Tasmota RF-Bridge MQTT problems

I think this would be easy for an expert :slight_smile: as I am a knob to Hass.io

I have flashed my Sonoff RF-Bridge.
Have a few door sensors and remotes and in Tasmota Console everything looks fine. I can find the codes for every sensor / button-push.

but when trying to get Hassio to see them it another storry?
I have scrolled through a lot of posts and come to the conclusion that I must do something obvious wrong?

My configuration.yaml looks like this:

“# Binary Sensors”

  • platform: mqtt
    state_topic: “tele/rfbridge/RESULT”
    name: “Toilet1_Door”
    value_template: ‘{{value_json.RfReceived.Data}}’
    payload_on: “5B040A”
    payload_off: “5B040E”
    device_class: Door
    optimistic: false
    qos: 1
    retain: false

But I keep getting failure msg. like:
The following components and platforms could not be set up:

Please check your config."

When testing in MQTTLens and subscribing to: “tele/rfbridge/RESULT” I get following result:
“RfReceived”: {
“Sync”: 14070,
“Low”: 490,
“High”: 1370,
“Data”: “5B040E”,
“RfKey”: “None”
So my MQTT server and the RF-Bridge do see each-other and the messages are working, something is missing in my configuration.yaml, for sure.
Do the bridge itself have to be set up? I have tried a million different ways in the config but no success?
