@adonno I’m a happy user of your tag reader solution and thanks a lot for your work and effort.
I have a problem that I could not resolve or, maybe, I didn’t understand how it works.
Prerequisites
a. Wemos D1 mini
b. PN RFID 532
c. Card & tag, 13.56 MHz
d. master branch pn532_i2c
Use case
I want to use my Huawei Mate 20 Pro as an NFC Tag
What I did
- Open Home Assistant Companion which is logged in at HA instance
- NFC Tag option from Settings
- Write Tag on White Card
- Returning results
- platform: event
event_type: tag_scanned
event_data:
device_id: 93d872ca49dfe4d7
tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
- Fire event button
- Check if ce1685b2-0bdf-4786-bea4-39caa49c4035 is displayed in Tags from configuration
- Make the following automation in automation.yaml
- alias: "Huawei NFC Access"
initial_state: True
mode: single
trigger:
- platform: event
event_type: tag_scanned
event_data:
device_id: 93d872ca49dfe4d7
tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
action:
- service: switch.toggle
entity_id: switch.shelly_1pm
- Reload automation
- Swipe Huawei Phone
Expected results
- The bulb must be switched on
Actual results
- The bulb is not light on and a new entry is created in Tags
- Huawei and White Card still have different identificators
More actions
- Go To events and listen tag_scanned
- Scan Huawei and White Card
–> “device_id”:bf45cac435a56ede5256ea83fed4f9c0is the same for both.
–> tag id is different than the id created with HA Companion
–> device_id is different than the id created with HA Companion
–
3. Go to automation and at device_id paste bf45cac435a56ede5256ea83fed4f9c0 value
New automation code excluded tag_id
- alias: "Huawei NFC Access Device ID"
initial_state: True
mode: single
trigger:
- platform: event
event_type: tag_scanned
event_data:
device_id: bf45cac435a56ede5256ea83fed4f9c0
# tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
action:
- service: switch.toggle
entity_id: switch.shelly_1pm
- Reload automation
- Swipe White Card --> the bulb is switching ON
- Swipe Huawei --> the bulb is switching ON
- Check Tags from HA
New Tag is created for Huawei - Swipe Huawei again
New Tag is created for Huawei
Expected results
Huawei and White card should be considered one entity
When I write a new card
device_id: 93d872ca49dfe4d7
tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
must be used in automation in order to make two entities to act as one
–
More Testing
- Go To HA companion and read White Card
–> results
- platform: event
event_type: tag_scanned
event_data:
device_id: 93d872ca49dfe4d7
tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
- Make the following automation
- alias: "Huawei NFC Access"
initial_state: True
mode: single
trigger:
- platform: event
event_type: tag_scanned
event_data:
device_id: 93d872ca49dfe4d7
tag_id: ce1685b2-0bdf-4786-bea4-39caa49c4035
action:
- service: switch.toggle
entity_id: switch.shelly_1pm
- Fire the event directly from the HA companion / Button Fire Event
–> The bulb is switching ON and OFF
–> Verify-in Tags ifce1685b2-0bdf-4786-bea4-39caa49c4035was used == yes - Swipe Huawei in order to obtain the same result
–> a new tag is created
–> the bulb remains switched off
In conclusion
if I used Fire Event button directly from HA companion the phone trigger the action and in TAGS is used the device id which was created, but if I put the same values in the automation I am not able to obtain the same behavior

Hi, is that working ?
Has anyone tried to read an NFC tag with the HA iOS Companion App on an iPhone 12 Pro? I can’t seem to get it to read or write any card or tag. My HA Tag Reader picks up all my cards and tags fine however.
What NFC tags are you trying to scan? Not all will work on a mobile especially the lower frequency cards and the keyring tags. NTAG are 13.56 MHz tags and pretty much all NFC enabled phones can read/write to them. If you stick to the NTAG type tags you should be ok.

It was the card and keyring tag that came with my HA Tag Reader…so I figured there wouldnt be an issue. I ended up ordering another set of cards off Amazon and they worked…strange!
actually, on the order page, it is stated that these cards are read-only. Apparently only under iOS read-only
Don’t ask me why unfortunately I get them like that
Still working on it, it requires changes to the esphome source code in c, and my free time is… minimal
Hi
Already some time ago, but I have the same problem
iPhone Shortcuts setup reads NFC perfectly.
Shortcuts automation itself afterwards also recognizes tag an triggers events.
The tag reader for Home Assistant also recognizes the tag
But HomeAssistant App can not read the tag.
iPhone SE 2020, ios 14.2, HomeAssistant App 2020.7
Any ideas ? Is this a bug ? Or an oversight from my part ?

