How to Connect Dexcom Share to GlucoHome
Getting your Dexcom CGM data into GlucoHome takes less than 5 minutes. This guide walks you through the complete setup — from enabling Dexcom Share to seeing your first glucose reading in the GlucoHome dashboard.
What you'll need
- An active Dexcom G6 or G7 CGM sensor
- The Dexcom app installed on your phone with Dexcom Share enabled
- A Google account, or the guest option in this browser
- A few minutes to connect Dexcom Share
Important: Dexcom Share must be enabled
GlucoHome accesses your glucose data through the official Dexcom Developer API, which requires Dexcom Share to be enabled in your Dexcom app. If you haven't enabled Share yet, follow the steps below.
Step 1: Enable Dexcom Share
Open the Dexcom app on your phone. Tap the Share icon in the bottom navigation (it looks like three people). If this is your first time using Share, you'll be prompted to set it up:
- Tap Get Started
- Accept the Dexcom Share terms and conditions
- You can skip adding followers for now — GlucoHome doesn't use the follower system; it connects via the Dexcom Developer API
- Share is now enabled on your account
Step 2: Sign in to GlucoHome
Visit glucohome.id and click Get started free or Sign in. You can sign in with Google (OAuth — a sign-in hand-off so we never see your Google password) or start in this browser without Google.
If you use Google, click Continue with Google and approve the sign-in screen.
Step 3: Connect your Dexcom account
Once you're signed in to GlucoHome, you'll see a prompt to connect your Dexcom. Click Connect Dexcom and enter your Dexcom Share details.
- Enter your Dexcom username and password (the same credentials you use in the Dexcom app)
- Dexcom will ask if you want to grant GlucoHome access to your glucose readings. Click Authorize
- You'll be redirected back to GlucoHome automatically
Connection uses HTTPS
The Dexcom connection runs over HTTPS (encrypted in transit). Readings are then stored in the GlucoHome cloud database so the dashboard can show them. You can disconnect Dexcom in settings. Keep using Dexcom's own alarms.
Step 4: View your glucose data
Once authorization is complete, GlucoHome immediately fetches your latest glucose readings from the Dexcom API. Within a few seconds, you'll see:
- Your current glucose reading and trend arrow
- A real-time glucose chart showing the past 24 hours
- Your Time-in-Range percentage
- Trend views that show where recent readings are heading
New readings sync automatically every 5 minutes — matching the cadence of your Dexcom sensor. You don't need to manually refresh the dashboard.
What happens next?
With your Dexcom connected, GlucoHome begins building your glucose profile. Over the first few days, the AI learns your patterns and can start offering predictive insights — like alerting you when you're likely to go low in the next 30 minutes based on your current trajectory and historical data.
You can now start logging meals, tagging exercise, and exploring the AGP chart to see your glucose patterns across different times of day. If you're working with an endocrinologist, they can also access your data through the GlucoHome Provider Portal (if they've been granted access).
Troubleshooting
I don't see my glucose data after connecting
Make sure Dexcom Share is enabled in your Dexcom app. If Share is off, the Dexcom API won't return any readings. Also check that your sensor is active and transmitting — if your Dexcom app isn't showing readings, GlucoHome won't be able to fetch them either.
The connection keeps failing
Double-check that you're using the correct Dexcom username and password. If you recently changed your Dexcom password, you'll need to reconnect. Visit the GlucoHome settings page and click Reconnect Dexcom.
Can I use GlucoHome if I only have Dexcom Follow access?
Not currently. GlucoHome requires you to be the primary Dexcom account holder (the person wearing the sensor). We're exploring follower support for parents and caregivers in a future release.
