Scanning an Android phone as a tag? #62

Closed poblabs closed 3 years ago

poblabs commented 3 years ago

When using my android phone as a tag, and scanning it on the scanner, Home Assistant recognizes it as a different tag each time it's scanned.

Any tips on how to "lock down" just one tag id to my phone?

So android will change the UID on every scan however there seems to be people and apps that mange to emulate a ndef tag

But also please read this post that advises to just use a sticker instead of your phone

Looks like it's possible as an app. Would be great to have this added to the companion app as an option. @balloob @adonno
