Espeasy sensors (Howto?)

I need to read sensors from ESPEasy (Co2)



I’ve set here MQTT (OpenHAB)
What the next steps on HA side? Built in MQTT is deprecated, i’ve installed mosquito mqtt, i’m on the right way?

Tried to set mqtt in config, but sensor is not appearing

   - platform: mqtt
     name: "Co2"
     state_topic: "home/Kitchen_Sensor/mhz19/PPM"

On ESPEasy side:


It connects, how i configure sensor?
