2026 verdict

The Sonoff SNZB-03P ZigBee Motion Sensor is the more capable motion sensor overall against the Ring Alarm Motion Detector, taking the win on price, integrations and its wider sensor set. Beyond motion it adds a built-in light sensor, low-battery alerts and history logging, pairs with almost any Zigbee hub (SmartThings, Hubitat, Home Assistant), and works with Alexa and Google Home for fast, near-instant lighting automations at a low price. The Ring Alarm Motion Detector counters with a genuine strength: it carries a higher owner rating and is a truly pet-friendly security sensor (up to about 50 lbs) that fits the Ring Alarm system or a Z-Wave hub.
