       - enabled: true
         name: 'My Thermometer'

   where mac property is you'r BT Thermometer mac address. See mitemp_bt docs for instructions.
3. Update or create sensor templates (this step will be simplified in future)

   sensor:
      - platform: template
       sensors:
           my_temp:
               friendly_name: "Entrance Temperature"
               value_template: "{{ states.sensor.my_thermometer.attributes.temperature }}"
               unit_of_measurement: 'ºC'
           my_humid:
               friendly_name: "Entrance Humidity"
               value_template: "{{ states.sensor.my_thermometer.attributes.humidity }}"
               unit_of_measurement: '%'
