Export template temperature sensors to Alexa

I have two exterior temperature sensors (front and back). I created a template sensor to report their average:

  - sensor:
      - name: "Outside"
        unit_of_measurement: 'ºF'
        device_class: temperature
        state: "{{ (((states('sensor.outside_back_temperature') | float) + (states('sensor.outside_front_temperature') | float)) / 2) | round(1) }}"

It shows just fine on my main dashboard, but it is not available as an entity exportable to Alexa (whereas the two physical sensors are).

I want to be able to ask Alexa “What is the outside temperature?” and have her report the average. Not have to ask for individual sensors.

Try this instead:

Thank you. That worked!

  - platform: min_max
    name: "Outside"
    type: 'mean'
    round_digits: 1
      - sensor.outside_front_temperature
      - sensor.outside_back_temperature

This is also going to be very useful to keep an eye on the various battery levels and report the minimum one on my TileBoard!
