Yes it has been removed as a result of an exploit that requires some social engineering? Wish there was some more detail? Is it like clever or is like oh ya try typing rm -rf *dontypethisudiot . Anyways Frenck said we can use ssh…so is that better security wise and how do we do that?
I think it’s time to update the guide…

Hi Great guide and really good timing as I’ve just purchased a nest hub and find the cast integration to be flaky
because you are adding a install via PIP on a home assistant OS will it not remove itself when you update HA OS
I’m currently on 6.4 and can now see there is a 7.0
Yeah, I had to deal with the same issue. I found a way, it might be a bit
You can create a ssh keypair in the terminal with ssh-keygen -t rsa. Add the (content of the) public key in the configuration of the add-on.
Check if your key is working by loggin in with the key.
After that you can create a shell command or a command_line switch.
Here’s my example of the switch:
- platform: command_line
scan_interval: 60
switches:
castmorning:
friendly_name: "Cast ochtend"
command_on: "ssh -o StrictHostKeyChecking=no -i /config/ssh/id_ha_rsa **user**@192.168.178.XX catt -d 'your_device' cast_site http://ha-url/lovelace-cast/morning" #replace the /config/ssh/ link to the place where you host the key.
command_off: "ssh -o StrictHostKeyChecking=no -i /config/ssh/id_ha_rsa **user**@192.168.178.XX catt -d 'device' stop"

Hi. I run Ha on Raspberry.
“pip install catt” returns

How can I install gcc?

Having the same problem since yesterday. Using Home Assistant Blue (ondroid n2+).
Help is needed… Catt installation fails.
I fixed this by changing the initial command to:
python3 -m pip install catt==0.12.2
There have been a few updates in the past week which for some reason create an error during installation. Using the command above, you’ll install the latest version that doesn’t create errors on setup.
Side note: I also partially restored the SSH addon through Supervisor to v9.1.1 because I won’t have time soon to edit my automations that use the stdin service. Maybe if only changing the init command doesn’t work, you should do that too. Let me know if it worked for you!

init_commands:
- apk add build-base
- apk add py3-wheel #optional
- python3 -m pip install catt
This fixed it for me
Thanks!! It works!!
work for me! thanks!

Does anyone have a guide to use ssh instead of stdin?
1 Like
This would be helpful. I haven’t updated the Terminal add-on b/c I rely on the addon.stdin for several automations.
This is probably unrelated but I wanted to share it to see if anyone else has seen it.
Yesterday I saw a Welcome to Home Assistant splash screen appear on one of my Google Home Hubs.
It was full screen and included the HA logo and blue background.
I was in a hurry heading out the door so didn’t get to touch the screen to see if there was any interaction.
Has anyone else seen this and if so what is it?
CATT via ssh works exactly as described by Lesley.
only one little typo 
ssh-keygen -t rsa
Config for SSH Terminal should look somehow like
init_commands:
- python3 -m pip install catt==0.12.2
packages: []
share_sessions: false
ssh:
allow_agent_forwarding: false
allow_remote_port_forwarding: false
allow_tcp_forwarding: false
authorized_keys:
- >-
ssh-rsa
AAAAB3NzaC1y..........****yourKey**********........
and same as using stdin
always use stop command before starting new cast in automation
Big Thanks to Lesley

Hi, i have got CATT auto installing now using your above code (Thank you), do you or anyone here know how i can automate the cast, since the latest version of SSH doesn’t support the old method ( Using CATT - #492 by thehijacker )
Has the CATT 30 second display on a V1 hub problem been resolved ?
Using terminal, I am able to CATT to my V1, but it disappears after 30 seconds. My V2 hub will display the CATT 10 minutes. Then I issue a STOP then I can re-CATT.
@Luitertje I am working on your SSH method of creating a switch. Testing in terminal but it is asking for a password. No passwords I have tried have worked. I think it wants the id_rsa.pub key. How can I copy/paste the key into Terminal ? I used CTRL-right click-paste the id_rsa.pub key but it still has permission denied.
SOLVED: My issue was that the username&password should have been the username that is set up in the SSH&Web add-on and NOT one of the HA usernames
Hi Braindrian,
the purpose of a ssh key means that you don’t have to use a password actually. You did create the key right? Where did you store it? Also did you put the content of the public key (id_rsa.pub) in the configuration of the ssh add-on? Furthermore make sure that the /config/ssh/id_rsa in the code is the right path to where your id_rsa lives.

Thanks for the reply.
You mentioned testing the key with a login. Could you explain how I would do that?
When we generate the key-pair does it get associated with a specific user account? I will test logging in with Putty and the key.
I stored the keys in a folder /config/ssh.
init_commands doesn’t work, what do I use now? I don’t see anything in the ssh addon documentation for init_commands, is it a modified addon?
