Before You Service or Replace One

- Hub online — Base Station must show connected in app before diagnosing sensor.
- Range — distant devices may need Range Extender, not a new sensor.
- Tamper — cover fully closed before declaring hardware fault.
- Monitoring mode — Practice/disarmed modes affect whether alarms dispatch.

Troubleshooting
Quick diagnostic flow
- Confirm exact model/generation on label matches official setup article.
- Verify Ring app Location matches physical site and you have owner/shared access.
- For alarm devices: confirm Base Station / Alarm Pro online before replacing sensors.
- Read Device Health — resolve Tampered/Low Battery before diagnosing Offline.
- For cameras/doorbells: test Wi-Fi RSSI at mount — not at router.
- Power-cycle device and hub/router if fault persists after battery swap.
Symptom-based fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Offline immediately after install | Enrollment incomplete | Remove device; factory reset; add within 3 m of hub (alarm) or good Wi-Fi (video) |
| Intermittent offline | Range or power | Range Extender (Z-Wave); Chime Pro or mesh Wi-Fi (video) |
| Tampered won't clear | Cover or bracket | Reseat cover; tighten mount; check tamper pin |
| Low battery returns quickly | Wrong battery or cold | Official battery SKU; replace all cells if multi-cell |
| Alarm won't arm | Open fault | Device Health list — close/bypass per user policy |
Testing checklist
| Test | How | Pass criteria |
|---|---|---|
| Device Health | Ring app → Alarm Devices | No Offline/Tampered/Low Battery |
| Open/close (contact) | Open door/window | App event; arming blocked if configured |
| Motion walk | Walk test in Away mode | Motion event logged |
| Tamper | Open device cover | Tampered shows; clears when closed |
| Range | Final mount location | Device stays online 24+ hours |
After replacement
Remove old device from app, enroll replacement, update device name, run health check, and notify monitoring subscriber if professional monitoring is active.
