For a hall or landing light that should come on the moment you step in, the Shelly Blu Motion is the better of these two indoor motion sensors.

It covers a wider 120 degrees, runs up to about five years on a single CR2477 cell and carries a two-year warranty, where the SwitchBot Motion Sensor sees 110 degrees horizontally and 55 vertically and lasts about three years on 2x AAA with a one-year warranty. The SwitchBot Motion Sensor is the cheaper of the pair and reaches Apple Home and Matter through a SwitchBot Hub, a path the Shelly Blu Motion does not offer at all. Both need a bridge and both add a built-in lux sensor. Pick the Shelly Blu Motion for long life and wide coverage inside a Shelly setup, and the SwitchBot Motion Sensor for the lower price or an Apple Home and Matter household.

What the differences mean

Battery

The Shelly Blu Motion runs up to about five years on a single CR2477 cell, while the SwitchBot Motion Sensor is rated for about three years on 2x AAA. Over the life of the sensor that is fewer battery changes on the Shelly.

Detection angle

The Shelly Blu Motion covers a 120 degree field, against 110 degrees horizontal and 55 degrees vertical on the SwitchBot Motion Sensor. The Shelly sees a wider slice of a room, so it needs less careful aiming to avoid a blind spot.

Which bridge it needs

The Shelly Blu Motion is relayed by any Shelly Plus, Pro or Gen3 device or a Shelly BLU Gateway, so it is cheap to add inside a Shelly home. The SwitchBot Motion Sensor needs a SwitchBot Hub, which is also what unlocks Alexa, Google Home, IFTTT and Matter for it.

Apple Home and Matter

Through its Hub the SwitchBot Motion Sensor reaches Apple Home and Matter. The Shelly Blu Motion supports neither HomeKit nor Matter, so an Apple-first household gains nothing from it.

Warranty

The Shelly Blu Motion is covered for two years and the SwitchBot Motion Sensor for one, the longer protection going to the battery-first sensor.

What owners say

Owners of both sensors start from the same place: each is a small, Bluetooth-only indoor unit with a built-in lux sensor that needs a bridge before it can do anything. Shelly Blu Motion owners single out how fast it responds, how tiny and discreet it is, and how easy setup is, since it ships powered on and Home Assistant auto-detects it over BTHome when another Shelly bridges it; up to five years on its cell and the value are repeated, while the complaints are that it needs that Shelly bridge, falls apart outdoors with limited range, and comes with sparse instructions. SwitchBot Motion Sensor owners praise the reset-on-motion timer that keeps lights on while they are in the room and the easy magnetic mounting, and they flag a activation delay of a few seconds and that it cannot trigger Google Home routines.
