Nightscout (CGM in the Cloud) is an open source, DIY project that allows real time access to a CGM data via personal website, smartwatch viewers, or apps and widgets available for smartphones.
Nightscout was developed by parents of children with Type 1 Diabetes and has continued to be developed, maintained, and supported by volunteers. When first implemented, Nightscout was a solution specifically for remote monitoring of Dexcom G4 CGM data. Today, there are Nightscout solutions available for Dexcom G4, Dexcom Share with Android, Dexcom Share with iOS, and Medtronic. The goal of the project is to allow remote monitoring of a T1D’s glucose level using existing monitoring devices.
Determining the best way for you to approach setting up Nightscout depends first and foremost on the following:
The following chart offers an overview of the paths available to setting up CGM remote monitoring using Nightscout.
Nightscout has expanded rapidly. To quickly access the information you need, try the resource.
There are multiple smartwatch options for viewing CGM data. With a Nightscout site, options exist for Pebble (all varieties), AndroidWear, and Apple Watch. Learn more about .
The technology is rather simple: your Dexcom receiver continues to work as it always has by reading the glucose level of the T1D who is wearing the sensor/transmitter. The Nightscout system allows you to attach (or pair) a device to the Dexcom receiver that transmits the glucose readings to the Internet, where any web-connected device can view the numbers. It’s that simple.

Whether cabled or wireless, CGM in the Cloud solutions involve a phone paired with a CGM. In the original Nightscout setup, the cabled uploader phone and CGM was referred to as the “rig.” This is the system that the T1D keep with them, in range of the CGM transmitter, to enable the upload of real-time blood glucose data.
The combination of the smartphone Dexcom receiver allows data to be sent to the Internet. CGM levels can then be seen from anywhere in the world. There is no limit to the number of viewers.
During the install process several systems need to be synchronized using configuration menus in several different applications. These systems are required for the system to work. Once those systems are installed and synchronized, your personal website ultimately displays the data from the cloud using an Internet browser. Almost any device that can access the Internet will be able to see this website. The website works on many mobile devices such as tablets, laptops, Mac devices, and on any other web-connected device. Depending on how you set up Nightscout, viewers are also available for Pebble watch, AndroidWear watches, and Apple Watch.

The sole purpose of your specific website is to display the data. Due to the caveats mentioned and for many other reasons, it is important to .
Reading through the step by step instructions for your particular setup before you start will help prepare you for putting everything together and learning how to use the system.
Please note: Many of the resources and documents on this site describe the original Nightscout setup (which involves a cable and an Android). There are wireless solutions now available. Documentation is being added and revised on an ongoing basis.
