RF Bridge - HA without binary sensor

Configuration
1

Hello, I have an sonoff rfbridge and a remote RM433, It always worked fine, but I only noticed this week that it is not working.
After some search i think I found the problem but I dont know why its a problem:

In the configuration.yaml the code is the same.
This is the example for one of the remote buttons:

binary_sensor:
#Botão 1
  - platform: mqtt
    name: "comd1_1"
    state_topic: "tele/rfbridge/RESULT"
    value_template: '{{value_json.RfReceived.Data}}'
    payload_on: "DB9F78"
    payload_off: "DB9F78off"
    device_class: power
    qos: 1  
    off_delay: 0.3

but the binary_sensor doenst appear:

I havent made any change to it to stop working!
Can anyone have a clue of what is happening!

MQTT has it own Domain Know

mqtt:
  binary_sensor:
    - name: "comd1_1"
      state_topic: "tele/rfbridge/RESULT"
      value_template: '{{value_json.RfReceived.Data}}'
      payload_on: "DB9F78"
      payload_off: "DB9F78off"
      device_class: power
      qos: 1  
      off_delay: 0.3
