Sensor doesn't read tag

[abdullahvenom21]

I build the tag and in home assistant it reacts to clean tag,cancel tag,write random tag but does not react to any card when tapped against the tag module i tried with the tags that came with and also with a credit card but it does not respond to any card and at same time my phone picks up the cards

Sorry for highjacking the post but I have exactly the same issue (but maybe a different cause). But lets run through the checklist together (it hasn't helped me (yet) but maybe you're an excellent rubber duck ;) ).

wires:

• SCL to pin D1 - check
• SDA to pin D2 - check
• buzzer to D7 - check
• Led to D8 -> missing for you but shouldn't matter

switches:
switch 1: ON - check
switch 2: OFF - check

Firmware on device: Go to homeassistant & check if the tagreader is there.

Power on behavior:

• buzzer should beep
• power LED on the reader
• LED will shortly blink

Tags:

• Does it work with something else? (e.g. phone?) - check

Check serial logs:

Connect to the device & check the logs on boot. In my case it says:

[14:23:17][C][pn532:431]: PN532:
[14:23:17][C][pn532:443]:   Update Interval: 1.0s
[14:23:17][C][pn532_i2c:125]:   Address: 0x24
[14:23:17][E][component:082]:   Component pn532 is marked FAILED

Which is a bummer since that (for me) is the reason it won't read/write. The solutions I can find is make sure the switches are correct (which i think they are) but maybe there are other possible causes for this.

Lemme know if this helps you or if you have some additions.

EDIT:

JOOOOO So i just re-checked all the soldering joints & apparently my D1 wasn't rock solid. re-soldered it and it's working fine. So my reccomendation would be: check your solder joints!

Thank you for the help and i have the led but as the system is not working yet so i figured i will add them when the system works.
Right now i am making virtal home assitant on my pc and ill try to get the versions recomended for the tag reader i hope it works
And this is my first ever esp home project ill try my best to be rubber duck.

Ah, well then lets start at the beginning: Did you get esphome installed on the tag reader?

[abdullahvenom21]

Yes! I guess so,
I copied the file in the tag reader article on github and pasted it while editing the tag reader file.
Then i flashed my D1-mini with the same file with no changes.
Then the D1-mini created its own hotspot and connected the device to my home internet from there.
Then i connected the device to my home assistant server via cable
It started showing on the esp home dashboard.
Then i got the api key from the esp home dashboard and found D1-mini's ip address from my roter.
Then i connected the D1-mini to my home assistant server via the esp hone integration.
Then it only dives me option to:

• cancel Tag
• write tag
• another option
  I don't really remember it also gave me a restart button on home assistant dashboard the buzzer works when ever i change the tag to canel tag or write tag but never works when i bring a tag near but it should work😓

Awesome!

So If you enter the IP of your device you should be able to see the logging somewhere. Check the log & restart the device. If you can copy all the logging it writes when booting here that should be a good help.
