Sonoff, ESPeasy, MQTT

Hi!

I’ve installed a Hassio on raspberry pi 2.
I have 3 sonoff’s configured to comunicate with hass by mqtt.
Everything works fine when is running at home assistant 0.49.1.
After installing a hassio i have a problem to configure sensors

The following components and platforms could not be set up:
mqtt
sensor.mqtt
Please check your config

This is my configuration file with sensors section:

mqtt:
sensor:

  • platform: mqtt
    state_topic: “salon/bme280/Temperature”
    name: “Temperatura Salon”
    friendly_name: Temperatura
    qos: 0
    unit_of_measurement: “°C”
  • platform: mqtt
    state_topic: “salon/bme280/Humidity”
    name: “Wilgotność Salon”
    qos: 0
    unit_of_measurement: “%”
  • platform: mqtt
    state_topic: “salon/bme280/Pressure”
    name: “Ciśnienie Salon”

Do you see any problem here?
Thanks for help!
