I'm trying to wire the mfrc522 and the huzzah but i can't seem to figure out the rst pin.
I found the pin out diagram but it doesn't show or idk how its labeled as.

use Wemos table from your link. here is the mapping to esp8266 io pins
RST/Reset D3 = io 0
SPI SS D8 = io 15
SPI MOSI D7 = io 13
SPI MISO D6 = io 12
SPI SCK D5 = io 14
If you want, you can use any pin for SS and reset. See the examples.
#define SS_PIN 4
#define RST_PIN 5
MFRC522 mfrc522(SS_PIN, RST_PIN);
Use GPIO0 (D3 on the Wemos). The reset signal is under program control in the library and isn't the same as the ESP8266 reset input.
