OPENWEATHERMAP SETUP

This watch face uses OpenWeather's One Call API 3.0 ("One Call by Call" plan) for extended data (Temperature forecast, UV, Wind, Humidity, Air Quality, Clouds, Precipitation).

Important: OpenWeather requires a payment card when subscribing to this plan, BUT you will NOT be charged as long as you stay within the free tier of 1,000 calls/day — more than enough for this watch face at any update interval. To be 100% safe, set a daily call limit in your OpenWeather account so billing can never occur.

1. Create a free account at https://openweathermap.org
2. Subscribe to "One Call by Call" at https://openweathermap.org/price
3. Recommended: in Billing plans, set "Calls per day (no more than)" to 1,000.
4. Copy your key from "API Keys" (a new key may take a couple of hours to activate).
5. In the Garmin Connect IQ app, open the watch face settings.
6. Paste the key into "Your OpenWeatherMap API Key".
7. Set update interval (10, 15, 20, 30, 45, or 60 min).


GPS COORDINATES

Weather, Sun Events, and Sunrise/Sunset require GPS coordinates, obtained automatically from your phone via the Garmin Weather service. If unavailable, open any GPS activity on your watch, wait for GPS lock, then stop it. The watch face reuses the last known position.


COLORS

All colors customizable via hex codes. Customize: Background, Foreground, Hours, Minutes, Date, Icons, Graph, Seconds, Moon, Solar Intensity, and Field 3 colors. Tip: use black on AMOLED to save battery.


SECONDARY TIME ZONE

UTC -12 to +12 with optional +30 min shift for half-hour zones (e.g., India UTC+5:30).
