Hi,
I have found out that there seem to be multiple MAC adresses for one Access Point and maybe someone here can clarify which one means what. I also need help on understanding the formats.

Example:
My AP shows 3 MAC addresses:

  1. the MAC address shown in my WLAN router, made up from 6 parts, e.g. AA:BB:CC:DD:EE:FF and separated by ":".
    This is invisible in the AP UI.
  2. the MAC address shown in the AP UI in the tag list, made up 8 parts, e.g. 0000AABBCCDDEEFF and not separated by any signs.
  3. the MAC address shown in a freshly booted tag "Found the following AP: AP MAC: ...", made up out of 8 parts, e.g. AA:BB:CC:DD:EE:FF:GG and separated by ":".
    I would have expected two MACs, one for WLAN to router and one for Zigbee to Tag, but I have no idea what to make of three.
    I actually was very surprised to notice that the last MAC differs from the one shown in the UI.

Second question:
If I want to use a Tag's "copy" feature (so that multiple tags show the same content), I am asked for a MAC address. I am unable to make this work. I expect I shall enter the source tags MAC.
Shall this be with or without ":"?
Shall this be with 6 or 8 parts (my tags all begin with "00:00:..."?
So what of the following should I enter (I tried all and none seem to work actually)?

  • AA:BB:CC:DD:EE:FF (of source tag to be copied) or
  • AABBCCDDEEFF or
  • 00:00:AA:BB:CC:DD:EE:FF (of source tag to be copied) or
  • 0000AABBCCDDEEFF

I couldnt find any documentation on this feature either.

@nlimper commented on GitHub (Aug 10, 2025):

The correct form for the 'display a copy' content is AABBCCDDEEFF or 0000AABBCCDDEEFF.
If you set this content to a tag, and new content for the source tag is generated, the same content is also queued to the target tag. Both tags have to be of the same type.
