Hello aleksandarzivkovic,
Well, blueprints are premade(by other community members or you) automations, scripts, or now templates. So your question is lacking a bit of background knowledge.
I don’t follow what you are looking for, but it is likely an automation. checking that something didn’t happen is not the most fun task to take on. You didn’t want to hear it, but adding a zigbee routing device between a solid part of the network and the outside device id likely what you need to happen,
Anyway…
I’m sure that can be done. Also having someone or something writing it for you means the second it misbehaves, you will be struggling back to find someone to fix it for you.
The best way to learn is to just try. Run thru the docs on getting started with the automation editor. If you get stuck, come back with what you have done.
