Shelly Wave i4 DC ZWave LR 800 4 Input Module

The Shelly Wave i4 DC is a compact Z-Wave smart input module designed to give you flexible, reliable control over your smart home automation system. It allows you to connect up to four physical switches or push-buttons and use them to trigger scenes, automations, or control other Z-Wave devices within your network.

Unlike relay-based devices, the Wave i4 DC is a dedicated input controller, meaning it does not switch electrical loads directly. Instead, it acts as a smart trigger for your connected Z-Wave ecosystem.
