Notes

A smart smoke/CO detector is a safety device first, and a smart-home gadget second. The decision to repair or replace should be conservative: any reliability concern matters.

Common issues include sensor chamber contamination (dust/grease), aging backup batteries, and connectivity or speaker faults that reduce alert effectiveness. Repair can make sense for non-safety-critical issues like intermittent Wi-Fi connection (if local alarming still works), cleaning-related false alarms, or a replaceable battery/power issue when the unit is still within its service life.

Replace is strongly favored if the detector is near end-of-life, fails self-tests, or shows repeated sensor errors-because sensing components degrade and are not meaningfully serviceable by consumers. The "cost" of failure is high, so err on the side of replacement for anything uncertain.
