Smart Zigbee Motion Sensor

This Third Reality sensor detects movement inside the home and triggers automations through any compatible Zigbee hub or Echo device that includes a built-in Zigbee radio. It is designed for homeowners who want simple presence-based routines without wiring or a separate bridge. Buyers who need outdoor-rated detection or a sensor that operates independently of a hub should look elsewhere.

Pet-Friendly Detection up to 9 Metres

The unit ignores animals while still sensing human motion at distances up to 9 metres, so everyday household pets will not cause false alerts. This single behaviour determines whether the device suits a home with cats or dogs. No sensitivity adjustment is mentioned in the specifications.

Battery-Powered Low-Energy Operation

Two included AAA 1.5 V cells power the sensor for roughly two years under typical use, and the Zigbee radio draws minimal current while idle. No mains connection or external power supply is required, keeping installation flexible and completely silent.
