LoopFollow FAQs
Pro Tip: Frequent Glucose Alerts
If you are experiencing audible and visible glucose alerts every single minute, disable the LoopFollow > Settings > General > Persistent Notifications slider.
Note: this is completely different from the persistent notifications you may want enabled to see APNS messages returned from real-time responses to remote commands.
Version Compatibility¶
This section consolidates version requirements for LoopFollow to work with Loop and Trio, and provides historical context for how remote control has evolved.
It also lists updates to the method for using Browser Build.
LoopFollow Version 6.0 and newer¶
With the addition of Live Activity to LoopFollow, the build directions for browser build were updated.
- If you use Browser Build, your automatic build will fail until you add the new Identifier, create the
LoopFollow App Groupand include theLoopFollow App Groupin the capabilities for the LoopFollow Identifiers. - Instructions start here: Add LoopFollow App Group
LoopFollow and Loop Compatibility¶
| Feature | Minimum Versions Required |
|---|---|
| Loop Remote Control via APNS | LoopFollow 3.2 or newer; any version of Loop |
| Real-time APNS response from Loop phone | LoopFollow 4.6 or newer; Loop v3.11.1 or newer |
With LoopFollow 3.2 and newer, Loop remote commands include Meal, Bolus and Override control. LoopFollow no longer requires the Nightscout site to be configured with the APNS credentials — Read access for the Nightscout URL is sufficient.
With LoopFollow 3.1 and older, Loop remote commands were limited to Overrides, required the Nightscout site to be configured with the APNS credentials, and required a token with careportal access.
LoopFollow and Trio Compatibility¶
Breaking Change: Trio Remote Command Users
Trio users must have matching versions of LoopFollow and Trio for remote control to work.
- Trio 0.6 (or newer) requires LoopFollow 4.0 (or newer)
- Trio 0.5.1.28 (or older) requires LoopFollow 3.2.11 (or older)
Remote control commands stop working if versions are not matched. You do not need to reconfigure your credentials when upgrading — your existing settings continue to work. However, LoopFollow Browser Build users must update their Identifiers when upgrading from v3.x: see Legacy: Updating from v3.x.
| Feature | Minimum Versions Required |
|---|---|
| Trio Remote Control via APNS | LoopFollow 4.0 or newer; Trio 0.6 or newer |
| Real-time APNS response from Trio phone | LoopFollow 4.0 or newer; Trio 0.6 or newer |
| Nightscout Careportal (Temp Targets only) | Available for all Trio versions |
| Nightscout OpenAPS pill display | Nightscout 15.0.2 or newer with Trio 0.5.x or newer |
With Trio 0.2.x, LoopFollow only supports Temp Targets via the Nightscout Careportal, which requires a token with careportal access. Once updated to Trio 0.5.x or newer, the full Trio Remote Control options are available.
For those following a looper using Trio 0.2.x, the only remote setting option in LoopFollow is Nightscout (Careportal). With this selection:
- The LoopFollow phone sends commands to Nightscout, which then forwards commands to the Trio phone
- The Nightscout display will be updated first
- If there is an issue sending the Careportal request, it might not reach the Trio phone
- After the next Nightscout download, LoopFollow display will reflect whether commands completed the full round trip
APNS Keys Do Not Need to Be in Nightscout¶
With LoopFollow 3.2 and newer, the APNS credentials are entered directly in the LoopFollow app. They do not need to be embedded in the Nightscout site for remote control to work. This simplifies Nightscout configuration, especially for those using a paid Nightscout service.
The APNS credentials only need to be in Nightscout if you also use Nightscout Careportal or the LoopCaregiver app to send remote commands.
