Key differences between Shelly Blu Motion and Shelly BLU Motion ZB

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

Specifications to check side by side
  • Zigbee (connectivity): Shelly Blu Motion — No; 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.).
  • Alexa (integrations): Shelly Blu Motion — Yes; 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.).
  • Google Home (integrations): Shelly Blu Motion — Yes; 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.).
  • Battery Type (power): Shelly Blu Motion — CR2477; Shelly BLU Motion ZB — 1x CR2477.
Information still to confirm
  • 5 of 25 comparison fields lack a resolved value for at least one selected device. Missing information is not evidence that a feature is absent.
  • Check the full table and manufacturer documentation before ruling out a device.

These observations are derived from recorded catalog data and have not all been independently verified. Confirm details with the manufacturer before purchasing.
