Hombli HBSA-0109 Wireless White Photoelectric Reflection Detector

The Hombli HBSA-0109 is a wireless photoelectrical reflection smoke detector designed for home use. It emits a loud alarm when smoke is detected and sends instant notifications to your phone via the Hombli app. The unit has a compact, ultra-slim design, runs on an internal 3V lithium battery with an estimated 10-year life, and is simple to install using a magnetic mount with 3M tape or a single screw.

Advantages

The device provides both an audible alarm of over 85 dB and push notifications to your smartphone so you are alerted whether you are at home or away. Weekly automatic self-tests of the battery and sensor ensure ongoing functionality and the app displays current battery status and diagnostic alerts. False alarms can be muted remotely through the app or by pressing the integrated button; normal monitoring resumes automatically 10 minutes after muting. The slim, minimal design fits most interiors and the magnetic mount enables quick installation and easy removal for maintenance.

How to use

Connect the device to your home Wi‑Fi and add it in the Hombli app. When smoke is detected the detector will sound a loud alarm and send an immediate push notification to your phone. If the alarm is accidental, mute it via the Hombli app or press the integrated button; the detector will resume automatic checks after 10 minutes. Monitor battery and device status in the app and follow on‑screen guidance if the app reports a problem.

Recommendations

Install one detector in each sleeping area and on every floor of the home, following local safety regulations. Test the device after installation and check app notifications regularly. Keep the detector free of dust and clean it periodically by removing it from the magnetic mount; replace the unit if it fails self-tests or the app indicates an irreparable fault.
