hmmm ok…
I found a tag. file (with hidden extension I’m assuming), in the hidden directory /config/ .storage
It has all the info I find under developer states page.
- Go to Developer Tools > Events
- Enter
tag_scannedin the “Listen to events” field - Click “Start Listening”
- Scan a tag
- The event’s information will be displayed. See if it
datacontains more than justtag_idanddevice_id.
Beautiness! that does have a lot more info, never messed with event listening. It was last_fired for the timestamp. Let me ask you this, this way doesn’t give static info on one tag only last scanned.
I’m trying to turn this
‘{{state_attr(’‘automation.med1_med’’, ‘‘last_triggered’’).date().strftime(’%Y-%m-%d %H:%M:%S’)}}’
into an sensor, so I will fit into an entity glance.
Do you have an idea what type of entity structure to use.
thx
Post the event data that it reported when you scanned the tag (so we can see all of the fields that are provided).
event_type: tag_scanned
data:
tag_id: 88b98f79-c6d8-4bd7-bd1d-d74d4368ca75
device_id: 9a97ef8100213bbf
origin: LOCAL
time_fired: "2022-10-23T21:41:15.216407+00:00"
context:
id: 01GG3CNXAGG7HVC63M9QJNDFRH
parent_id: null
user_id: 65f6c158e6e44cdb8238c8942ebb718a
this is from states tab for my automation / input boolean combo
this is where I’m getting my state_attr string from for a constant date which should reset itself each day or week.
last_triggered: 2022-10-23T21:41:15.224067+00:00
mode: single
current: 0
friendly_name: NFC_med1_Med
In your previous post you said:
Maybe I misunderstood you but I thought you meant your reported event contained more information than the event example I had posted. However, it’s identical; data simply contains tag_id and device_id. So now I don’t know what you meant by “a lot more info”.
Oh sorry, you’re right just labeled different after comparing… I guess I meant vs states tab. my bad!
If you want to record the moment when a specific tag is scanned:
template:
- trigger:
- platform: tag
tag_id: 88b98f79-c6d8-4bd7-bd1d-d74d4368ca75
sensor:
- name: Tag ca75 Scanned
state: '{{ now() }}'

Oh that makes sense now… thanks so much for all your help
You’re awesome!
If you add the following option to the example I posted above:
device_class: timestamp
the UI will display the sensor’s value relative to the current time. For example, “15 minutes ago”. The sensor’s actual value remains a datetime but the UI will display it as a relative time.

That’s what I was trying to replicate from dev states…perfect thx

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
then the cogwheel at the end:
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
Yeah definitely will mark post 
Have one little issue I can’t resolve is getting time format
(month, day, year hour : min) only.
Nothing seems to work, I hate to keep bugging you over this. But sometimes that little stuff gets me. 
Hey thanks for all your help… I guess walking away helped!!! got to work
Again, thanks for all your hard work.
For some reason I don’t see the solved check box

Thank you much @123 Taras so apreci!!

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') }}

Retried that string and works this time… I guess it was my formatting before
thanks makes it simpler!
