Thank you!

The Watchman custom integration is excellent for what you’re after - it’s made things like that so much simpler for me.
