Home Assistant Area slot program

Help
1

Has anyone figured out a way to query areas and area ids from Home Assistant? I have a slot program based on the example tweaked to output (Friendly name):domain.id and would like similar behavior for areas.

After banging on this for a while, I finally found a simple-ish way forward. I had to add the asyncws library to the virtualenvironment in my Docker image:

FROM rhasspy/rhasspy
RUN ${APPDIR}/.venv/bin/python -m pip install asyncws

Here’s the script.


import asyncio
import json
import os

import asyncws


with open(os.environ["RHASSPY_PROFILE_DIR"] + "/profile.json", "r") as f:
    config = json.load(f)["home_assistant"]

token = config["access_token"]
url = config["url"].replace("http:", "ws:") + "/api/websocket"


@asyncio.coroutine
def work():
    websocket = yield from asyncws.connect(url)

    msg = yield from websocket.recv()
    assert json.loads(msg)["type"] == "auth_required"

    yield from websocket.send(
        json.dumps({"type": "auth", "access_token": token})
    )
    msg = yield from websocket.recv()
    assert json.loads(msg)["type"] == "auth_ok"

    yield from websocket.send(
        json.dumps({"id": 19, "type": "config/area_registry/list"})
    )
    msg = yield from websocket.recv()
    response = json.loads(msg)
    assert response["success"]

    for area in response["result"]:
        print(f"({area['name']}):{area['area_id']}")


asyncio.get_event_loop().run_until_complete(work())
asyncio.get_event_loop().close()

This is nice since Home Assistant now allows services to target areas as well as entities.

Hi, total noob here. Can you please specify how to do this? Even the example you linked is misterious for me.

Thank you in advance!

This is awesome! I am pretty sure I can use this to build a slot program for entities with entity aliases. I have been looking for a way to pull entity aliases from the API for weeks now. Looks like i can use this with a call to “config/entity_registry/list” to get the entity list with aliases. Super kool!

I have to ask, where did you find that you could call this “type” in the WS call? I have been reading through the HA documentation and can’t find anything about this.

I hope you don’t mind. I used your areas script and turned it into a shell script that can pull an entity list including entity aliases. The shell script works perfectly as slot_program in Rhasspy and allows you to define a list of names/aliases for all your devices in HA and control each device using any name.
