Inputs, Processing, and Output
Input: The workflow starts with a scheduled trigger every day at 9 AM.
Process: The OpenWeatherMap node fetches the real-time temperature for Berlin using the API key.
The temperature data passes to the Line node, which formats a message like “Hey! The temperature outside is XX°C.” using an expression.
Output: A personalized LINE message with the current temperature arrives in your chat.
Edge Cases or Failures
If the OpenWeatherMap node gives no data or errors, check if your API key is valid and the city name is spelled correctly.
If LINE messages do not send, verify if the LINE OAuth2 token is still valid and has proper permissions.
Always test the workflow manually after changes to avoid silent failures.
Customization Ideas
- Change the city in the OpenWeatherMap node to any other by editing the cityName field.
- Modify the Line node message template to add weather conditions or greetings.
- Change the notification time by adjusting the hour in the Cron node.
Deployment Notes
Keep your n8n instance running to send notifications daily.
If hosting n8n on your own server, consider self-host n8n for reliable uptime.
