Key differences between Shelly BLU Motion ZB and Sonoff SNZB-03P ZigBee Motion Sensor

A summary of selected recorded differences between these motion sensors. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Bluetooth (connectivity): Shelly BLU Motion ZB — Yes (Bluetooth 5 (LE) broadcasting in the BTHome format, running simultaneously with Zigbee. Remote control needs a Shelly BLU Gateway or a Shelly Plus, Pro, Gen3 or Gen4 device as the bridge.); Sonoff SNZB-03P ZigBee Motion Sensor — No.
Motion Sensitivity (features): Shelly BLU Motion ZB — Yes (Three PIR sensitivity levels (low, medium, high), adjustable to cut false triggers from pets or distant movement.); Sonoff SNZB-03P ZigBee Motion Sensor — No.

Specifications to check side by side

Alexa (integrations): Shelly BLU Motion ZB — Shelly gateway required (Reaches Amazon Alexa through the Shelly Smart Control account, and the product page states that a compatible Bluetooth or Zigbee gateway is required for automations and app control.); Sonoff SNZB-03P ZigBee Motion Sensor — Yes.
Apple Home (integrations): Shelly BLU Motion ZB — No (The device documentation lists only Bluetooth 5 LE and Zigbee 3.0, with no Matter or HomeKit profile, and Shelly's compatibility page names only Alexa, Google Home and SmartThings.); Sonoff SNZB-03P ZigBee Motion Sensor — SONOFF Hub required (SONOFF lists this model among the Zigbee devices its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) publish to Matter, which is how it reaches the Apple Home app. Apple Home has no Zigbee radio of its own.).
Google Home (integrations): Shelly BLU Motion ZB — Shelly gateway required (Reaches Google Home through the Shelly Smart Control account, and the product page states that a compatible Bluetooth or Zigbee gateway is required for automations and app control.); Sonoff SNZB-03P ZigBee Motion Sensor — Yes.
