Location-Based Triggered Reminder via Telegram Bot (iOS)

This workflow integrates iOS Shortcuts with n8n to create a simple, automatic location-based reminder system. When the user arrives at a specified location, an automation in the Shortcuts app sends a webhook trigger to n8n. If the trigger matches predefined date and time conditions, n8n sends a Telegram message reminder to the user. This is perfect for repetitive weekly tasks like taking out the bins, customized with conditions for day and time. ## Key Features - Location-Based Trigger: Uses iOS Shortcuts automation to start the workflow upon arrival at a specific location. - Time and Day Validation: Logic in n8n checks the current weekday and time to ensure reminders are sent only when appropriate. - Telegram Integration: Sends reminders directly to your Telegram account using your bot. - Minimal Setup: Uses native iOS and simple webhook setup in n8n. ## How It Works 1. iOS Shortcut Trigger: When the user arrives at a designated location, the iOS shortcut sends a GET request to the n8n webhook. 2. n8n Webhook Node: Receives the request and triggers the workflow. 3. Conditional Check: An IF node checks if the current time is after 4:00 PM and it's a Wednesday (or any other configured condition). 4. Telegram Node: If the condition passes, n8n sends a message like "Don't forget to take the bins out." to your Telegram bot. ## Setup Instructions 1. Create a Telegram Bot: - Use **@BotFather** to create a bot and obtain your bot token. - Add Telegram API credentials in n8n with your bot token. 2. Setup iOS Shortcut: - Open the Shortcuts app on your iPhone. - Go to the **Automation** tab → Tap **+** → Create Personal Automation. - Choose Arrive → Select a location. - Add action: **Get Contents of URL**. Method: **GET**, URL: your n8n Webhook URL (e.g., https://n8n.yourdomain.com/webhook/your-path). - Save the automation. (You can also test the automation by pressing the Play button) 3. Import Workflow into n8n: - Load the provided workflow JSON. - Set your webhook path and Telegram credentials. - Adjust the logic in the IF node to your use case. In my case, I check if today is Wednesday and after 4 PM until Midnight. 4. Expose n8n Publicly: Ensure your n8n instance is publicly accessible via HTTPS so the shortcut can reach it. ## Customization Guidance - Change Reminder Message: Modify the text inside the Telegram node to suit different reminders. - Add More Conditions: Extend the logic to support more days, hours, or different trigger messages. - Add Multi-Channel Output: Send reminders via email, SMS, or Slack in addition to Telegram. - Use More Triggers: Expand to other types of shortcut triggers (e.g., NFC tag, leaving location, time of day). ## Security and Implementation - Webhook Protection: Avoid using easily guessable webhook URLs. - Secure Telegram Token: Store your bot token securely in n8n credentials, not in plain workflow text. - Limit Shortcut Scope: Only trigger the shortcut at trusted locations or with secure iCloud sync. - Automation Permissions: Ensure your iPhone allows shortcut automations to run without confirmation. ## Benefits - Automates repetitive location-based reminders without user interaction. - Provides a lightweight, native solution using iOS and n8n with no extra apps. - Keeps you on track for routine tasks like garbage days, medicine reminders, or arrival-based tasks. - Easily extendable for multiple locations or trigger conditions.
