Automate Daily Weather SMS with n8n and Vonage

What This Automation Does

This workflow sends daily SMS messages with Berlin’s temperature at 9 AM using n8n.
It solves the problem of checking weather manually every morning.
The result is fast, reliable weather info sent straight to the phone.

The input is a daily trigger by Cron node at 9 AM.
The workflow fetches temperature data from OpenWeatherMap node using the city name “berlin.

It then formats a text message with the temperature value.
Finally, the Vonage node sends this SMS to the chosen phone number.

This automatic process saves time and reduces the stress of manually checking for weather updates daily.

Who Should Use This Workflow

This workflow is best for people who want quick weather updates without opening apps or websites daily.
It suits those who prefer messages on their phone about the temperature in Berlin.

Users who want to avoid outfit mistakes by knowing the daily weather early also benefit.
Anyone with basic understanding of SMS and APIs can use it easily.
