Help to reboot remote router using automation

Configuration
#1

Hi

I want to reboot my Asuswrt router when the 2.4hz radio fails. I’ve got the Asuswrt integration working and its tracking devices using 2.4hz radio, so the automation is tracking a entity which is using that radio

I’ve also install the SSH keys so HA can SSH into the remote router without a password

I’ve created a few automation conditions but cannot get the action correct in the GUI or even the YML editor

Here is the automation.yaml file

- id: '1673906360178'
  alias: Reboot Router
  description: ''
  trigger:
  - platform: state
    entity_id:
    - device_tracker.garage_door
    from: home
    to: away
  condition: []
  action: []
  - service: /config/reboot.yaml

I then started to create a shell_command script here

reboot_router: ssh -l admin 192.168.0.1  "reboot"

Then the main reboot.yaml file

reboot_router:
  alias: Reboot Router Script
  sequence:
    - service: shell_command.reboot_router

But I’m struggling to put it all together to create an automation. Can someone help please ?

Thanks

Read shell command docs

Your automation should call the shell command service like below


- id: '1673906360178'
  alias: Reboot Router
  description: ''
  trigger:
  - platform: state
    entity_id:
    - device_tracker.garage_door
    from: home
    to: away
  condition: []
  action: []
  - service: shell_command.reboot_router

You should add shell command section in your config that defines “reboot_router” as the command you desire like

shell_command:
  reboot_router: ssh -l admin 192.168.0.1  "reboot"

Not certain above is 100% so verify with docs

By the way, there is another implementation of an ASUS router integration, by @Vaskivskyi, which already have a restart button and solve this for you. :wink:

Ok I’ve changed

The automation.yml file

- id: '1673906360178'
  alias: Reboot Router
  description: ''
  trigger:
  - platform: state
    entity_id:
    - device_tracker_garage_door
    from: home
    to: away
  condition: []
  action:
  - service: shell_command.reboot_router

Then the config.yml file

shell_command:
  reboot_router: ssh -i /root/.ssh/id_rsa -o 'StrictHostKeyChecking=no' [email protected] 'reboot'

I now get this error message in the logs

Error running command: ssh -i /root/.ssh/id_rsa -o 'StrictHostKeyChecking=no' [email protected] 'reboot', return code: 255

Have you ssh between these to server before?
Server is not in known host file so blocking connection

If you manually connect it may ask you “do you want to add” but if not you may need to manually add.

Docker container and host are not same device from ssh perspective so even if ssh from host you still need to do from container

I setup a SSH cert and it works from cli without password

Could the problem the client side of the SSH request is from a container not the host itself ?

Just checked the CLI

Do you seriously want such an automation ?, … reboot your router every time the
device_tracker.garage_door in ha, turns to " away" ?
