I finally took the time to install your add-on without docker. Works great so far! No more interrupted music hehe
Thanks
Community Hass.io Add-on: Google Assistant Webserver (broadcast messages without interrupting music)
Looks like remote casting has been fixed by google recently. Is it now possible to cast music with this add-on?

Any ideas what below could mean?

Bob, any idea how it can work? I just tried something with existing addon but it didn’t work. Something like: play some music
I think this is only for the Google Assistant Library and not the Google Assistant Service (previously known as the Google Assistant gRPC API) which is used by this add-on I believe.
The library exposes a high level API and the service a low level API but I’m not sure what’s the difference between those two.
I hope I’m wrong and may be we’ll see this feature soon !
Thanks for this addon and work 
unfortunately can’t make it work on my side. using hassio in a vm (coreos).
Looks like it needs access to sound device …

anyone here managed to start playing music using this ? Everything seems to work except turning on music 
Nope same here as well
Has anyone been able to broadcast to either a specific home device or a group of devices.
I’ve got multiple google homes but not all of them need to be getting some of the broadcasts.
Thanks
I’ve followed the steps to set this up on my hassio system. Previously I already set up the Google Assistant component to expose and control my lights and switches (which works great btw). So the basic process is clear to me.
Now with this plugin I can’t get my Google Home Mini to output anything. I can see my commands in the Plugin logs and they even show up under https://myactivity.google.com/ as “said broadcast {my message}” but the Google Home just continues playing music.
What am I doing wrong?
For those interested, I just started using the ‘do not disturb’ function for the rooms that shouldn’t get the broadcast and that works well.
Are your devices on the same network?
I have got 3 GH devices. As far as I understand broadcast doesnt work the way you wanted. broadcast will always send message on all GH devices currently linked under the same account.
Do you use the night mode with ‘do not disturb’ ? As you tried at 1:22 AM, it might explain it.
As Zpeed suggested, the dnd mode disables notifications such as broadcast.
yes. Hassio is running on a Raspberry Pi 3 connected via Ethernet while the Google Home Mini is on WiFi but it’s the same network.
That’s an interesting idea. Let me check when I get home from work (hopefully early enough 
)
what version of assistant SDK is being used currently ? Because apparently from 0.1.1 from feb this year you can cast music 
February 20th, 2018
The developer preview (0.1.1) of the Google Assistant Library for Python is now available. This version brings remote-casting support to the Google Assistant Library.
Google Assistant Library
FIXED Support for remote casting to Cast-enabled devices (for example, Ok Google, play Spotify on the Kitchen Speaker.
Indeed, Do Not Disturb seems to be the issue here. When I came home from work it worked like a charm but now (at 4 AM) it won’t make a sound. However I’ve checked my settings in the Google Home app and do not disturb is turned off for the device. Am I missing something? Clearly there should be more people affected by this if it just stops broadcasting messages at night.
Make sure the ‘do not disturb’ toggle is also turned off in ‘Night mode’ settings
Ugh hate the Google Home App and its settings in like 100 different places. That was it indeed, thank you! I feel like this could be useful for new users in a FAQ section of the first post.
