PWM configuration in OpenHAB for ESP8266: MQTT State Topic and Command Topic issues

Hey, on the ESP8266 I made the simplest PWM, added to Things, Chanel and Item. But I think I've misconfigured something in the chanel because although I have a slider in the interface I can move it but the brightness of the diode connected to the GPIO doesn't change. I suspect I entered something wrong in:
MQTT State Topic I have stat/D1mini/RESULT entered. And in the MQTT Command Topic I have cmnd/D1mini/DIMMER. please suggest what is misspelled, what to change and what else if any.
