Apple Watch with a Nightscout follower
A watch needs a compatible follower app; Nightscout Pro does not pair directly with the watch. Nightguard is one named iPhone/Apple Watch client for Nightscout.
Setup
- Confirm fresh readings in the Nightscout browser view.
- Install the current supported Nightguard app on the iPhone and configure its Nightscout site address with the authenticated viewing method supported by that version. Use a dedicated readable token where available.
- Confirm a new value and timestamp on the iPhone before adding the watch layer.
- Install/enable its Apple Watch app using the iPhone Watch app, then open it on the paired watch.
- Add the Nightguard complication to a compatible watch face if offered. Compare its value and age with the phone and Nightscout.
The exact app settings and watch-face choices can vary by version. Use the developer’s current configuration walkthrough rather than copying credentials into an unrelated calendar or display app.
Stale watch data
If the phone is stale too, investigate its Nightscout connection. If only the watch is stale, check pairing, connectivity and the app’s watch/background behavior. A complication can show cached data and its refresh schedule is not a guaranteed live alarm path.
