Apollo MSR-2 mmWave Multisensor| LD2410B

The ultimate mmWave multisensor for your smart home

The Apollo MSR-2 is a dream for every Home Assistant user. This compact and powerful multi-sensor comes standard with advanced technology to make your home automation smarter, faster, and more reliable. Thanks to the LD2410B mmWave sensor, it accurately detects presence, while other built-in sensors give you a complete picture of your surroundings.

But the MSR-2 is more than just a presence sensor. It's designed to grow with you. Want to accurately measure air quality? No problem. The sensor is ready for a simple, self-service upgrade.

Complete it with an optional CO2 sensor

Gain complete control over your indoor climate by expanding the MSR-2 with the optional CO2 sensor . This add-on module can be easily installed on the board yourself. Once installed, it measures the CO2 concentration in the air. This is ideal for automatically controlling your ventilation system and ensuring a healthy and productive living environment, without you having to think about it.

Core functions of the MSR-2

• Accurate presence detection : The LD2410B mmWave sensor detects not only motion but also people sitting still up to 6 meters away. Perfect for spaces where you're quietly reading or working; the lights stay on as long as you're there.
• Packed with sensors : As standard, the MSR-2 measures temperature and air pressure (DPS310 sensor) and light intensity (LUX) and UV index (LTR390 sensor).
• Built for Home Assistant and Homey : Seamless and fully local integration via ESPHome. No cloud, no subscriptions, maximum privacy.
• Customizable Feedback : A built-in RGB LED and a piezo buzzer give you visual or audible notifications for any situation you can imagine.
• Easy installation : Plug and play via a USB-C connection. Connect to the hotspot, enter your Wi-Fi details, and Home Assistant will discover it automatically.

Practical application: the smartest office automation

Install the MSR-2 (with the optional, self-installable CO2 sensor ) in your home office:

As soon as you enter, the mmWave sensor detects your presence and turns on the lights (if the LUX sensor detects darkness). While you're working, the lights stay on, even if you're sitting still. If the CO2 level rises too high, the RGB LED glows red, and the mechanical ventilation automatically increases. This way, you always stay alert and comfortable.
