 Alarms and Alerts

Many alerts can be setup with xDrip+.

It is recommended to enable at least three alerts if xDrip+ is your only glucose monitoring app:

  • Low alert
  • High Alert
  • Missed readings alert

Glucose Level Alerts List

Glucose Level Alerts List

By default, one low and one high alert are defined.

Low alerts will trigger when BG is equal or below the alert value, high alerts when BG is equal or above.

To create a new alert, touch the CREATE LOW or HIGH ALERT title bar.

To modify an existing alert, long touch the alert

  1. You can name an alert the name you want, as long as no other alert has the same name
  2. The threshold is the BG level that will trigger the alarm, only one alarm can use this value
  3. Default snooze is the delay that will be proposed when snoozing
  4. The alarm will trigger again every x minutes if not acknowledged

Alert volume profile

You can customize the volume of your alerts

Alert volume profile

 High ○    
 Medium ○    
 Ascending volume ●    
 Vibrate only ○    
 Silent ○    

Ascending volume is recommended if you don't want the alarm to blare immediately (useful during the night). You can also delay ascending volume to filter noisy readings and limit the maximum volume.

Audio Focus

Audio Focus allows you to decide how to handle other sounds when an xDrip+ alarm or alert triggers.

Audio Focus

Choose what to do with other apps while playing alerts and adjusting system volume levels

You can automatically lower the volume, pause the other apps playing sounds (like media players) or pause all other sounds in order to better focus on xDrip+ sound.

Smart snoozing
Smart alerting

Smart snoozing and alerting avoid the alert to trigger or re-raise if BG is going in the right direction (upwards for low alerts and downwards for highs). The threshold for acknowledging a sufficient change in the right direction are:

  • Change is more than +4mg/dl in 5 minutes from low alert
  • Change is more than -1mg/dl in 5 minutes from high alert

Smart snoozing

 Keep snoozing if glucose is heading in the right direction

Smart alerting

 Don't alert if glucose is heading in the right direction

Don't alarm during phone calls

Alarms will not sound if they trigger during a phone call.

Suppress alerts if missed readings

Suppress Alerts if missed readings

Level alerts remain active even if there is no signal (sensor change for example, or follower without network). This option allows you to suppress them. Make sure you have a missed alert enabled if you use this feature.

Suppress Alerts if missed readings

 Suppress snoozed and active alerts after predefined period of missed readings

You can define the number of minutes after which you want alerts to stop.

Suppress snoozed and active alerts after .. minutes (minimum 10)

 Suppress snoozed and active alerts after predefined period of missed readings

Notification Channels

With Android 8 and above you can use the notification channels for your alerts. This will allow you to customize notifications at Android level.

Notification Channels

In order to setup this feature, go to Android Settings / Notifications / Apps / xDrip+ and allow sound and vibration.
You'll then be able to decide each notification behaviour. If you have multiple notification and alarms, disable the unwanted ones here.

Ascending Volume settings

Ascending Volume settings

Delay Ascending Volume

You can delay the start of the ascending volume alert without delaying vibration that will start as soon as the alert is triggered.

Delay Ascending Volume

 For ascending volume profile, delay the start of the alert sound by 3 minutes. The vibration (if enabled) starts as soon as the alert triggers regardless of this setting

Ascend to medium

You can limit the maximum volume of the ascending volume alerts and alarms to medium instead of maximum.

Ascend to medium

 When enabled, ascending volume profile will ascend to medium volume instead of maximum

Calibration Alerts

If your sensor requires periodic calibration you can setup xDrip+ to alert you when calibration is due.

You can setup the period between calibrations, sound to be played, etc ...

Calibration Alerts

Calibration Alerts

 Alert when a calibration is requested

Hours between calibrations

 How many hours between calibration requests

Calibration request sound

 Default

Override Silent mode

Even when charging

 Uncheck to not ask calibrations when phone is charging

Repeat Alerts

 Keep alerting if no calibration is performed

Alert Repeat minutes

 20

Initial alert

Initial calibration alert is used when starting a sensor requiring initial calibration: it will trigger when enough good readings are available to calibrate.

Initial Alert

 Play sound when Initial Calibration is requested

Missed Reading Alert

Missed Reading Alert

When relying on xDrip+ to alert you for lows and highs, it is essential to make sure that it is actually receiving BG readings. For this, if you don't have any other alarms, enable this feature for your safety.

Setup is similar to glucose level alerts. The alarm sound has to be defined in Other Alerts (See below). In order to test it, put your phone in airplane mode until it triggers.

☰ Configure Missed Readings

✅ Enable missed reading alert
Alert if no data is received in:
 30  minutes
Select time for alert:

Noisy Readings

NOISY READINGS

If you enable this feature and your sensor supports it, you can setup an alert for noisy readings.

Bad (noisy) Value Alerts

Alert after x minutes of noisy values

 90

Alert snooze

 Number of minutes before raising the same alert after snooze

Reraise alerts before snooze time

 Reraise the alert if not snoozed sooner

Alert reraise time

 Number of SECONDS to pass before raising the same alert

Falling or rising BG

FALLING/RISING BG

You can also setup alerts for fast BG changes and define the 1 minute change triggering value. For example 3 minutes means 15 mg/dl (0.85 mmol/l) every 5 minutes.

BG falling fast

falling rate threshold

 3mg/dl/min (0.17mmol/l/min)

BG rising fast

rising rate threshold

 3mg/dl/min (0.17mmol/l/min)

Alert preferences

ALERT PREFERENCES (FOR THESE ALERTS)

The alerts above and also Missed Readings use the sound defined below.
Some recent Android versions do not ring it unless you use Notification channels.

Make sure to test the alarm

This is an important feature to sleep safely. Reduce the missed readings period and put your phone in airplane mode (no Wi-Fi) to force the alarm to ring.

Persistent High Alert

Persistent High Alert

Instead of a high alert that will trigger as soon as BG reaches the trigger value, you can setup a persistent high alert that will only trigger when BG remains above a setup value for more than a certain time. You can use either xDrip+ High Value or a value you decide for triggering this alert.

Enable

 Notify if above threshold for longer than the time specified below

Threshold: High Value

 When enabled, High value is the threshold.
 When disabled, the threshold is the value defined below.

Forecasted Low Alert

Forecasted Low Alert

You can set an alarm on forecasted low value. This feature will use the momentum (extrapolation of the current BG trend) and not the prediction settings. Forecasted low (min) is the time in which a low will be forecasted (the one that usually displays in yellow on the graph screen).

Forecast Lows will display a message on xDrip+ screen. In order to have an alarm sounds when a low is forecast, enable Raise alarm on Forecast Low.

Forecasted Lows

 Extrapolate data to try to predict lows

Raise alarm on Forecast Low

 Notify when predicted low time reaches threshold
