The Nightscout application has built in alarms to alert you when glucose levels are consistently below 80 or over 180. One or two values above or below those limits will not trigger the alarm until consistent hi/low readings have been obtained for several readings.
The alarm screen looks like this – the bgl will be surrounded by a red box:
To DISMISS the alarm – click in the red box and you will see a list of times. Select the amount of time to silence (delaying) the alarm. This is completely up to you and you assume all the inherent risks that go with making any of the selections.
The alarm levels are set in the code. If you have the skills, since it is open source code, then you can edit to your own specifications at your own risk.
To invoke the alarms on cell phones, make sure to click on the “alarm” icon in the upper right corner. Clicking on the icon does not turn it off/on.
You must change your phone’s settings to never sleep / lock. The active window MUST be left open to the azure website. There is a setting on the page (click on the Gear icon in the upper right) to enable “night mode” which dims the screen from 10pm to 6am (based on your phone’s time setting).
The alarms do not seem to work consistently with browsers on iPhones – some users report better results using Puffin or Dolphin browsers
