Before You Service or Replace One
- Generation — Gen 1 vs Gen 2 vs 3rd gen — battery type and reset steps differ.
- 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.

Error Codes
Ring products report faults through the Ring app Device Health and device event history — not traditional numeric keypad codes like hardwired alarm panels.
How to read status
- Open Ring app → Menu → Alarm (or device tile for cameras).
- Tap Device Health or the device — note Offline, Tampered, Low Battery, Open.
- Tap the fault for Ring's suggested steps and linked support articles.
- For hub issues, check Base Station / Alarm Pro connectivity first — many "sensor offline" faults are mesh or hub internet issues.
