The Shelly Wave Door/Window EU LR is a Z-Wave® S800-based contact sensor that detects open/closed status of doors and windows, as well as tilt angle (for tilt-turn windows) and ambient light levels. It supports both traditional Z-Wave mesh networks and Z-Wave Long Range mode (selectable during pairing), allowing optimized range and energy usage depending on your installation environment.
The sensor runs on a CR2032 coin battery with an estimated life of up to 2 years. It also supports OTA firmware updates, SmartStart pairing, and multiple Z-Wave security levels including S2. With its compact form factor and three available color options (white, black, brown), it offers discreet and flexible installation.
Typical use cases include optimizing heating and cooling by detecting window openings, intrusion detection and alerts, and triggering lighting scenes based on contact status and light levels.
Z-Wave is a wireless RF communication protocol specifically designed for home and small business automation, monitoring, and control. It is a mature and widely adopted technology that connects millions of affordable, reliable, and easy-to-use smart devices worldwide.
Interoperability is a core principle of Z-Wave: all certified Z-Wave devices work together regardless of brand. Mains-powered devices in the network act as repeaters, improving network reliability. The Z-Wave ecosystem includes over 4,000 certified products, with strong backward and forward compatibility, and more than 100 million Z-Wave devices are in use globally.
