The problem
A few days ago, the built-in button card stopped appearing on the cast dashboard (but everything else, including custom:button-cards, still works fine).
I’m casting my Home Assistant dashboard to multiple Google Nest Hub v2 devices.
The standard buttons appear in the mobile app or when viewing from a web browser, just not when using the cast integration to cast the dashboard to the Google Nest Hubs.
What it looks like in a browser
What it looks like on my Google Nest Hub
All the buttons that are working are custom:button-cards
What I’ve tried
1
I created a new dashboard with a couple of buttons and some other cards, and the buttons don’t show up on this much simpler dashboard when cast either (but the buttons show up in a browser).
2
I restored a full backup (using the backups restore feature) from before the buttons disappeared, but that made no difference.
3
I’m running Home Assistant on a VM, so I restored the last complete backup of the whole computer from 2 months ago, and strangely that made no difference either.
4
Since a 2-month-old backup of the VM didn’t fix it, I dug out an older Google Nest Hub v1 with older firmware (powered off for months) to see if buttons would work on it, and I don’t think it immediately updated when I turned it on. Either way, the buttons didn’t show up on it either.
What is going on?
I’m quite stumped about why this is happening (and there’s no error reporting when a cast object doesn’t show up (that I know of)).
This started weeks after installing 2023.3.6 and is still happening after the update to 2023.4.2 (the latest at the time of this post).
Does anyone have any ideas? Has anyone else run into this problem?
edit 1: Feels very similar to this cast problem
edit 2:
Is this what the Home Assistant Cast Demo screen is supposed to look like or is this missing buttons too?
