• To enable it, you need first to activate the Telegram component;
• Then, edit your automations.yaml file:

- alias: "Ngrok Public URL"
  hide_entity: true
  initial_state: 'true'
  trigger:
    platform: state
    entity_id: ngrok.public_url
  action:
  - service: notify.telegram
    data:
      title: '*Server*'
      message: 'Current public url: {{ states.ngrok.public_url.state }}'      

Debug

To enable debug diagnostics, add this to your configuration.yaml:

logger:
  default: WARNING
  logs:
    ngrok: DEBUG
