Hello,

I’m trying to connect nfc tag reader (pn532) to disarm alarm state.

The connection of pn532 to wemos d1 mini

works fine - I can read tag, pass it to HA and via automation disarm alarm.

The issue comes when I try to use not these nfc tags

but try to use my mobile phone - the tag address varies from reading to reading (i.e. the first tome it’s 08-01-02-03-04 the other time it changes to 08-ab-04-2a-02 and so on)

I suppose such changes are due to Google Pay app. So the question is is there any way to ‘fix’ nfc adress at mobile or any other way around the changing nfc address?

Unfortunately I didn’t overcome it - I just use iButton key from intercom door.
