What is the Nightscout project?
Nightscout (CGM in the Cloud) is an open source,
DIY project that allows real time access to a Dexcom G4 CGM from web browsers via smartphones, computers, tablets, and the Pebble smartwatch. The goal of the project is to allow remote monitoring of the T1D’s glucose level using existing monitoring devices.

THIS IS THE NIGHTSCOUT PROJECT
Note: There is no support or any warranty of any kind. The quality and performance of the project is with you if you choose to use it. This is a project that was created and is supported completely by volunteers.
How Does It Work?
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 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.

What Does It Look Like?
This is the system that the T1D will continue to keep with them. It is referred to as the “Rig” throughout this guide. There are countless configurations of the cables that connect the Dexcom receiver to the uploader device.
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.
With these components, the CGM levels can be seen from anywhere in the world.
What’s It Like In Action?
What Does It Cost?
The minimum cost for the initial setup is approximately $100 for a fully working system (click here for details). Some users have been able to find components on sale and have setup for about $75. If you choose to add optional accessories to customize your Rig, you can spend much more, from $50 more to $350 or more. The on-going monthly cost is anywhere from $0 (free) to much more, again, depending upon the setup options you choose.
What Do I Do Now?
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 not rely on this for therapy .
Reading through the step by step instructions before you start will help prepare you for putting everything together and learning how to use the system.
