Which glucose sensors work with Ask My Glucose?

The entire current FreeStyle Libre lineup (Libre 2, Libre 2 Plus, Libre 3, Libre 3 Plus) through LibreLinkUp sharing, and the Dexcom lineup (G6, G7, G7 15-Day, Dexcom ONE and ONE+) through Dexcom Share. If your sensor shares to the LibreLinkUp or Dexcom Follow apps, it works — no extra hardware.

How do I ask Alexa for my blood sugar?

After linking your account, say: 'Alexa, ask my glucose what is my level.' Any Echo in your home answers with your latest reading, the trend, and how fresh the reading is.

Does it work for parents and caregivers?

Yes — because it uses the same follower sharing as LibreLinkUp and Dexcom Follow, a parent or caregiver can link a loved one's sensor and ask any Alexa in the house for their number. That includes remote scenarios: a parent at home while their child is at school, or adult children following an aging parent in assisted living.

Can I check my glucose at night without waking anyone?

Yes. With Alexa's Whisper Mode, whisper your question in the dark and the Echo whispers your reading back — no phone screen lighting up the room, no waking your partner or children. Parents following a child's CGM can check overnight from their own bedroom.

Does Ask My Glucose work with Apple HomePod or Siri?

HomePod and Siri support is coming soon via Siri Shortcuts, using the same account on HomePod, iPhone, and Apple Watch. Alexa support ships first.

Q: Is Ask My Glucose a medical device?

No. Ask My Glucose is an informational convenience only, never a basis for treatment decisions. Always confirm on your reader or receiver. Readings may be delayed or unavailable.

Wear a Dexcom G6 or G7? Ask any Echo for your current reading and trend, spoken out loud — no phone in hand required.

How it works

Ask My Glucose reads the glucose you already share through Dexcom’s Share and Follow system, then makes it available to Alexa. We never touch the sensor — we read the number your Follow account already receives and speak it when you ask.

Then it is just a question away: ‘Alexa, ask my glucose what is my level,’ and you hear the reading, the trend, and how recent it is.

What you can ask

Everyday phrases:

‘Alexa, ask my glucose what is my level’
‘Alexa, ask my glucose for my daily summary’
‘Alexa, ask my glucose which sensor am I using’
On Alexa+, say ‘Alexa, open my glucose’

Frequently asked questions

Which Dexcom sensors work?

Dexcom G6 and G7 (including the G7 15-Day), shared through Dexcom Share to a Dexcom Follow account.

Which login do I use?

Your Dexcom Follow account — the follower login, not the wearer’s primary Dexcom app login. Our setup guide shows exactly which credentials to enter.

How current is the reading?

As current as Dexcom Share provides. Every answer includes how many minutes old the reading is, and stale readings are flagged rather than spoken as current.

Is it a medical device?

No — it is an informational convenience. Always confirm on your Dexcom receiver or app and never dose based on it.
