HEIMAN Smart Smoke Sensor Matter-over-Thread (HS1SA-M)

I received the smoke detector very quickly, and installation was extremely easy thanks to the Matter QR code. It connected directly to my Matter-enabled Apple HomeKit setup with a HomePod mini — no additional bridge required.

Only a few days later, the detector passed its first unintentional real-life test in my kitchen with flying colors: as soon as my wife started searing meat a little more aggressively in the pan, the alarm went off immediately and loudly. At the same time, HomeKit also alerted me on my iPhone, both acoustically and with a notification.

Excellent performance — it doesn’t get any better than this.

Needed several attempts to integrate to Apple Home and Home Assistant. Once integrated, it works reliable. Design is OK even if there are more stylish ones out there

This is the first « Matter over Thread » smoke detector. Difficult to find at that time. Works fine with Samsung smartthing using my TV as Thread hub.
Connected but not recognized with Apple Home application and HomePod as Thread hub. Need iOS 18.4 or iOS 19.
