Dashboard Cast Errors

GSD · June 5, 2023, 6:49am

Hi,

Can anyone help me solve an issue i’m having with casting lovalace dashboards to a Google Nest Hub 2 gen display?

My setup:

RPi 3B+
Home Assistant OS 10.2
Core 2023.5.4

Script calling the dashboard cast service (on a Tradfri E1812 button push with Z2M)

alias: Alarm Dash Cast
sequence:
  - service: media_player.play_media
    target:
      entity_id: media_player.living_room_display
    data:
      media_content_id: dashboard-alarm/0
      media_content_type: lovelace
    metadata:
      title: Alarm Control Panel
      thumbnail: https://brands.home-assistant.io/_/lovelace/logo.png
      media_class: app
      children_media_class: null
      navigateIds:
        - {}
        - media_content_type: lovelace
          media_content_id: ""
        - media_content_type: lovelace
          media_content_id: dashboard-alarm
mode: single
icon: mdi:tablet-dashboard

This setup was working pretty well until a couple a days ago, most likely until before a HAOS update or perhaps before a Google Home update, I’m not so sure which one exactly, but I’m pretty sure that one of this updates messed things up.

I’ve done a factory reset to the display removed it from the Google Home app removed the Google cast integration from HA and re-added it, but no matter what i do i always get 2 errors and two warnings when i cast the dashboards. The funny thing is that most of the times the dashboard is being rendered to the display, even though is taking a lot of time, but sometimes i only get a white screen and sometimes it gets stuck in the HA Nabu Casa screen showing the connected status, but the dashboard is not being rendered.

These are the errors i get:

Me too
Did you find any solution for this problem?

No, nothing yet. I’ve also tried to reach the Google Nest Community. I suspect it might the latest cast firmware update causing the issue.

I’ll get back with a reply if I find something new.

Hi,
I found a solution.
If I choose the Nest entity instead of device in automation it seams to work.

Hi,

Thanks for the feedback. I’ll give it a try and let you know what happens.

Sunnytur · June 25, 2023, 3:26pm

Sorry, it seam the problem is still there.

GSD · July 5, 2023, 1:26pm

Problem solved, by itself somehow, I didn’t do anything and there were no recent updates to HA that could’ve solved the issue. Perhaps the display’s cast firmware was updated, although I’m not 100% sure about that. But the great news is that the errors and the warnings in the HA logs are gone and the dashboard cast is working great once again.
