Every day. In every room.

Peace of Mind, Built In.

Presence Without Cameras.

Detects presence using radar, not cameras. No images. No recordings. No watching.

Air You Can Trust.

Monitor temperature, humidity and air-quality trends with the built-in BME688, including estimated CO₂ and VOC values. Add the optional SCD40 for direct CO₂ measurements.

Feedback When It Matters.

Control the LED and buzzer with Homey Flows or Home Assistant automations. Choose when your sensor provides a visual or audible alert.

Privacy, By Design.

Sensor readings stay on your local network, with direct integration into Homey Pro or Home Assistant. No sensor cloud account or subscription is required.

Understands space, not just motion.

mmWave Presence Sensing

Advanced mmWave radar continuously tracks presence for up to three people simultaneously, including their position, distance, and movement. This allows the system to understand where someone is in a room, not just that someone moved.

With support for three configurable detection zones and one exclusion zone, you can precisely control where presence should trigger automations, and where it should be ignored. Fast, continuous updates ensure detection feels instant, stable, and reliable, even when people move slowly or remain still.

Clear insight, right out of the box.

Air Quality Intelligence

Built-in air quality sensing continuously monitors eCO₂, VOCs, IAQ, and gas resistance, giving you real-time insight into the air you breathe. Changes in air quality are detected early, helping you respond before comfort or focus is affected.

For applications where absolute accuracy matters, an optional high-precision add-on enables true CO₂ measurements. This modular approach lets you start with meaningful air quality insight immediately and upgrade when needed.

Comfort, kept in balance.

Temperature & Humidity

Temperature and humidity are measured continuously to provide a clear picture of indoor comfort. These readings help identify conditions that feel too warm, too dry, or too humid often before you consciously notice them.

By understanding how temperature and humidity change throughout the day, automations can respond more intelligently, maintaining a stable and comfortable environment without constant manual adjustment.

Aware of light, indoors and out.

Light & UV Sensing

Integrated light and UV sensing measures ambient light levels (lux) and UV index, allowing the system to understand real-world lighting conditions in and around your home. This goes beyond simple on/off detection.

Lighting automations can respond naturally to daylight, cloud cover, and sun exposure enabling smarter behavior for lighting, shading, and energy efficiency based on actual conditions, not fixed schedules.

Clear signals, when you need them.

Physical Feedback

A built-in LED and buzzer provide immediate visual and audible feedback, offering clear confirmation when something changes. Whether it’s presence detection, air quality alerts, or system status, feedback is always direct and unambiguous.

Use Homey Flows or Home Assistant automations to control LED colour, brightness and sound. Link feedback to presence, air-quality readings or other events in your smart home.

Adapts to how and where you install it.

Modular by Design

Optional mounting add-ons enable flexible positioning. Choose a standard ball mount for flat wall surfaces, or a corner ball mount for clean installation in 90° wall corners.

Optional USB-C add-ons adapt the device to different installation scenarios. The device includes a standard USB-C port on the bottom for wall-mounted use with a cable. Use the male USB-C accessory for direct plug-in to a wall power adapter. Use the female USB-C accessory when placing the sensor upright on a shelf, TV cabinet, or other flat surface.

Every component chosen for accuracy, reliability and trust.
