LG TV requires ares-novacom

[emise]

To install this on the LG TV, we need to install ares-novacom which is not in the open source version of ares cli. This is so we can connect to the TV via the --getkey command.

To make it work on LG TV, all the commands need to include --device <device_name> because the LG version of ares cli doesn't have a default setting. I've also discovered that you can only install on the profile with ip address+port 9922, not the default emulator profile with port 6622.

Just a suggestion to add some more documentation on these workarounds. Thanks a bunch for creating and sharing this!

Configuring @webosose/ares-cli with Developer Mode App

• Enable developer mode, enable keyserver
• Download TV's private key: http://TV_IP:9991/webos_rsa
• Configure the device using ares-setup-device (-a may need to be replaced with -m if device named webos is already configured)
  • PASSPHRASE is the 6-character passphrase printed on screen in developer mode app

    ares-setup-device -a webos -i "username=prisoner" -i "privatekey=/path/to/downloaded/webos_rsa" -i "passphrase=PASSPHRASE" -i "host=TV_IP" -i "port=9922"

Configuring @webosose/ares-cli with Homebrew Channel / root

• Enable sshd in Homebrew Channel app
• Generate ssh key on developer machine (ssh-keygen)
• Copy the public key (id_rsa.pub) to /home/root/.ssh/authorized_keys on TV
• Configure the device using ares-setup-device (-a may need to be replaced with -m if device named webos is already configured)

  ares-setup-device -a webos -i "username=root" -i "privatekey=/path/to/id_rsa" -i "passphrase=SSH_KEY_PASSPHRASE" -i "host=TV_IP" -i "port=22"

Note: @webosose/ares-cli doesn't need to be installed globally - you can use a package installed locally after npm install in this repo by just prefixing above commands with local path, like so: node_modules/.bin/ares-setup-device ...

Thank you! One thing for me - somehow the private key path was already configured to the default ~/.ssh path, so I moved the file there and referenced only the filename rather than the entire path.

this explanation has to be added into the installation guide. was very helpful!

btw this is outdated; the official CLI from LG is required in order to not run into permission issues while installing. See this https://forum.webostv.developer.lge.com/t/an-error-appears-when-im-trying-to-install-ipk-file/2345
