Shelly Wave 1

Overview

Shelly Wave 1 is a compact, single-channel Z-Wave smart switch with a voltage-free (dry contact) relay, designed for flexible control of a wide range of electrical devices. It is suitable for switching lighting circuits, electrical locks, gates, garage doors, irrigation systems, LED strips, sockets, and other low- or high-voltage loads up to 16A.

Thanks to its dry contact output, Shelly Wave 1 can be used in applications where the switching circuit must remain electrically isolated from the device’s own power supply. It supports both AC and DC power input, making it highly adaptable for residential, commercial, and automation-focused installations.

Built on the latest Z-Wave 800 Series platform, the device supports SmartStart inclusion, S2 Authenticated security, OTA firmware updates, and Z-Wave mesh networking for reliable and secure operation.
