Compatibility

sugardash displays glucose data from supported CGM and follower services. It does not connect directly to CGM sensors, insulin pumps, or automated insulin delivery systems. Instead, it retrieves glucose information that is already being shared to the internet through services such as Dexcom Share, LibreLinkUp, Nightscout, or Twiist Insiight.

Understanding how this data moves from your body to sugardash can help determine whether your setup will work.

How Glucose Data Reaches sugardash

The process usually looks like this:

1. CGM Sensor - Your CGM sensor measures glucose levels in your body.
2. Receiver Device - The sensor sends readings to a phone, receiver, pump, or connected diabetes system.
3. Cloud Sharing Service - That system uploads glucose data to a service such as Dexcom Share, LibreLinkUp, Nightscout, or Twiist Insiight.
4. sugardash - sugardash connects to your Wi-Fi network and retrieves the glucose data from one of these services to display it on the screen.

Because sugardash relies on these online services, your glucose data must already be reaching a compatible cloud or follower service.

Dexcom Compatibility

sugardash works with users of:

  • Dexcom G6
  • Dexcom G7
  • Dexcom One+

sugardash retrieves glucose readings using Dexcom Share services.

Dexcom systems allow the sensor to connect to up to three devices simultaneously, which makes many setups compatible with sugardash.

For example:

  • If your Dexcom sensor connects to an insulin pump, it can still connect to a smartphone running the Dexcom app.
  • As long as the Dexcom app is connected and sharing data through Dexcom Share, sugardash can retrieve that data.

A smartphone running the Dexcom app is required for sugardash to work with Dexcom.

Twiist Insiight Compatibility

sugardash works with Twiist users whose glucose data is visible through Twiist Insiight.

To use Twiist with sugardash, you need a Twiist Insiight follower account that can already see the person’s current glucose data. During setup, sugardash signs in with that Twiist Insiight follower account and retrieves the glucose data available to it.

Because Twiist data depends on the Twiist user’s phone syncing through Wi-Fi or cellular:

- If the Twiist Insiight app shows current glucose data for the follower account, sugardash should usually be able to display it.
- If Twiist Insiight is not receiving current data, sugardash will not be able to show current readings either.
- If one follower account follows more than one person, sugardash will ask you to choose which person to display.

sugardash does not control the Twiist pump, change insulin delivery, or send treatment commands. It only displays glucose and status information made available through Twiist Insiight.

When Twiist provides additional status details, sugardash may also show information such as active insulin, active carbs, pump battery, cassette amount, basal or loop state, and recent bolus details. Some details may be unavailable even when glucose readings are working.

FreeStyle Libre Compatibility

sugardash works with FreeStyle Libre systems that share data through LibreLinkUp.

Libre setups typically require the sensor to be connected directly to a smartphone running the Libre app, which then shares data through LibreLinkUp.

Unlike Dexcom, Libre sensors generally cannot connect to both a phone and an insulin pump at the same time.

Because of this:

- If your Libre sensor is connected directly to a pump instead of a phone, LibreLinkUp may not receive glucose data.
- Without LibreLinkUp data, sugardash will not be able to display readings.

In most cases, Libre users can use sugardash when their sensor is connected to a phone that shares data through LibreLinkUp.

Other CGMs Using Nightscout

Many sugardash users have CGMs that are not Dexcom or Libre.

In these cases, they often use Nightscout, an open-source project that allows glucose data from many systems to be shared online.

If you are able to view your glucose data in Nightscout, sugardash can usually display that data as well.

Some CGM systems people have used with sugardash via Nightscout include:

  • Eversense
  • Stelo
  • Medtronic
  • Other compatible Nightscout integrations

Because Nightscout is an independent open-source project, we recommend visiting the Nightscout community documentation to learn more about setup options.
