hi, i have this: https://de.aliexpress.com/item/Hohe-qua ... d41bfd49-0

and a d1 mini pro esp-8266 ex https://eckstein-shop.de/WeMos-D1-mini- ... EX-Stecker

I use it with Level Converter: https://www.ebay.de/itm/Pegelwandler-4- ... 2409796871



-Connect esp with USB Power
- COnnect 3,3V to LV and 3,3gnd to GND ( External not ESP )
- Connect 5v to HV and 5vgnd to gnd ( External not ESP )
Wiegard green > to HV2
Wiegard white > to HV1

From other level connector
LV2 (green) to ESP D6
LV1 /white) to ESP D7 i also User D3 or D4

In devide i set and activate Wiegand 26

On Hardware i also cange D6 D7 .. to Input
I have add fingerprints in Device Relay is okay .. But i get no tags !!!


EDIT: Maybe a GND problem ? Must all ESP,Levelshifter,fingerpint the same GND ? all from 12v Power ?

The Wiegand protocoll only works for RFID to my knowledge, not for fingerprint and not for the PIN you are able to enter.
Ever tried a RFID card and check the output?
