How can I understand this example settings?

How can I understand this example config:

What will happen if I say “is the door locked”? Will both sentences be matched? How can HA know which door is “the door”?

Being able to specify “the door” assumes the device you’re speaking to has been put in a room, and there’s a door in the same room. Otherwise it will pick an entity matching the name, which would be fine if you only have one. The “requires_context” causes it to pick one sentence or another as documented further down on that page.

But they’re just examples - a door that is a binary sensor is probably only an open/close sensor and doesn’t really represent “locked”.

My understanding is that the intent is specifically for binary sensors with device class “lock” not door sensors… some integrations or custom devices do not expose a specific “lock” entity.

Being able to specify “the door” assumes the device you’re speaking to has been put in a room, and there’s a door in the same room.

I’m still new to HA. Do I need to use something like Bluetooth Beacon to achieve this?

Shouldn’t the sentence be something like:

is the {name} <state>

or maybe have “door” in slots:

slots:
  name: door

or I don’t know how can HA even extract “door” from the sentence.

The “requires_context” causes it to pick one sentence or another as documented further down on that page.

How can HA even know the context I’m in by just analyzing this one sentence?
