[nfc tags] no deviceID

Configuration
1

hi,
i am trying to get NFC tags running and automate based only on certain devices which scan the NFC tag - i have running a test setup where i can cath the tag_scanned event BUT despite the HA documentation which says…

To find your scanner’s device ID, open Developer tools → Events → Listen to events and subscribe to tag_scanned . Then scan a tag on the reader and note down the device_id from the data section.

… i get an empty data[] like …

event_type: "tag_scanned "
data: {}
origin: LOCAL
time_fired: "2023-11-04T10:18:57.843205+00:00"
context:
  id: 01HECXFJD93RJ1JJXY03FS0W7R
  parent_id: 01HECXFJD8D865YPF0ZCMZRR7Y
  user_id: null

how can i get the deviceID ??

hmmmm…very weird … i tried again on the developer section → event listening page and now i get the device ID in the data section … strange but OK

now i am struggling with setting up proper automation to fire an action only when a certain deviceID read an NFC tag …

i assume this can be somehow done under the “conditions” section but i do not know how …
do i have to setup a template ?

You add it via YAML in the tag trigger.

  - platform: tag
    tag_id: xxxxxxxxx
    device_id: yyyyyyyyy

hmmm,
did this already

alias: Tag t3test is scanned
description: ""
trigger:
  - platform: tag
    tag_id: 33a3056e-cc72-41a4-87e0-baab8572e089
    device_id: caf7d04012ffd49a1d299ec09c93e83e
condition: []
action:
  - type: turn_on
    device_id: 4bca0bfadc51b5fc4f03371863afc4f1
    entity_id: 17daba063df14a7f787f3d8879415cfb
    domain: light
mode: single

and tested with a different device … and it still triggered :thinking:

Looks like a bug, the device_id is not taken into account…
