Daily Weather Reports with OpenWeatherMap and Telegram Bot

Get automated weather updates delivered directly to your Telegram chat at scheduled intervals. This workflow fetches current weather data from OpenWeatherMap and sends formatted weather reports via a Telegram bot. ## Use Cases - Daily morning weather briefings - Regular weather monitoring for outdoor activities - Automated weather alerts for specific locations - Personal weather assistant for travel planning ## Prerequisites Before setting up this workflow, ensure you have: - An OpenWeatherMap API account (free tier available) - A Telegram bot token - Your Telegram chat ID - An n8n instance (cloud or self-hosted) ## Setup Instructions ### Step 1: Create OpenWeatherMap Account 1. Go to [OpenWeatherMap](https://openweathermap.org/api) and sign up for a free account. 2. Navigate to the API keys section in your account. 3. Copy your API key (you'll need this for the workflow configuration). ### Step 2: Create Telegram Bot 1. Open Telegram and search for `@BotFather`. 2. Start a chat and use the `/newbot` command. 3. Follow the prompts to create your bot and get the bot token. 4. Save the bot token securely. ### Step 3: Get Your Telegram Chat ID 1. Start a conversation with your newly created bot. 2. Send any message to the bot. 3. Visit `https://api.telegram.org/bot<YourBotToken>/getUpdates` in your browser. 4. Look for your chat ID in the response (it will be a number like `123456789`). ### Step 4: Configure the Workflow 1. Import this workflow into your n8n instance. 2. Configure each node with your credentials: #### Schedule Trigger Node - Set your preferred schedule (default: daily at 8:00 AM). - Use cron expression format (e.g., `0 8 * * *` for 8 AM daily). #### Get Weather Node - Add your OpenWeatherMap credentials. - Update the `cityName` parameter to your desired location. - Format: `CityName,CountryCode` (e.g., `London,UK`). #### Send a text message Node - Add your Telegram bot credentials (bot token). - Replace `XXXXXXX` in the `chatId` field with your actual chat ID. ## Customization Options ### Location Settings In the Get Weather node, modify the `cityName` parameter to change the location. You can specify: - City name only: `Paris` - City with country: `Paris,FR` - City with state and country: `Miami,FL,US` ### Schedule Frequency In the Schedule Trigger node, adjust the cron expression: - Every 6 hours: `0 */6 * * *` - Twice daily (8 AM & 6 PM): `0 8,18 * * *` - Weekly on Mondays at 9 AM: `0 9 * * 1` ### Message Format In the Format Weather node, you can customize the message template by modifying the `message` variable in the function code. The current format includes: - Current temperature with feels like temperature - Min/max temperatures for the day - Weather description and precipitation - Wind speed and direction - Cloud coverage percentage - Sunrise and sunset times ### Language Support In the Get Weather node, change the `language` parameter to get weather descriptions in different languages: - English: `en` - Spanish: `es` - French: `fr` - German: `de` - Polish: `pl` ## Troubleshooting ### Common Issues **Weather data not updating:** - Verify your OpenWeatherMap API key is valid and active. - Check if you've exceeded your API rate limits. - Ensure the city name format is correct. **Messages not being sent:** - Confirm your Telegram bot token is correct. - Verify the chat ID is accurate (should be a number, not username). - Make sure you've started a conversation with your bot. **Workflow not triggering:** - Check if the workflow is activated (toggle switch should be ON). - Verify the cron expression syntax is correct. - Ensure your n8n instance is running continuously. ### Testing the Workflow 1. Use the Test workflow button to run manually. 2. Check each node's output for errors. 3. Verify the final message format in Telegram. ## Node Descriptions ### Schedule Trigger Automatically starts the workflow based on a cron schedule. Runs at specified intervals to fetch fresh weather data. ### Get Weather Connects to OpenWeatherMap API to retrieve current weather conditions for the specified location. ### Format Weather Processes the raw weather data and creates a user-friendly message with emojis and organized information. ### Send a text message Delivers the formatted weather report to your Telegram chat using the configured bot. ## Additional Features You can extend this workflow by: - Adding weather alerts for specific conditions (temperature thresholds, rain warnings). - Including weather forecasts for multiple days. - Sending reports to multiple chat recipients. - Adding location-based emoji selection. - Integrating with other notification channels (email, Slack, Discord). ## Security Notes - Keep your API keys and bot tokens secure. - Don't share your chat ID publicly. - Consider using n8n's credential system for storing sensitive information. - Regularly rotate your API keys for better security.
