Yeah, I don’t remember the exacts, but the simple forward way didn’t work (reliably) for some reason back then.
I use a mix of external NFC readers (ESP-Home) and the build in the phone one, i always had so scan twice or three times before the template switch would update if i scanned from a different device then the last one.
anyway, good to hear the straight forward way now works.

You can name/rename tags under the config → tag tab

other than being more recognizable than the codes this doesn’t make it a usable entity…

For the last_scanned part see excellent suggestions in this thread.
You would have to create some template sensors

Nothing seems to work, I hate to keep bugging you over this. But sometimes that little stuff gets me. :rofl:

If you’re interested, you can replace this:

{{ as_timestamp(states('sensor.date_time_iso')) | timestamp_custom('%a %B %-d, %I:%M %p') }}

with this:

{{ now().strftime('%a %B %-d, %I:%M %p') }}
