Security considerations

Besides reporting Nightscout can also be used to control AAPS. I.e. you can set temp targets or add future carbs. This information will be picked up by AAPS and it will act correspondingly. Therefore it is worth thinking about securing your Nightscout website.

Nightscout settings

You can deny public access to your Nightscout site by using authentication roles.

AAPS settings

There is an NS upload only (no sync) function in AAPS settings. By doing so AAPS will not pick up changes done in Nightscout such as temp targets or future carbs.

  • Tap 3-dot menu on top right corner on your AAPS homescreen.

  • Select “Preferences”.

  • Scroll down and tap “Advanced settings”.

  • Activate “NS upload only

Nightscout upload only

Further security settings

Keep your phone up to date as described in safety first.

Manual Nightscout setup

It is assumed you already have a Nightscout site, if not visit the Nightscout page for full instructions on set up, the instructions below are then settings you will also need to add to your Nightscout site. Your Nightscout site needs to be at least version 10 (displayed as 0.10…), so please check you are running the latest version otherwise you will get an error message on your AAPS app. Some people find looping uses more than the azure free quota allowed, so heroku is the preferred choice.

  • Click your App Service name.

  • Click Application settings (azure) or Settings > “Reveal Config Variables (heroku)

      • PUMP_URGENT_BATT_P = 26

Semi-automated Nightscout setup

Fellow looper Martin Schiftan offered a semi-automated Nightscout setup for many years free of charge. As number of users increased so did cost and therefore he had to start asking a small fee starting October 2021 - starting at €4,17 per month.


  • You can install Nightscout with a few clicks and use it directly.

  • Reduction of manual work as Martin tries to automate the administration.

  • All settings can be made via a user-friendly web interface.

  • The service includes an automated basal rate check using Autotune.

  • The servers are located in Germany and Finland.

An alternative would be - starting at $11,99 per month.
