Smoke Detector Meross GS559A Wi‑Fi, HomeKit compatible, battery‑operated

Meross GS559AH WiFi Smart Smoke Detector is a photoelectric smoke and overheat sensor designed for home use. It sounds an 85 dB alarm when smoke or high temperatures are detected and can be linked with other Meross alarms so that a single triggered unit notifies all connected devices. The detector is compatible with the Meross app and Apple Home (HomeKit) and can be integrated into a larger system via an optional HUB (sold separately). The package includes the alarm, two expansion bolts and an instruction manual.

Advantages

The detector meets CE EN14604 requirements and carries CE, RoHS and WEEE certifications. It uses two readily available AA batteries (DC 1.5 V × 2) with supplied batteries included in the kit. The unit supports wireless connectivity via 2.4 GHz Wi‑Fi and 433 MHz for device interlinking, and works with SmartThings and Apple HomeKit. Built‑in overheat detection triggers the alarm when temperature rises to the 54–70 °C range.
