Device-related queries ("what is the <attribute> of <device>?")

[tetele]

At the moment you can only name entities in queries you perform.

Does anybody think it's a good idea to allow queries for sensor entities based on the device they belong to? For example, let's say I have a smart plug named "Washing machine plug". It exposes entities such as:

• Washing machine plug power
• Washing machine plug energy consumption
• Washing machine plug device temperature

If I wanted to learn about those, I'd have to say "what is the Washing machine plug device temperature?" for instance.

But what if I could say "what's the temperature of the washing machine plug?" (hint: device_class: temperature) or "how much power does the washing machine plug draw?" (hint: device_class: power).

      - sentences:
          - "how much power (does {device_name} (draw|use)|is {device_name} (drawing|using))"
        response: one
        requires_context:
          domain: sensor
          device_class: power
        slots:
          domain: sensor
          device_class: power

Is that useful?
