Overview
Wiring into household power with a lithium battery backup, this Kidde smart alarm senses smoldering fires with a photoelectric sensor and sends alerts to phones over Wi-Fi. A voice announces the hazard while an LED ring shows status.
Households get phone alerts for smoke even when away, plus app readings on humidity, temperature and air compounds. The listing mentions carbon monoxide in places, but the sensor type is photoelectric smoke, so do not count on it as a CO alarm.
Who it's for
Homes with existing hardwired alarms where someone wants alerts while away suit this unit. Renters without wiring need a battery smart alarm.
Pros and cons
- Phone alerts over Wi-Fi
- Voice says the hazard type
- Battery backup lasts the alarm life
- LED ring shows status
- Needs hardwired power
- CO sensing unclear in listing
- Remote alerts depend on Wi-Fi
Performance notes
Detection relies on the photoelectric sensor, which responds to visible particles from smoldering fires. Alerts reach phones through Wi-Fi, and the hardwired interconnect sets off linked Kidde alarms together.
