Anyone here tried this kind on wiegand reader? im triying to connect it to esphome but it does not respond to LOGS when im pressing the keys… my config is D0 to GPIO4 and D1 to GPIO5 also GND to GND on both nodemcu and wiegand reader… hope someone here can help me…
I don’t see any wiegand branding on there. Are you sure?
I don’t see your yaml or your logs.
As you can see on the first picture there is a D0 and D1 pinout the pins use for wiegand… ill post my logs later when i get home.
I have reminded myself about wiegand and the fact that it is a protocol rather than a brand.
Don’t forget this note, dunno how you tell what mode it is in.
Some keypads are preconfigured by the factory to act as Wiegand input devices. In order to work with this component, they may need to be reconfigured to act as Wiegand 26 output or Wiegand 34 output devices.
Also my reading is that there are many variations on the protocol 
What do the instructions say about Wiegand26 output? Mine had to be manually put in that mode, it wasnt the default. The instructions should tell you…
Which esp board are you using?
Hopefully this is a good thread to post in.
I needed the (decoded) facility code and card code not the Hex tag or decimal value.
Using ChatGPT, I created the following code.
It works really well for my purposes
Strangely, I can’t figure out or get ChatGPT to simplify the code by using bitwise operations.
Hopefully this helps.
