Thanks for taking the time to explain this and write out the detail. It lead me to a solution for my setup with duckdns addon after a few hours of fiddling.
The main thing was to map a new domain to my local hassio ip (as I had most of the other steps already in place)
Nice… Working! Was stuggling with getting my commands working, but this does the job!
Catt seems to play well with the Browser_mod media player and the Google Assistant Webserver. For example, you can cast your lovelace frontend to your Google hub, then play a seperate audio with Browser mod. Then you can send audio notifications (broadcasts) to the hub and it won’t interupt the music playing. In fact you can set your hub to show the broadcast text on the screen.
Okay I have a problem, I installed Catt and after running the command I get an error:
Running HA on a pi.
Could some one told me what’s wrong?

Sorry to reply on an old post but does your google home make the alert noise every 10 minutes or is there a way to disable as could see that getting a bit annoying?
(see this link for install instructions)
yes, i was also getting the beep every 10 minutes, to solve it, i created this in the cast.sh file that I now use:
if ! catt -d "Living Room display" status | grep 'PLAYING'; then
catt -d "Living Room display" volume 0
catt -d "Living Room display" cast_site http://192.168.178.87:8123/lovelace-test/0
fi
It checks if anything is playing, then it wont cast. If nothing is playing, it turns the volume off and casts the screen. I just leave the volume off. Whenever I say “ok google” the volume goes back on anyway. you could turn the volume back on after the cast, but that also makes a sound.
The automation I use to cast the cast.sh file is:
- id: '1589529246400'
alias: CastToHub
description: ''
trigger:
- minutes: /10
platform: time_pattern
condition:
- after: '5:00'
before: '23:30'
condition: time
action:
- data:
addon: a0d7b954_ssh
input: bash /config/cast.sh
service: hassio.addon_stdin
Can you also give “the command” that you mention?
Yes sure. The command is:
catt -d “Google Cast” cast_site ‘https://name.duckdns.org:8123/lovelace-hub/begin-hub’
Tried alsof without the port number.
Perfect thanks so much!
I think you need to remove the single quotes around the the address.
Removed the single quotes but still not working. Had the same error.
I did see other people cast directly from their http address instead of external (https) in your case:
catt -d ‘Google Cast’ cast_site ‘http://ip:8123/lovelace-hub/begin-hub’
also using only single or double quotes for the entire string
Thanks Juan, also tested with the local IP address, but stil no luck :S
But when I check the github, there is also an issue what’s looks like the same errors: https://github.com/skorokithakis/catt/issues/273
why are you using -d? That is used to set defaults.
For using the default device Google Cast (Nest device)
Well think I found the problem was related with the issue on github.
I did an upgrade from catt and now it will cast to my Nest hub.
So the command was just fine but he couldn’t found any cast devices. 
Hi @john2014 I have the cast working. Now I was checking with your options for the script and automation.
I have changed the script and automation with my own cast name and cast site.
But when I run the automation and checking the SSH log I see an error:
This was the first time checking. It told the Nest hub was offline. It was in standby, so when I turned it on that message is gone.
But still get the from line 1, and I don’t know what is wrong.

I have 3 Nest Hub, how can i set this up for 3 hubs?
I have edit the cast.sh,
if ! catt -d 192.168.196.210 status | grep 'PLAYING'; then
catt -d 192.168.196.210 volume 0
catt -d 192.168.196.210 cast_site http://192.168.196.156:8123/
elif ! catt -d 192.168.196.144 status | grep 'PLAYING'; then
catt -d 192.168.196.144 volume 0
catt -d 192.168.196.144 cast_site http://192.168.196.156:8123/
elif ! catt -d 192.168.196.111 status | grep 'PLAYING'; then
catt -d 192.168.196.111 volume 0
catt -d 192.168.196.111 cast_site http://192.168.196.156:8123/
fi
but this will not work, i get an error:
20-07-01 15:30:00 ERROR (MainThread) [supervisor.utils] Can't execute write_stdin while a task is in progress
Is the cast.sh exactly the same? Best to also post the commands you did when posting an error. I cant tell what is on line 1 from your post.
