What the differences mean

Purpose and hub

The Aqara Motion Sensor P1 is a Zigbee sensor for automations on an Aqara hub or any Zigbee hub. The Ring Alarm Motion Detector is a Z-Wave security sensor for a Ring Alarm base station or another Z-Wave hub.

Platforms

The Aqara works with SmartThings and Home Assistant directly, and with Alexa, Google Home, Apple Home and Matter through an Aqara hub. The Ring works with Alexa and Home Assistant.

Coverage

170 degrees on the Aqara against 90 on the Ring, with rated ranges of 7 m and 7.6 m. Aqara owners report a much shorter real range, so the wide angle is its real advantage.

Light sensing

The Aqara has a light sensor accurate enough to switch lights only after dark. The Ring's light sensing is not documented.

Size and batteries

The Aqara is a 30 g, 33 mm cube rated for five years on two CR2450 cells. The Ring is larger at 66 x 66 x 38 mm and runs on two AA batteries.

What owners say

Owners of both sensors describe quick pairing and detection that responds fast when someone walks past. Aqara Motion Sensor P1 owners like how tiny it is, the accurate light sensor, the configurable timeout and pairing straight to Home Assistant without an Aqara hub, but they find the real range much shorter than rated, see slow movement slip past it, note that its timer does not reset while someone stays in the room and dislike having to pry it open to change batteries. Ring Alarm Motion Detector owners single out pet tolerance, with dogs of 40 to 50 lb ignored when mounted at 7 to 8 ft, and years between battery changes, while they mention a Ring Protect subscription for full event history and adhesive that does not always hold.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
