Heiman Occupancy Sensor Matter-over-Thread

The Heiman M1-M occupancy sensor is an intelligent motion detector with light intensity measurement that is based on the Matter protocol and integrates seamlessly into modern smart home ecosystems. The Matter over-thread technology ensures a stable mesh connection that reliably networks devices from different brands. The sensor is energy-efficient, responds precisely, and enables secure automation of lights and scenes.

Highlights

• Matter-enabled: Compatible with numerous smart home ecosystems.
• Matter over-thread: Powerful, stable mesh connection.
• Automatic threshold adjustment and temperature compensation: Minimizes false alarms and maintains sensitivity to temperature fluctuations.
• Motion detection and brightness measurement: Detects presence and ambient light - ideal for automatic light in the dark.
• LED status display: Two-color LEDs (red/green) clarify network status and alarms.
• Tool-free installation: Easy to attach to the wall or ceiling.
