Shelly Wave Pro 2 – 2-Channel Z-Wave DIN-Rail Smart Relay (Dry Contacts)
Overview
Shelly Wave Pro 2 is a professional-grade 2-channel Z-Wave smart relay designed for DIN-rail installation inside electrical cabinets and consumer units. Each channel supports up to 16A, with a combined device maximum of 25A, making it suitable for controlling lighting circuits, appliances, and automation loads in both residential and commercial environments.
The device features potential-free (dry contact) outputs, allowing it to switch a wide range of voltages and circuits independently of the supply voltage. Control, automation, and scheduling are handled via a compatible Z-Wave gateway and supported home automation platforms such as Home Assistant.
