Hello! Why I can 't select GPIO (input data (DHT-22)) in the Dummy device settings ? (PIC below)

A 'dummy'-device is a dummy (1-4 values). It has no GPIO input. You must use another device type for your sensor.

Maybe something linke 'Environment - DHT...'.

Thank you for the answer,but I do not have the appropriate items, maybe the firmware is not the same? (I used hard 4M SON OF 2020.03)
UPD1: I found a solution to the problem- changed the firmware to normal_ESP8266_4M1M
