Aqara Motion Sensor P1 vs Ring Alarm Motion Detector comparison

Updated August 2026

Data from Amazon and official Aqara and Ring sites.

2026 verdict

The Aqara Motion Sensor P1 is the better overall motion sensor over the Ring Alarm Motion Detector, winning on price, integrations, sensor count and alerts. It is more affordable, adds a built-in light (lux) sensor plus low-battery alerts, and works broadly with Google, Alexa, HomeKit, Home Assistant and Matter, making it a flexible lighting-automation sensor for many ecosystems. The Ring Alarm Motion Detector holds a higher owner rating and is a genuinely pet-friendly security sensor (ignoring pets up to about 50 lbs) that pairs with the Ring Alarm system or third-party Z-Wave hubs like SmartThings, plus Alexa, Home Assistant and IFTTT. Both are indoor sensors that need a hub. Choose the Aqara Motion Sensor P1 for the cheaper, more versatile, light-aware sensor across more platforms; pick the Ring Alarm Motion Detector if you run Ring Alarm and want its top rating and pet-tolerant detection.