Have you written to the TAG first with HA? It needs to format it from within the app first before it can read it.
Hi, sorry for the noob question. I am brand new to this.
I have setup my home assistant on my Raspberry PI.
I have added the jukebox YAML.
I have my tagreader (thanks adonno), connected to Home Assistant and it reads the tags I scan.
But now I am lost. How do I actually make the jukebox work? I guess I need to associate events to the tags I scan, but how does it actually make the jukebox start playing the spotify song or album on the device I want?
My question is has someone made a step by step guide for making this work?
Thanks for any help you can provide.
You will need to create a script which selects a playlists depending on which tag was scanned.
Something similar to this would work:
script:
internet_radio:
alias: Play Internet Radio
sequence:
- service: media_player.volume_set
data_template:
entity_id: >
{% if is_state("input_select.chromecast_radio", "Lounge") %} media_player.lounge_speakers
{% elif is_state("input_select.chromecast_radio", "Bedroom") %} media_player.bedroom
{% elif is_state("input_select.chromecast_radio", "Everywhere") %} media_player.everywhere
{% elif is_state("input_select.chromecast_radio", "Back yard") %} media_player.back_yard
{% endif %}
volume_level: '{{ states.input_number.volume_radio.state }}'
- service: media_player.play_media
data_template:
entity_id: >
{% if is_state("input_select.chromecast_radio", "Lounge") %} media_player.lounge_speakers
{% elif is_state("input_select.chromecast_radio", "Bedroom") %} media_player.bedroom
{% elif is_state("input_select.chromecast_radio", "Everywhere except office") %} media_player.all_except_office
{% elif is_state("input_select.chromecast_radio", "Back yard") %} media_player.back_yard
{% endif %}
media_content_id: >
{% if is_state("input_select.radio_station", "Hit 92-9") %} http://ic6ti.scahw.com.au/6ppm_128
{% elif is_state("input_select.radio_station", "Nova 93-7") %} http://streaming.novaentertainment.com.au/nova937
{% elif is_state("input_select.radio_station", "Mix 94-5") %} http://sc01.scahw.com.au/6mix_32
{% elif is_state("input_select.radio_station", "96FM") %} https://icy.ihrcast.arn.com.au/au_012_icy
{% endif %}
media_content_type: 'audio/mp4'
Swapping out the radio station URL’s for Spotify playlists and the input_select info for your tag read data.
I know it’s not a nice simple guide but hopefully it helps.

Hey guys,
I have sucessfully installed the adonno Tag reader and this is working with the lastest version of HA with tags and services like shutter und switches.
But i could not get it working with spotfiy links on my sonos s2 system.
Can anyone give me a sample configuration of the automation action:
This is my current setting which does not work.
service: media_player.media_play
data:
entity_id: media_player.kuche
media_content_id: 'https://open.spotify.com/track/5T490vvoFNU6psep0NPmxs?si=OD-_qchVSiGIf3wT3FUllw'
media_content_type: music
Do i need to install the spotify HA integration? (This was also installed in the mean time, but down not work)
Thank you in advance, hope i will get fixed my christmas present for my daughter.
Here is my automation:
alias: Tag Scanner
description: ''
trigger:
- platform: event
event_type: tag_scanned
condition:
- condition: template
value_template: '{{ trigger.event.data.tag_id in tags }}'
- condition: template
value_template: '{{ trigger.event.data.device_id in media_players }}'
action:
- variables:
media_player_entity_id: '{{ media_players[trigger.event.data.device_id] }}'
media_content_id: '{{ tags[trigger.event.data.tag_id].media_content_id }}'
media_content_type: '{{ tags[trigger.event.data.tag_id].media_content_type }}'
- service: media_player.play_media

media_content_id: 'spotify:playlist:37i9dQZF1DWV0gynK7G6pD'
media_content_type: music
A0-C1-64-32:
media_content_id: 'spotify:playlist:37i9dQZF1DWV0gynK7G6pD'
media_content_type: music
Now i got it working
I’m sure this is possible, but I don’t have the experience to figure it out.
How can I identify which device (phone) scanned the tag.
Thanks
Hi @ds1707
How did you get it working? I am trying to make it work on a media_player which is an audio ChromeCast.
Hi,
im new to HA. I just created a NFC-Tag and used the tag for a automation to put off all my lights. But when i scan the NFC-Tag with my iPhone, i need to open the HA App on my iPhone first so the automation will do its job. Does someone know if i can make it happen that the automation goes on directly when i scan it without going to the app first? Thanks in advance!
You can Copy my Template above into a new automation yaml Mode. Does your Tag reader already Work?
Hi! It works well, I can scan a tag and it can trigger things. I tried adding the spotify integration. It works and starts a song in my Spotify account (the spotify media_player). But how to make it start on a specific Chromecast media_player? When I change the media_player in the yaml, and trigger the automation, I can hear the starting sound of the chromecast but the music never starts
