Hi all,
Is it posible to limit nfc tag’s for example i want to use it at my front door to disabled to alarm.
But it must only disable when i scan the tag, when a random person scan’s it nothing must happen, or maybe only a log event must be created.
Yes. You can limit your automation trigger to specific devices. See
The tag will be useless for anyone else.
Unless everyone else has HA app installed and your credentials.
The tag doesn’t have any information about your HA, it’s just a fingerprint.
Just like if you take a product Ina store and scan the barcode.
It doesn’t give you the price.
And the same product in two different stores has the same barcode but has a different price when you purchase it.
