First of all, very important things :
1) Nightscout is not illegal.
In fact, the company Dexcom has been very permissive with the project and has never attacked, or pressured.It has clearly benefited them a lot in other countries, since more sensors and transmitters of the DEXcom are sold thanks to Nightscout.
However, if your official distributor in Spain, Novalab, is not satisfied with what is exposed here, you can contact the forum administration to eliminate this thread at Link (I am not a memberof the same).
2) I am not responsible for absolutely anything:of the things that this thread is spoken.
3) I don't commit to give any support. You should ask for the help for the right channels, which are the official English -speaking Facebook group "CGM in the cloud" ( Link or some other meansunofficial.
If someone puts their doubts here, I will solve them if I have the necessary knowledge and if I feel like it and when I feel like it.
4) All the information and guides that are linking in English, so you will need some knowledge of this language, or someone to help you.

Now let's go in parts.First, what is Nightscout?Its website: Link
Nightscout is to be able to get the data that the Dexcom G4 is measuring, pass them to our mobile (and our mobile to our smartwatch if we want) and that our mobile goes up to our website.From that website you can visualize everything, even make reports.Then other people who know our website, with the mobile browser or with another program can visualize what is on our website, and see it even on their smartwatch.
An example of a website with Nightscout (mine in this case):
List of several functions that the Nightscout website has:
Link
The best without a doubt is the very powerful report tool that brings:
There are several ways to set up the Nightscout tinglado with the Dexcom G4, as we can see here:
Link
1) Dexcom G4 "Normal" , the one we have in Spain: it is necessary to connect the official DEXcom receiver through an OTG cable to the mobile, to be able to pass the data.
It is a pain, since you have to carry the receiver always connected to the mobile by the happy cable.
Example: Link
There are 3D printing covers and be able to wear everything together, it is typical for children.You can download a 3D printable model here Link
How to mount Nightscout with this method:
Link and Link
2) Dexcom G4 Share : As I explain here: Link The difference with ours is that the receiver emits in Bluetooth.This is used for the official receiver to communicate directly with the mobile without cables.More comfortable, but we don't have this option thanks to Dexcom did not want to sell the Share version here.

3) Dexcom G4 +home receptor (xDrip) .We do not need the official receiver.Everything is done through our mobile, including starting the sensor and calibrations.

dexcom G4 + home receptor (xDrip)
I explain in detail this last option, which is the one I currently use.
A photo of what I have mounted: Link
Smartwatch in detail: Link
It is based on what this guy has mounted Link very interesting reading.
The difference is that he uses a pebble smartwatch and I a smartwatch with Android Wear (LG G Watch R).To see what it would be like with a pebble here: Link
So my configuration:
- G4 transmitter in my body - & GT;Send a radio signal every 5 minutes with my blood glucose level.
- Home receptor: caught that signal and transforms it into a Bluetooth signal (that my mobile is capable of understanding) and sends it to my mobile.
- Mobile: Receive the glucose value and show it to me in an app called XDrip.That same app goes up to my Nightscout website.The XDrip app also sends that glucose value directly to my smartwatch.
- Mobile of my partner: through the Nightwatch app, catch what is on my website and show it to the mobile.If my girlfriend had a smartwatch, it would also appear there through the Nightwatch app itself.
We will explain what these two fundamental apps do:
xDrip:
Download: (Always download the last beta) Link
Photo: Link (not mine, the home receptor is the brown box).
This app is the one that makes a mobile phone the home receiver receiver.It is also responsible for uploading our data to our Nightscout website.
In its last beta allows to send what this app shows to our smartwatch, without installing the Nightwatch app.
In this app put the alarms, the calibrations, the sensors begin, statistics are seen ... everything.
Nightwatch:
Download: Link
It has two functions: one is to see the data on a Nightscout website directly in this app, it is more comfortable than walking the browser.You can also put alarms here too, which is ideal for monitoring a small child.
The other function is to send what the app shows to our smartwatch.

Now the theme of the home receptor "XDrip Reciever":
PAGE WITH ALL THE INFO: Link
COMPONENTS AND ASSEMBLY: Link (for those who do not find a valid bluetooth module, this is worth: Link
Detailed assembly video: www.youtube.com/watch?v=yuxcuej9xau
Firmware: Link
Mine is computer science, not electronics, so the home receptor I set up left a little like the ass, and I bought this: Link
Read all the tinglado before asking.
It comes with everything necessary, but one of the pieces without welding with tin, so it is not completely mounted and it is not illegal to sell it.Otherwise he would be selling a medical device and could melt it.
With a low -power and tin welder,You have to finish riding it, it is not difficult.You can ask someone with a skill and some experience.
Things to take into account this XDRIP Kit:
- The battery life is about 50-60 hours.
- It does not come with hole to load it, so you have to open the box every time.
- It is quite large compared to whether you ride yourself.It is the most improvable.
- Every time we change the transmitter we must reprogram it, since it is prepared to be used only your transmitter (before buying it you have to send the type number of your transmitter) to the type.The way of reprogramming it is detailed how it is done in the link that I put above, in "firmware".
- The box is very resistant.
- The obvious quality of its construction gives me a lot of confidence that it will not fail.
The guy is working on a much smaller model.This has been his first model and now he will improve it.I look forward to a smaller version, for now with this luxury strip.
------------------------------
Important on the subject of the home receptor:
It will not always show exactly the same as the official receiver.Many times yes, but not always.
This is because the XDrip algorithm is not exactly the same as that of the official receiver.XDrip is based a lot on the RAW Data (raw data) and the official receiver not so much.
It is explained here: Link
Summarizing a lot: the dexcom transmitter reads that you have 50 glucose.XDRIP shows you 50 and the official receiver also.The next reading at 5 minutes is 80. XDrip directly shows you 80, because it is what you have read, it is the base data without processing or interpreting.
On the other hand, the official receiver may seem that a change of +30 in 5 minutes is a lot, and it shows you something intermediate instead of 80, such as 70. And if you continue to see things that you do not like it shows you the "???? "
That is, the official receptor softens the glycemia curves to give a fewer sierra and softer tooth.
What seems demonstrated is that with Raw Data Pillas before the rapid drops that end up in Hicm, since you see faster when it begins to go down much than with the official receiver.Many people prefer Raw data.
The problem is that it gives you a scare when the "Compression Low" passes that is to compress the transmitter for example when sleeping and that you are suddenly at 150 and reads you for example 50. The official receiver if it is an isolated reading possibly ignore it or ignore itHe puts you "???", but with the landlord you will see it very clear.Not everyone is up to Compression Lows.
At 7 you have an example of what I mean, it happened to me: Link
With the official receiver you can compare and see the differences.
-----------------
Home receptor pros:
With the XDrip app on the mobile you can put all the alarms you want, it is a pass.
I have those from low to 70, and another at 80. More than 55 that is default and cannot be deactivated.
And I have 250 and 300.
With the sounds you want each one, and you can choose whether or not you want to sound with the mobile in silence.
The smartwatch vibrates you in alarms.It's brutal.
--------------------------------------------------------------------------------------
Tip: Go in parts:
First we assure ourselves that the whole issue of the home receptor works well, that the XDrip app is well configured and show everything well on the mobile.
Then if we have a smartwatch we install Nightwatch and configure everything well to see the glycemia on the mobile.
When everything is operational and without problems, we already put ourselves with the Nightscout theme.

I will update and improve the guide tomeasure that things arise.
