The Shelly Blu Motion undercuts the YoLink Indoor Motion Sensor RT on price and adds a built-in lux sensor and Bluetooth, though it depends entirely on another Shelly device or a BLU Gateway to reach the rest of a smart home. The YoLink Indoor Motion Sensor RT counters with the higher owner rating and radar sensing instead of Bluetooth-only detection, plus a wider integrations list once its Local Hub is added, reaching Apple Home, Google Home, SmartThings and Matter that the Shelly never touches. Each adds a different extra sense, Shelly a lux reading, YoLink a temperature one. Choose the Shelly Blu Motion if you already run Shelly hardware and want the lowest price; choose the YoLink Indoor Motion Sensor RT for the widest platform reach and radar detection.

What the differences mean

Getting to a smart home

The Shelly Blu Motion is Bluetooth-only and needs another Shelly device or a BLU Gateway to bridge it to Wi-Fi. The YoLink Indoor Motion Sensor RT needs its own YoLink hub over LoRa, and specifically the YoLink Local Hub to reach Apple Home, Google Home, SmartThings and Matter.

Sensing method

The YoLink Indoor Motion Sensor RT detects with microwave radar, which reacts to movement itself. The Shelly Blu Motion's detection is Bluetooth-linked motion sensing rather than radar.

Extra sensor

The Shelly Blu Motion adds a lux (light) sensor for dark-only triggers. The YoLink Indoor Motion Sensor RT adds an auxiliary temperature reading instead.

Battery

The Shelly Blu Motion is rated up to five years on a CR2477. The YoLink Indoor Motion Sensor RT is rated two years on AA batteries.

Price

The Shelly Blu Motion is the cheaper of the two, though it also reaches fewer smart home platforms out of the box without adding a Shelly bridge device or a BLU Gateway.

What owners say

Owners of the Shelly Blu Motion consistently praise how fast it reacts, often within a second, and how discreet it is once mounted, small enough to disappear against a wall. It ships already powered on, and Home Assistant users say it is auto-detected the moment it is nearby, provided a Shelly device is already acting as the Bluetooth-to-Wi-Fi bridge. They value the sensitivity levels with pet filtering and the lux sensor for dark-only triggers, and battery life up to five years gets repeat mentions. Their main complaint is architecture: without another Shelly device or a BLU Gateway it cannot reach the rest of the smart home at all, and a few say Shelly's instructions are too sparse to configure it the way they wanted on the first try.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
