Before You Service or Replace One

- Hub/panel online — 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.
