What you need
- A compatible Garmin watch: Forerunner, fēnix, epix, Enduro, Venu, vívoactive or Instinct. See the list.
- Ando with your sensor connected, and an active membership.
- The Garmin Connect and Connect IQ Store apps on your phone.
Step 1: install Ando Glucose
- Open the Connect IQ Store app.
On your phone, with your watch paired.
- Search for “Ando”.
Open Ando Glucose, a data field, and install it on your watch.
Step 2: add it to an activity screen
- Open your watch in Garmin Connect.
Then Activities & Apps.
- Choose an activity.
Run is a good start. You can repeat this for trail run, bike, gym or any other profile.
- Add Ando Glucose to a data screen.
Open Data Screens, pick a screen and a field, and choose Ando Glucose from the Connect IQ fields. On the watch, the field is labeled Glucose.
You can also add the field from the watch: start the activity profile, open its settings, then Data Screens, and pick Ando Glucose among the Connect IQ fields. Menus vary a little between models.
Step 3: link the field to Ando
- Generate a device token in Ando.
In the Ando app, go to Settings, CGM, Garmin watch and tap Generate device token, then Copy token. It is shown only once.
- Paste it into the field settings.
In the Connect IQ Store app, open your device, then Ando Glucose, then Settings. Paste the token into Ando device token and save.
- Choose your unit.
Turn on Show mmol/L on watch if you read glucose in mmol/L.
That’s the only link between the field and your Ando account. No Garmin login is involved, and you can generate a new token or revoke it at any time.
Step 4: start a workout
Start the activity timer. The field asks for your glucose straight away, then every five minutes while the timer runs, through the Garmin Connect app on your phone. Keep your phone with you and online; the Ando app doesn’t need to be open.
| On the watch | Meaning |
|---|---|
| A number, like 128 | Your latest glucose, in mg/dL or mmol/L |
| -- | No reading from the last 15 minutes, field not linked yet, or membership inactive |
The chart in Garmin Connect
While the timer runs, the field records your glucose into the activity file. After you save the activity, Garmin Connect shows a glucose chart next to your pace and heart rate, with the average, minimum and maximum for the session. Garmin Connect always charts mg/dL, even if your watch shows mmol/L.
In Ando, the same workout appears with its full glucose curve, from before the start to an hour after, if you’ve linked Garmin or Strava. See Ando and Garmin.
If the field shows --
- The timer hasn’t started. The field only fetches glucose while an activity is recording.
- The token is missing or mistyped. Generate a new one in Ando and paste it again.
- Your phone is out of reach or offline, or the Garmin Connect app can’t run in the background.
- Your latest reading is older than 15 minutes. Check that your sensor app is uploading; our article on CGM delay explains the path your readings take.
- Your membership isn’t active. Glucose on Garmin is included with membership.
Questions people ask
Why does the field show --?
The field shows -- when it has no recent reading: before the timer starts, when the latest reading is more than 15 minutes old, when the token is missing or wrong, or when your Ando membership is not active.
Do I need to link my Garmin account to use the field?
No. The field is linked to Ando by the device token, not by a Garmin login. Linking your Garmin account is separate: it imports your workouts and sleep into Ando.
Can I use the field for any activity?
Yes. Add it to the data screens of any activity profile on your watch: run, trail run, bike, gym, hike and so on.
What if I lose or share my token?
Generate a new one in Ando under Settings, CGM, Garmin watch. The token is only shown once, and you can revoke it at any time.
Why is there no glucose chart in Garmin Connect?
The chart appears for activities recorded with the field installed from the Connect IQ Store and running during the activity. Check that the field was on one of the activity’s data screens and that it showed a value at least once.
