Key differences between Heiman WiFi Smart Motion Sensor 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.

Feature differences among your selected devices

2.4 GHz Wi-Fi (connectivity): Heiman WiFi Smart Motion Sensor — Yes; Shelly BLU Motion ZB — No.
Bluetooth (connectivity): Heiman WiFi Smart Motion Sensor — No; 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.).
Light (sensors): Heiman WiFi Smart Motion Sensor — No; Shelly BLU Motion ZB — Yes (Built-in lux sensor reporting three levels (dark, twilight, bright) with configurable thresholds, 50 lx dark and 500 lx bright by default.).

Specifications to check side by side

Zigbee (connectivity): Heiman WiFi Smart Motion Sensor — 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): Heiman WiFi Smart Motion Sensor — 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.).
SmartThings (integrations): Heiman WiFi Smart Motion Sensor — No; Shelly BLU Motion ZB — Shelly gateway required (Reaches SmartThings 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 Life (power): Heiman WiFi Smart Motion Sensor — 2 years; Shelly BLU Motion ZB — 5 years.
