Notes

A smart smoke detector adds app alerts and self-testing to a life-safety device. Minor fixes (battery, cleaning per instructions) can be reasonable, but safety and sensor age matter more than repair cost.

Replace when the unit reaches the recommended replacement age, shows repeated nuisance alarms after cleaning, or has sensor errors that recur. If connectivity fails but local alarming still works, you may keep it temporarily, but replacement restores full alerting and reduces risk of a silent sensor failure.
