- Dexcom G7, Dexcom G6, Dexcom ONE+
- Sign in with
- your normal Dexcom account (not Dexcom Follow)
- Updates
- A new reading every 5 minutes, when Dexcom uploads it.
- Not supported
- Dexcom ONE (the original); Stelo
Dexcom ONE and Stelo don't upload readings to Dexcom Share, so there's nothing for Sweet Dreams to read.
How to connect Dexcom to Sweet Dreams
Already have a follower in Dexcom Follow? Skip to the last step.
- Open the Dexcom app and tap the Share icon to turn on Dexcom Share.
- Invite at least one follower. Your own email address works. Dexcom doesn't send readings to its servers unless someone follows you, so this step is required even if you only want to see your own data.
- In the follower settings, make sure the follower can see your trend graph.
- Accept the invitation in the Dexcom Follow app. Download it first if you don't have it.
- In Sweet Dreams, choose Dexcom and sign in with the wearer's Dexcom account, not the Dexcom Follow account.
Good to know
- Signing in for a child or other dependent? Use their Dexcom username, not your email.
- If your username is a phone number, include the + and country code with no spaces, for example
+447700900123. Switching to G7 sometimes changes a username to a phone number. - Getting a new phone can reset follower access. If readings stop, check Share still has a follower.
- Some people have two Dexcom accounts. Check the profile page in the Dexcom app matches the account you sign in with.

Common questions
Does Sweet Dreams work with Dexcom ONE or Stelo?
No. Neither uploads readings to Dexcom Share, which is where Sweet Dreams reads them from. Dexcom ONE+ is supported.
Why do I need a follower if I only want to see my own readings?
Dexcom only sends readings to its servers when Share has at least one follower. Inviting yourself counts.
Do I sign in with Dexcom or Dexcom Follow?
Dexcom: the sensor wearer's own account. Dexcom Follow logins won't work in Sweet Dreams.
Free on the App Store for iPhone, Apple Watch, iPad and Apple silicon Macs.
