Presence Sensor Tellur TLL331552 WiFi White — wireless presence detector, white

Tellur TLL331552 WiFi White is a compact wireless presence sensor designed to detect human presence and movement in indoor environments. The device connects to a local WiFi network to integrate with compatible smart home systems and automation platforms, enabling actions such as switching lights, adjusting climate controls, or triggering security routines based on occupancy. Its mains-independent design allows flexible placement in rooms, corridors, offices and other interior spaces where occupancy-based automation is required.

Advantages

The sensor offers wireless WiFi connectivity for straightforward integration with home automation systems without the need for additional hubs. Its compact white housing permits discreet installation in a variety of interiors. Mains-independent operation allows placement away from fixed power outlets, increasing installation options. The device is tuned to detect typical human movement and presence patterns for reliable automation triggers while helping to reduce energy consumption through occupancy-based control.

Suitable for

• Automating indoor lighting based on occupancy
• Heating, ventilation or air conditioning adjustments in occupied zones
• Office and corridor presence detection to optimize energy use
• Integration into smart home scenes and security routines

Key specifications

• Wireless connectivity: WiFi for direct integration with compatible smart home systems
• Detection type: presence and motion detection for indoor use
• Color and finish: white compact housing suitable for visible interior mounting
• Power: mains-independent (battery or internal power source) for flexible placement
• Typical installation locations: rooms, corridors, offices and similar indoor spaces

How to use

Install the sensor in a location that provides clear line of sight to the monitored area and at a height recommended for the specific coverage required. Connect the device to the local WiFi network using the manufacturer's setup procedure, then integrate it into the smart home or automation platform of choice. Configure detection sensitivity, timeout and automation rules within the controlling app or platform so that lights, HVAC or security actions trigger appropriately when presence is detected or when the area becomes vacant.

Recommendations

Position the sensor to avoid direct exposure to large windows or strong heat sources that may affect detection accuracy. Test and adjust sensitivity and timeout settings after installation to balance responsiveness and false triggers for the specific environment.
