----------------- Disclaimers, please read:
- CGM App is not intended to serve as or to replace the real-time display of CGM data of the primary device or standard blood glucose home monitoring.  All therapeutic decisions, including those regarding calculating insulin or other drug dosages, should be based on blood glucose measurements obtained from a blood glucose meter and not on data from the CGM App.  
- The CGM app is not intended to analyze, interpret, or modify the CGM data received from the primary device.
- The CGM App is not intended to replace self-monitoring practices as advised by a physician.
--------------------------------------------------
(Note: the wording, "a blood glucose meter", is from Garmin directly - In my opinion I believe they meant to say "approved therapeutic device" instead, in case you are using a CGM approved for dosing.)

CGM watchface that uses ConnectIQ 2 background API to fetch CGM data from your personal Nightscout site, or a local web service from xDrip+, Spike, DiaBox, or OpenAPS rig.

FYI:
- Make sure the Connect IQ app on your phone is able to stay active and using data in the background - there are usually system settings on your phone that allow that, for both battery and mobile data.
- Be sure to have your watch setting for "Time Source" set to "Auto" (and not "Manual"), to ensure the watchface can sync up properly to the CGM data.
- If using mmol units with Nightscout, make sure your site's configuration variable DISPLAY_UNITS is set to mmol (and not mmol/L). Small memory devices will also need to set BG display mode to mmol in watchface settings.
- There are no tone or vibration alerts possible in Garmin watchfaces, watchface notifications are on the display only.
- Watchface will attempt each interval's load from the online URL first (if set), and if it can't be reached then offline URL.
- If using a Libre 3 or other CGM which gives readings every minute (vs every 5 minutes), change the app setting "Seconds past each 5 minutes of time to refresh BG data" to 0 (or up to 59) to get more consistent updates.
- Monitor status codes show which info is available and being monitored.
- Error status code and data is shown only when info is available and in error state, as noted.
