So I see in the documentation it says one of the use cases is “Play rain sounds on bedroom speaker” and later down it says it can’t control media.
Are these the same things? I am just trying to have an automation for bed times for my kids and this is the last hurdle.
If they are the same things and that is the limitation, does anyone know how I could play white noise like that?
So turns out if the command just has the room it works, but if I specify the device it fails. it does the for normal Google assistant too, which is odd to me. Oh well got it to work!
Do you happen to have the code you used for this? I am trying to play the white noise sleep sounds and it just says it isn’t supported yet.
I just tried the following at it seemed to work for me:
service: google_assistant_sdk.send_text_command
data:
media_player: media_player.hallway_speaker
command: play white noise on Hallway Speaker
I tested this in my office and it worked, then tried it at home and it did not. Renaming the speakers fixed the issue, I think it was an ’ in the name. Thanks!
This has now stopped working for me 
The command appears in Google Web Activity, but it says:
Sorry, I can’t find that device.
Please make sure that it’s turned on and connected to the internet.
I’ve tried so many different orders and things but I cannot get it working again. Anyone hit this issue?
same here, this is just awful, i’m shocked google did this.
