E1 Pro Multi Sense

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

Dedicated wall and ceiling modes ensure accurate detection for different mounting positions. Combined with 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 and stable.

For environments where air quality directly impacts health, comfort, and productivity, an optional high-precision SCD40 add-on enables true CO₂ measurements. This modular approach lets you add CO₂ monitoring only when needed, while the base system remains focused and efficient, ideal for smart ventilation, occupancy-based automation, and data-driven indoor air quality decisions.

As an alternative, the optional BME688 air quality add-on provides a broader environmental overview with eCO₂ estimation, VOC, IAQ, temperature, humidity, pressure, and gas resistance measurements for extended indoor air quality monitoring. Only one air quality add-on can be installed, allowing you to choose between precision CO₂ sensing (SCD40) or multi-parameter air quality insight (BME688).

Air pressure is measured by default and supports automatic compensation when the optional SCD40 add-on is installed, helping maintain consistent CO₂ accuracy across changing weather and altitude conditions.

When either the SCD40 or BME688 add-on is installed, temperature and humidity are monitored continuously to provide a clear, real-time view of indoor comfort, helping identify conditions that feel too warm, too dry, or too humid, often before you consciously notice them.

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.

4 front facing LEDs and a built-in buzzer provide immediate visual and audible feedback, offering clear confirmation when something changes. Whether it’s presence detection, alerts, or system status, feedback is always direct and unambiguous.

All feedback behavior is fully controlled through Home Assistant automations, giving you complete control over when, how, and if the device communicates from subtle indicators to clear alerts.

An optional CO₂ sensor add-on extends the device with direct carbon dioxide measurements, making it suitable for environments where air quality plays an important role.

Built-in wall and ceiling mounting options are available for a clean, flush installation. You can choose to purchase the mount or print it yourself free of charge and customize it to your needs using the provided design files.

Data is delivered primarily over Ethernet, providing a stable and reliable base connection. Power can be supplied via PoE or USB-C, allowing the device to adapt easily to different installation scenarios.

Wi-Fi connectivity is also supported and can be enabled through a simple firmware update, making it possible to switch between Ethernet-based and Wi-Fi-based setups when needed.

Optional Bluetooth proxy support allows the device to act as a bridge for nearby BLE devices, supporting presence systems such as Bermuda and ESPresence.
