SmartThings OAuth

1. Automate Community
2. Home

Create Oauth tokens for authentication in SmartThings automations. Since Dec 2024, Smartthings tokens expire after 24h, so we need to now use OAuth authentication and loop daily to refresh the access token.
Source: https://developer.smartthings.com/docs/getting-started/authorization-and-permissions

Setup:
1. Download CLI
2. Create Smartthings App. No redirect URI needed, default is fine.
3. Create smartthings_app.json file in folder "Automate/smartthings", with:
{
"scope": "x:scenes:*",
"client_id": ,
"client_secret": ,
"redirect_uri": "https://api.smartthings.com/installedapp"
}
