R PRO-1 PoE mmWave Multisensor

The Apollo Automation R PRO-1 PoE mmWave Multisensor is our most advanced presence sensor. Designed for power, precision, and reliability, the R PRO-1 is a compact PoE mmWave sensor built for high-accuracy motion detection and environmental monitoring in smart homes and commercial buildings.

This versatile sensor supports true PoE (802.3 compliant) and USB-C power, and includes built-in Wi-Fi and Bluetooth connectivity, enabling flexible installation and seamless smart home integration. Its small form factor combined with PoE or USB-C power options makes the R PRO-1 ideal for quick deployments in a wall or ceiling.

Equipped with optional support for the SCD40 (true NDIR CO₂), the R PRO-1 transforms into a powerful all-in-one indoor environmental monitor.

The device proudly carries the Made for ESPHome badge, ensuring full compatibility and easy integration with the ESPHome ecosystem and Home Assistant. It will ship with a Wi-Fi firmware that can easily be changed to PoE in the device dashboard.

The base sensor includes the LD2450, which provides true multi-zone motion tracking with defined zones in its field of view. The optional LD2412 which works in addition to the LD2450 excels in still presence detection, allowing accurate sensing of seated or resting individuals. Together, these two mmWave sensors work in tandem to deliver comprehensive, real-time occupancy data.

Like all Apollo products, the R PRO-1 is fully local, open-source, and requires no cloud subscription. It is a top-tier choice for anyone seeking a privacy-focused, local-first motion and environmental sensor.

DetailsDual mmWave Compatibility: LD2412 and LD2450

• The R PRO-1 supports both the LD2412 and LD2450 mmWave radar modules:
• LD2412 (Optional) delivers high-accuracy still presence detection, ideal for seated or sleeping individuals.
• LD2450 enables multi-zone motion tracking, allowing you to identify precise movement and location across zones.You can combine both modules to create a hybrid smart presence sensor capable of advanced occupancy detection in real time.

Smart Environmental Sensing Features

• In addition to presence tracking, the R PRO-1 also functions as a robust environmental monitoring sensor, including:
• LTR390 for ambient lux and UV sensing
• Two addressable RGB LEDs for visual notifications and automation feedback
• Piezo buzzer for audio alerts
• Bluetooth support for tracking and Improv Wi-Fi provisioning

Optional Mezzanine Expansion Board:

• SCD40 for high-accuracy NDIR CO₂ sensing.
• Together, these components make the R Pro-1 a feature-rich air quality and environmental sensor suitable for automation, air monitoring, and energy-efficient control.

Modular and Customizable

• Rear mezzanine port for modular add-ons

Compact, Flexible Installation

• With a size of approximately 57x45mm, the R PRO-1 is designed for easy and versatile installation:
• Mount on a flat surface
• Fit into a standard single gang box
• Ceiling mount as needed for discreet motion and presence detection

As with many sensors, heat can affect the optional temperature and humidity readings, requiring significant calibration offsets. CO₂ measurements may be skewed when the sensor is recessed in walls or ceilings. Although we originally did not plan to include these additional sensors due to such challenges, feedback from the Home Assistant and smart home communities encouraged us to offer these options for users who want enhanced environmental monitoring.
