Automate Daily Berlin Weather Alerts with n8n and Pushover

What This Workflow Does

This workflow gets the daily weather for Berlin at 9 AM automatically. It helps users who waste time checking weather apps every day. Instead, it fetches temperature data from OpenWeatherMap and sends a push notification using Pushover.

The goal is to give a simple weather update message each morning without manual steps. This saves time and stops missing weather changes.

Tools and Services Used

• n8n: For creating and running the automation workflow.
• OpenWeatherMap API: Supplies current temperature data.
• Pushover: Sends push notifications to the user’s device.

Inputs, Processing, and Output

Inputs

• Scheduled time (9 AM) triggered by Cron node.
• City name set as “berlin” in the OpenWeatherMap node.
• API keys for OpenWeatherMap and User Key for Pushover.

Processing Steps

• Cron node triggers workflow at 9 AM daily.
• OpenWeatherMap node queries current temperature of Berlin using the API key.
• Pushover node uses OpenWeatherMap data to create a message and send a push notification with the temperature.

Output

A push notification arrives on the user’s device. The message says: “Hey! The temperature outside is [temperature]°C.”

Who Should Use This Workflow

• Anyone who wants daily weather info automatically every morning.
• Users busy with daily routines who want to save time checking weather apps.
• People wanting simple weather alerts without opening apps.

Beginner Step-by-Step: How to Use This Workflow in n8n

Step 1: Import the Workflow

1. While inside the n8n editor, find and use the Download button on this page to get the workflow file.
2. In n8n, click the top-right menu and select Import from File.
3. Choose the downloaded workflow file to upload it.

Step 2: Configure Credentials

1. Add your OpenWeatherMap API Key in the workflow credentials section as required.
2. Add your Pushover User Key in the credential setup for the Pushover node.

Step 3: Update Settings if Needed

1. If desired, change the city name inside the OpenWeatherMap node.
2. Adjust the trigger time in the Cron node if you want a different notification hour.

Step 4: Test the Workflow

1. Run each node manually to verify data fetch from OpenWeatherMap and message sending via Pushover.
2. Confirm the push notification arrives on your device with correct temperature data.

Step 5: Activate for Production

1. Toggle the workflow’s Active switch in n8n.
2. This sets it to run daily at the set time, sending weather updates without manual steps.

If the user prefers self-host n8n, the workflow can be imported and activated similarly on that setup.

Customization Ideas

• Change the city by editing the OpenWeatherMap node’s city name field.
• Modify notification time by adjusting the hour in Cron node settings.
• Add more weather info in the Pushover message using expressions like {{$node["OpenWeatherMap"].json["weather"][0]["description"]}} to show weather description.

Common Issues and Fixes

Issue: Pushover node shows “Invalid User Key” error

Cause: Wrong or missing Pushover User Key credential.

Fix: Check the credentials in n8n, re-enter the correct User Key, then try testing the notification again.

Issue: OpenWeatherMap node shows no data or empty temperature

Cause: Incorrect API Key or wrong city name.

Fix: Verify API Key accuracy and validity. Check city name spelling and if it matches API specifications.

Pre-Production Checklist

• Make sure nodes Cron, OpenWeatherMap, and Pushover are connected correctly.
• Test each node’s function individually before running full workflow.
• Confirm API keys and credentials are valid and active.
• Verify receiving push notifications on your device when manually testing.

Deployment Guide

After testing, activate the workflow to run automatically at the set time.

Monitor workflow runs and execution status inside n8n.

Update trigger times or city names any time through the nodes’ settings.
