FAST AND RELIABLE: Get notified on your Z-Wave hub's app or via text when a door or window is opened for easy DIY security monitoring. Use on safety gates, cabinet doors, patio doors, and more. Z-Wave hub required, sold separately (check below for compatibility). | EXTRA SMALL: Perfect for discreet mounting with a slim profile to fit most frames and surfaces. | OUTDOOR CASE AVAILABLE: The sensor is coated with protective rubber oil against corrosion and water leak damage. A splash is fine but if you want to install it outdoors, you'll need a dedicated waterproof case (sold separately, ask Zooz about it). | Z-WAVE COMPATIBILITY: Works best with the Z-Box Hub. Supported by open Z-Wave systems only, including Home Assistant, HomeSeer, Hubitat, Vera, and Ezlo hubs. Compatible with SmartThings and Ring Alarm (no access to advanced settings). NOT supported by alarm panels like Vivint, Qolsys, 2GIG, ADT, or others. | SMART SECURITY: 800 series Z-Wave chip with longer range, better battery life, and the highest level of S2 security with SmartStart for fully encrypted communication. If your hub supports ZWLR, you'll benefit from ultra reliable wireless communication and up to 1300 feet of range. Covered by a 5-year extended warranty once registered and backed by lifetime tech support 7 days a week.
