How to alert me when devices have not report state within 2 days?

Configuration
1

i found a Blueprint for reporting battery status, to remind me when to replace battery at 30%. sadly this works only for some devices. some of my zigbee just die without any warning.
my idea is to have an automation to alert me when a device not reporting within 2 days. how would i write an automation for around 30 devices, that usually report their states at least twice a day, to alert me when any one of them dont report within 2 days. the Telegram would list which devices too.
i thought there would be a Blueprint but could not find.
thanks

See my answer here:

…but if your devices are that unstable it might be worth trying to find out why.

it only stops when no battery life is life. but monitoring battery life % is not accurate for some device. so i think monitoring a device’s state change is much much more accurate

I use an automation to send me an alert when a device state becomes unavailable for over 5 minutes:

thank you for sharing your code!

any idea what this symbol is?

when i paste your code into Notepad++, i get nonsense

That’s just a simple emoji. :smiley: You can take that right out or put in a substitute one instead.

Maybe have a look at this. It‘s my solution to find unresponsive devices.
