The Shelly Wave Pro 2 is a professional DIN-rail Z-Wave smart relay with two independent channels, designed for installation inside electrical cabinets and consumer units. Each channel supports switching up to 16 A, with a 25 A total device limit, making it suitable for lighting circuits, appliances, and automation systems in residential or commercial environments.

Featuring potential-free (dry contact) outputs, the device can switch both low- and high-voltage circuits independently of the supply voltage. Built on the Z-Wave 800 Series platform, it provides secure communication, SmartStart inclusion, and reliable control through compatible Z-Wave gateways and home automation systems such as Home Assistant.
