not compatible with the Philips Hue protocol.

Matt Martin
Lackluster performer

This motion sensor reports 6% an a new battery & suffers from low range / dropouts. Nice compact size makes it barely noticeable. Decided to place it in the same room as the zigbee antenna where it is performing reasonably well.

Dario Saracino
It's all good

Just one at moment to try. But easy to connect and set-up.

Jarom West
Works great.

Works great, paired up correctly right out of the box. The sensor detection motion range appears to be pretty wide, and the device's responsiveness is fairly instantaneous. Overall for the price, great value for a sensor.

Motion Sensor works great

Motion sensor is super easy to add to the network
