GlucoLamp-XXXX
The password is printed on the label on the bottom of the lamp.
Open the Setup Page
A setup page should open automatically in your browser after connecting to the hotspot.
If nothing appears after 10 seconds, open your browser and type directly into the address bar:

Enter Your Home WiFi
In the portal, tap Scan Network, select your network (SSID), enter your password, and follow the on-screen instructions.

Lamp shows solid white and nothing changes
Solid white means a boot error or failed WiFi connection. Unplug and replug. If it persists, factory reset (see below) and set up again.
WiFi Setup
Can’t find GlucoLamp-XXXX in WiFi list
The hotspot appears a few seconds after powering on the lamp. Unplug and replug, wait 30 seconds then check your WiFi list again.
Config page at 192.168.4.1 won’t open
Confirm you’re connected to GlucoLamp-XXXX (not your home WiFi). On Android, tap Stay Connected when prompted. Type 192.168.4.1 directly into the address bar. Don’t search for it.
Lamp won’t connect to home WiFi after saving
- Password: WiFi passwords are case-sensitive.
- 2.4 GHz only: GlucoLamp doesn’t support 5 GHz. Use your router settings to identify the 2.4 GHz band.
- Distance: Keep the lamp close to the router during first setup.
Glucose Data
Connected to WiFi but no glucose colour showing
First confirm your CGM app shows a live reading. Then:
- Wait up to 10 minutes; the first sync takes a moment
- Reconnect to the hotspot (10-sec reset) and re-check your credentials
- Check your router’s device list to confirm GlucoLamp has internet access
Lamp was working but stopped updating
- Sensor expired. Start a new session in your CGM app
- CGM account password changed. Update credentials via the config portal
- Brief internet outage. The lamp reconnects automatically
Dexcom
Dexcom: Login failed or authentication error
- Verify your credentials at
dexcom.com - If you use Sign in with Google / Apple, set a standalone Dexcom password at dexcom.com first
- Try the other region (US vs International)
Dexcom: Login works but no data appears
In the Dexcom app confirm: (1) Share is ON, and (2) at least one follower is added. Also check you have an active sensor session.
Freestyle Libre
Libre: Login failed
Ensure you’re using your LibreLinkUp follower account credentials, not your LibreLink sensor account. Verify you can log in to the LibreLinkUp app with those details.
Libre: “No patients found” after login
The connection isn’t active yet. In LibreLink → Connected Apps → LibreLinkUp, status must show Active (not Pending). Accept any pending invitation in the LibreLinkUp app.
Nightscout
Nightscout: Cannot connect
Open your Nightscout URL in a browser. If it doesn’t load, the server is down. Free-tier hosts (Render, Railway) may sleep, so just open the URL to wake it. URL must start with https:// and have no trailing slash.
Nightscout: 401 Unauthorized
The API Secret is wrong. Re-copy it exactly from your environment variables; it’s case-sensitive. For token auth, append ?token=YOUR_TOKEN to the URL and leave the API Secret blank.
