What the differences mean

Battery life

The Sonoff SNZB-03P ZigBee Motion Sensor lists 3 years on a CR2477 cell and the Sonoff SNZB-03 ZigBee Motion Sensor 1 year on a CR2450. Over several sensors, that is a lot fewer battery swaps.

Size

The Sonoff SNZB-03 ZigBee Motion Sensor is 40 x 35 x 28 mm and 21 g, and the Sonoff SNZB-03P ZigBee Motion Sensor is 44 x 44 x 65 mm and 54 g. The older one is the one to hide behind a decoration or in a mailbox.

Light sensor and timeout

The Sonoff SNZB-03P ZigBee Motion Sensor adds a basic light sensor for dark-only automations and a detection timeout you can set. The Sonoff SNZB-03 ZigBee Motion Sensor has neither, so it reacts to motion whatever the light and cannot be tuned.

Google Home

Google Home is listed for the Sonoff SNZB-03P ZigBee Motion Sensor and not for the Sonoff SNZB-03 ZigBee Motion Sensor. Both work with Alexa, SmartThings and Home Assistant.

Detection

Angle (110 degrees) and range (6 m) are the same on both, so coverage is not what separates them. Neither offers adjustable motion sensitivity.

What owners say

Owners of both Sonoff sensors buy them as cheap, easy-to-pair Zigbee motion sensors that work with many hubs beyond Sonoff's own, including Home Assistant, SmartThings and Hubitat. Sonoff SNZB-03 ZigBee Motion Sensor owners like how tiny and discreet it is, even enough to use in a mailbox, but the most repeated complaint is that it drops off the hub and needs re-pairing about once a month, with a fixed interval of roughly a minute before it detects motion again and some units failing within months. Sonoff SNZB-03P ZigBee Motion Sensor owners single out near-instant detection, flexible mounting with a magnetic base and a long battery life, and they mention a light sensor that only reports dim or bright, a motion entity that can stick in Home Assistant and the occasional dropped connection.

Upgrading from the Sonoff SNZB-03 ZigBee Motion Sensor?

Moving up from the Sonoff SNZB-03 ZigBee Motion Sensor to the Sonoff SNZB-03P ZigBee Motion Sensor buys a longer battery life (3 years against 1), Google Home support, a basic light sensor and a detection timeout you can set. Detection angle and range stay the same, and both still need a Zigbee hub. Owners of the older one who fight with dropped connections have the most to gain, while an older sensor tucked away in a tiny spot is fine to keep. The newer body is bigger, so check that it fits.

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.
