DashCast component for Home Assistant

DashCast for Home Assistant

This Home Assistant service allows you to cast a website to a Google Chromecast.

PS. All thanks to @stestagg, developer of DashCast app for Google Chromecast.

Installation

Method 1. HACS custom repo:

HACS > Integrations > 3 dots (upper top corner) > Custom repositories > URL: AlexxIT/DashCast, Category: Integration > Add > wait > DashCast > Install

Method 2. Manually copy dash_cast folder from latest release to /config/custom_components folder.

Configuration

Method 1. GUI:

If the integration is not in the list, you need to clear the browser cache.

dashcast's Issues

Is this possible?

Using this integration with no issues on a Nest Hub Max in my kitchen. However, I have a second Nest Hub Max that I'm planning on putting in a guest bedroom, for people who will be caretaking me after a major surgery. I have the lovelace view to be cast ready to go - I know I can make that second Hub a trusted network, but is there any way to have it login as a specific user? I'd like to largely limit their access to HA via that device (though the view doesn't give them many navigation options).

Thanks for your thoughts/assistance.

Doesn’t work for cnn.com

DashCast no stream

Had it working yesterday no issues with WebRTC RTSP stream. Today all I get is DashCast screen with URL at bottom. Its working ok still on 1 Chromecast but not on my other 2 which are all on the same network. I've restarted everything but same issue.

Won’t work is Sonos integration is active

For some reason when I try and cast it displays an error:
Cast to Displays: Error Executing Script. Unexpected error for call_service at pos1:’SonosMediaPlayerEntity’ object has no attribute ‘_chromecast’

The automation is not referencing anything to do with Sonos and not sure its conflicting

Can’t get past login screen on Google Hub

I have a script which casts the dashboard. I have the following in configuration.yaml:

homeassistant:
  auth_providers:
      - type: homeassistant
      - type: trusted_networks
        trusted_networks:
          - Xxx.xxx.x.xxx  # my Google Nest Hub IP
        trusted_users:
          Xxx.xxx.x.xxx: 'User id between brackets' 
        allow_bypass_login: true

However I cannot get past the login screen. I do not see a ‘hidden button’ to continue. What am I missing?

Dashcast stopped working after updating to HA 2024.3

After updating to HA 2024.3, all my dashcast based automations fail with the following error:

  File "/config/custom_components/dash_cast/__init__.py", line 25, in play_media
    dash.load_url(url, force)
TypeError: DashCastController.load_url() takes 2 positional arguments but 3 were given

I guess it is caused by an additional parameter of load_url() which was recently added to pychromecast:
home-assistant-libs/pychromecast@540fd67

This seems to be part of home assistants effort to improve their APIs:
home-assistant-libs/pychromecast#779

This is the first step in refactoring the callback functions to accept a bool status and an optional response.

LICENSE

I think this repo is missing a LICENSE file

Cant use touchscreen

Im trying to cast a lovelace dashboard however when I do it I get to the login screen for HA on the google home screen but it wont let me push any buttons or hit ok or anything

Google cast stops after 30 seconds - Nest hub

Hi,

After the Nest Hub is updated to Fuchsia it stops if I cast home assistant after 30 seconds now instead of 10 minutes as before.

Would it be possible to Use disableIdleTimeout as mentioned in Google docs?

https://developers.google.com/cast/docs/reference/web_receiver/cast.framework.CastReceiverOptions

window.castReceiverManager.start({statusText: "Application is starting", disableIdleTimeout: true});

Dashcast namespace issue in HA 2023.4.5 / supervisor 10.0

Today I've updated to HA 2023.4.5 / supervisor 10.0.

My service calls to DashCast stopped working, with errors like the one below in the HA logging.
It complains: Namespace urn:x-cast:com.madmod.dashcast is not supported by current app.
This when executing a DashCast:DashCast service call which was working fine before (I was a really happy user :)

Is there anything I can do / test to help solving this?
