The FP2's radar technology operates continuously, mapping room occupancy without the blind spots typical of traditional PIR systems. It detects micro-movements and breathing patterns, ensuring reliable presence detection regardless of user activity levels.
Wireless Protocol Integration
- MultiSensor 7: Z-Wave Plus mesh networking with gateway requirement
- FP2: Wi-Fi connectivity with direct HomeKit, Alexa, and Google integration
- Hub dependency: Z-Wave controller needed vs hub-free operation
Power requirements differ significantly, with the MultiSensor 7 offering flexible battery or mains operation, whilst the FP2 requires constant mains power for its radar system. This impacts installation flexibility and ongoing maintenance considerations for different home environments.
Real-World Accuracy and Response Times in Home Environments
In practical testing across various room types, both sensors demonstrate distinct performance characteristics that suit different automation needs. The MultiSensor 7 excels in comprehensive room monitoring, with its motion sensor providing reliable PIR-based detection for general occupancy awareness, whilst environmental sensors deliver continuous data for climate and lighting automation.

Aeotec MultiSensor 7 Strengths and Limitations
The MultiSensor 7's greatest strength lies in its versatility as an all-in-one environmental monitoring solution. Its six-sensor array eliminates the need for multiple devices, providing comprehensive room data through a single Z-Wave node. This occupancy sensor integrates seamlessly into Z-Wave mesh networks, extending network range whilst reducing device count.
Key Advantages
- Comprehensive environmental data from a single device
- Flexible power options supporting both battery and mains operation
- Z-Wave mesh networking extends system coverage
- Tamper detection through integrated vibration sensing
However, the device's complexity can present challenges. Battery life varies significantly based on reporting frequency and sensor usage, with environmental sensors consuming more power than basic motion detection. The automatic sensor's multiple functions may overwhelm users seeking simple occupancy detection, and Z-Wave gateway dependency adds infrastructure requirements for new smart home adopters.
Aqara FP2 Benefits and Trade-offs
The FP2's specialised focus on presence detection delivers unmatched accuracy for occupancy-based automation.
