So I recently acquired access to my real time Dexcom data thanks to this NightScout Bridge and a script written by Ben West Dexcom Bridge.
Anyway I set up a webpage that auto-refreshes every minute and updates the browser tab to show my BG and a trend arrow. It has actually been pretty nice to see my BG in my browser tab while I work so I don’t have to constantly check my phone.
All this to say, would anyone be interested in having my server host the same thing for them? I could create some sort of login system that you’d enter your data into and then be able to see your real time data in the browser tab.
Here is a link to the webpage I made. The only cool part is the browser tab at the top. The ‘last 10 readings’ thing is just w/e
Also don’t judge me for BG being high, I just had a big mexican craving and I ate 3 tacos…
*Edit: I went ahead and made a basic login system. Anyone should be able to try this out (as long as you have a Dexcom w/ share/follow capabilities.
I have seen others report something similar, but not sure technically how they do it.
I tend to look at my dexcom when it alarms, or about to eat, drive, or exercise. So not helpful for me, but I can see how others, even parents may be interested.
I totally get that. I’ve been on the more obsessive side lately… Probably not healthy mentally…
Fetching the Dexcom data is actually pretty easy.
You basically talk to their servers as if you are the follow app.
It takes two requests to Dexcom, the first provides all of the credentials (username, pw, app id, etc…) If the credentials match what they expect then they return a session ID. You then take this temporary session ID and use it in the second request to return your BG values and trend data.
Hi @apmeyer27, I would be interested in this, but have no idea how to implement it. Would a second person also be able to see the same data on their individual browser if they have the login creds (a share scenario)?
Yea anyone with the login credentials would be able to see it. Of course, I haven’t implemented the login thing yet but I was going to if anyone wanted this.
Let me do a little research tonight and tomorrow and I’ll figure it out
Okay here are the steps. No guarantees if it doesn’t work right away. I’m sure there are bugs because I built this whole system in the past 3 hours.
Pre-requirements:
Make sure you know your dexcom account username and password. I’d test this out on Dexcom’s website by logging out of your account and logging back in.
Make sure you have at least 1 Dexcom Share follower, If you don’t have one, you can always invite yourself and accept it.
Setup
Sign Up here (This will be the username and password for viewing your data)
After filling out the sign-up form you should be redirected to a ‘settings’ page. If you aren’t here is the link. (This will be where you put your Dexcom username and password)
Once your dexcom credentials are submitted you should be redirected to a live feed of your BG. (you might get an error here if the dexcom credentials didn’t work properly. if this happens I’ll have to figure out how to fix it tomorrow)
I’m an Electrical Engineer at Siemens. We design PET scanners. However, I’m also back in school for a masters in CS at Georgia Tech (online) with a focus in Machine Learning. I’m in my 4th class out of 10 right now.
I’m always wanting to use my CS background to contribute to Diabetes, it can just be hard to find problems that aren’t being tackled by the large companies.
So if you ever have ideas, I’d love to implement them.
I am on the computer all day for work. Work often extends into night.
So anyway, having a small browser open in the corner of one of my monitors that provides a continuous and updating real-time cgm is awesome. Being able to glance and see the last 10 readings plus the last 10 “changes” makes it trivial to tell at a glance where the BG is, the direction it is going and the rate that it is moving.
I am obviously aware that Dexcom has the Follow app and I have that and use it on a tablet also. And the Follow has the graph which is certainly nice. But I am finding that I am using the tablet with Follow less and this app more. I really like the data on this app.
This is really useful !!!
Thanks so much for taking the time to build it and make it available to others.
I would love this! Unfortunately I have a Canadian G4 receiver, which is not Bluetooth-equipped. And I’m not tempted to upgrade when I can get up to 47 days out of one sensor. So I’ll just wallow in my envy.
