Key differences between Shelly BLU Motion ZB and SwitchBot 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

Detection Timeout (features): Shelly BLU Motion ZB — Yes (Motion hold time is configurable in seconds (60 by default): while movement continues the timer restarts, and a motion clear event is emitted once it expires.); SwitchBot Motion Sensor — No.

Specifications to check side by side

Motion Alerts (alerts): Shelly BLU Motion ZB — Yes (Every motion detection is broadcast as an event over BTHome and sent over Zigbee to the bound devices, and the app can push a notification when movement is detected.); SwitchBot Motion Sensor — SwitchBot Hub required.
Zigbee (connectivity): Shelly BLU Motion ZB — Zigbee Hub required (Zigbee 3.0 end device (IAS Zone 0x000D, profile 0x104, 802.15.4), so it joins an existing Zigbee coordinator.); SwitchBot Motion Sensor — No.
Automations (features): Shelly BLU Motion ZB — Yes (Motion and light-level events trigger scenes and automations from the Shelly Smart Control app, and scripting is available through a gateway.); SwitchBot Motion Sensor — SwitchBot Hub required.
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.); SwitchBot Motion Sensor — SwitchBot Hub required.
