The watch can access an internet only once in 5 mins.
It takes 5 mins to load calendar events after you log-in.
Then events are updated hourly to save battery life.
Manual refresh: After hiding and re-appearing, the watch updates calendars within 5 mins.
In default settings, battery consumption is better than with original Garmin watch faces (according to our measurements).
If you experienced a battery drain: didn't you coincidentally turn any sensor on (like wrist heart-rate monitor)?
Strong dial flavor is not supported by calendars yet. It displays the events, but it is not beautiful.
It also won't fit multiple metrics at the same time.
When no calendar is set, the watch loads your primary calendar.
You can add more calendars by pasting calendar IDs from Google Calendar settings.
The list of calendars must be separated by a space or comma.
First calendar has the same color as the watch. Second has a different color. The third is grayish. Then it repeats.
The calendar might fail to load on some devices due to a Garmin bug.
If you encounter it, please vote up here for Garmin to fix it soonish rather than laterish.
The temperature shown is the current temperature at your location, together with a maximum or minimum temperature forecast for next 16 h.
The current temperature can get outdated when there is no connection.
Weather forecast is being updated hourly. If you use calendar as well, it updates 5 mins after the calendar.
The forecast might fail to load in next occasions:
Connection: Occasionally, Garmin Bluetooth connection to your phone might drop without a notice.
Check the watch is connected e. g. by changing a color of the watch in Garmin Mobile Connect.
Calendar: failing to load will prevent weather to load as well. If you have a calendar on, can you turn it off to check if it is not the culprit?
If your last activity ended in a different location than you are now, acquire a GPS signal by any activity outdoors to update your forecast to your location.
Only newer watches like fēnix 6, Venu, vívoactive 3 or Forerunner 245 update their position from phone.
Check if Garmin's weather widget forecast isn't wrong as well.
You can choose an accurate weather forecast Yr.no or Clear Outside. Yr.no is best in Europe. Try (more pessimistic) Clear Outside in other regions or if not satisfied.
