Cannot specify powerview-g3.local as the hub address during setup

[tailg8nj]

The problem

I have a PowerView G3 hub. When I go to add the integration, the config flow asks for the host. I cannot specify the local DNS name powerview-g3.local, only the IP.

I've traced the code path to the following config flow:

core/homeassistant/components/hunterdouglas_powerview/config_flow.py

Line 31 in bc76dc3

api = await async_connect_hub(hass, hub_address)

Subsequent util call:

core/homeassistant/components/hunterdouglas_powerview/util.py

Line 28 in bc76dc3

websession = async_get_clientsession(hass)

which gets the HTTP client and TCP connector from homeassistant:

core/homeassistant/helpers/aiohttp_client.py

Line 340 in bc76dc3

resolver=AsyncResolver(),

Running sudo docker exec -it homeassistant python with the following reproduces the error:

import asyncio
import logging

import aiohttp
from aiopvapi.helpers.aiorequest import AioRequest
from aiopvapi.hub import Hub


_LOGGER = logging.getLogger(__name__)

logging.basicConfig(level=logging.DEBUG)

async def on_request_exception(session, trace_config_ctx, params):
    _LOGGER.exception("Exception request")


trace_config = aiohttp.TraceConfig()
trace_config.on_request_exception.append(on_request_exception)

async def setup(host):
    async with aiohttp.ClientSession(trace_configs=[trace_config]) as client:
        pv_request = AioRequest(host, websession=client)
        hub = Hub(pv_request)
        await hub.query_firmware()


asyncio.run(setup("powerview-g3.local"))

aiohttp.client_exceptions.ClientConnectorDNSError: Cannot connect to host powerview-g3.local:80 ssl:default [Domain name not found]
DEBUG:aiopvapi.hub:Gen 3 connection failed Failed to communicate with PowerView Hub

I am not sure if this is related to aio-libs/aiohttp#10186

I cannot curl inside the container either via:

$ sudo docker exec homeassistant curl -vs http://powerview-g3.local/gateway/info
* Could not resolve host: powerview-g3.local
* shutting down connection #0

However, executing curl outside the docker container works

$ curl -si http://powerview-g3.local/gateway/info
HTTP/1.1 200 OK

Workarounds:

• leveraging a static IP
• leverageing zeroconf config flow similar to this comment (although my hub doesn't seem to show up in Discovered, while Google cast and others do)

But I think this is a bigger issue than just PowerView. I guess this comes down to should folks expect to be able to leverage local DNS names in their integration setup or should integrations lean on zeroconf or other mechanisms?
