This guide only applies to phoenix V1 (V2 does use garmins own weather instead)

Do following to get an API key from openweathermap:

• get a free API key from openweathermap.org

• subscribe for a free account, then you’ll get an API key that you can use for yourself
• enter this API key inside my app’s setting inside the Weather - API Key field
• get a GPS signal (open an app like running, wait for the green GPS signal and go back to the watchface)
• wait for about 10mins and you will see the weather data
