Wiegand Unknown Bit

The problem

I installed a wiegand FSTech keypad and RFID pad but i received the error in screenshoot. Is there any errors in the configuration (it is the default from the esphome site)? I configured the pad as Wiegand 26 Output (someone can give me the conversion procedure so i can control it?)

That looks like you're getting random data. Did you connect the grounds?

Hi @ssieb

thank you for your quick reply,

i connected black and red wires to 12Vdc, green(d0) and white(d1) wires to pins D1 and D2 on my wemos D1 mini. Have i to connect other wires?

Thanks

[ssieb]

Yes, you have to connect the black wire (assuming that's the ground side) also to the ESP GND.

Connected ESP GND...... Now everything is working....

Thank you @ssieb
