Extend the reach of your Home Zone Living Secure MESH Linkable Lighting system with this wireless range extension sensor. When motion is detected, it instantly signals every linked light on the same channel from up to 327 ft (100 m) away, so one trigger lights your whole zone and eliminates blind spots. Set up to four lighting zones using simple onboard channel switches—no apps, Wi-Fi, or wiring required. The weather-resistant high-impact plastic housing stands up to year-round outdoor conditions, and battery power keeps it working through outages. Compatible with the entire Home Zone Living Secure MESH ecosystem, including security floodlights, garden pathway lights, and decorative wall lights (models ELI1576G, ELI1577G, ELI1621G, ELI1622G, ELI1655V, ELI1656V, ES00945G, ES00946G, ES00947G, ES00942G, ES00935G). Measures 3" x 1.7" x 3" (7.5 x 4.3 x 7.5 cm). Note: future Secure MESH products will also be compatible.
