Onvis Motion Sensor SMS2

The Onvis Motion Sensor SMS2 combines PIR motion detection with temperature, humidity, and light level sensing in one Thread-enabled device for Apple HomeKit. This multipurpose sensor communicates through Thread protocol for fast, reliable reporting, with Bluetooth fallback for compatibility. The sensor requires no hub—it connects directly through a Thread border router.

Motion detection uses passive infrared sensing with adjustable sensitivity through the Onvis app. The integrated light sensor enables automation based on ambient brightness, while temperature and humidity readings appear in Apple Home for environmental monitoring. Battery life reaches approximately one year from a CR2032 cell.

HomeKit automations can trigger lights on motion, adjust climate when humidity spikes, or send alerts based on detected activity. The scheduled detection feature enables motion sensing only during specific hours, reducing unnecessary notifications. For HomeKit users wanting a comprehensive sensor combining motion, environment, and light detection through Thread, the SMS2 provides multiple sensing capabilities in one compact device.
