Wake up on time using Google Maps traffic, Twilio SMS, and iOS Shortcuts

📖 Overview

This workflow automates your morning wake-up call by calculating the perfect time to leave based on real-time traffic. Instead of a static alarm, n8n continuously monitors road conditions via the Google Maps Distance Matrix API. When the "strike time" is reached, accounting for both live traffic and your morning preparation; the workflow triggers a physical alarm on your iPhone via a Twilio SMS and iOS Shortcuts.

🛠️ System components

1. The Brain (n8n)

Check interval: Monitors traffic every minute during your "ready window."

Logic: Uses a mathematical expression to determine if you need to wake up now to make your arrival goal.

Formula:

T{wake} = T{arrival} - (T{traffic} + T{prep})
