Key differences between Aqara Presence Sensor FP2 and Shelly Presence Gen4
A summary of selected recorded differences between these presence sensors. Check the full specification table below for details and conditions.
Feature differences among your selected devices
- Fall Alerts (alerts): Aqara Presence Sensor FP2 — Yes (The FP2 has the capability to detect and alert you when a family member falls down.); Shelly Presence Gen4 — No.
- Sleep Monitoring (features): Aqara Presence Sensor FP2 — Yes (The FP2 offers independent sleep monitoring capabilities without the need for wearables. It provides real-time tracking of heart and respiratory rates, along with historical reports for deeper insights into sleep quality. Additionally, Aqara Home automation features enable convenient actions such as automatically turning off lights when going to bed or activating night lights upon getting out of bed at night.); Shelly Presence Gen4 — No.
- Matter (integrations): Aqara Presence Sensor FP2 — No; Shelly Presence Gen4 — Yes (Matter over Wi-Fi. CSA certificate CSA25E3FMAT48529-24, certified 2025-11-18, vendor 0x1490 product 0x1821.).
Specifications to check side by side
- Zigbee (connectivity): Aqara Presence Sensor FP2 — No; Shelly Presence Gen4 — Zigbee Hub required (Zigbee 3.0 (802.15.4). A five-press on the button switches the firmware between Matter over Wi-Fi (the default) and Zigbee. Using the Zigbee radio needs a Zigbee coordinator.).
- Angle Of Detection (features): Aqara Presence Sensor FP2 — 120°; Shelly Presence Gen4 — 140° Horizontal / 120° Vertical.
- Area Of Detection (features): Aqara Presence Sensor FP2 — 40 m² (By using only one radar sensor, you will be able to monitor a room of up to 40 m² (ca. 430 sq ft) and divide them into various zones.); Shelly Presence Gen4 — 42 m².
- Range Of Detection (features): Aqara Presence Sensor FP2 — 7m / 23ft; Shelly Presence Gen4 — 8m / 26ft.
