The Shelly Wave i4 DC is a Z-Wave input controller designed to convert up to four physical switch inputs into smart automation triggers. Instead of switching loads directly, it reports button presses and input events to your Z-Wave smart home system, allowing switches or buttons to control other devices, scenes, or automations.

Powered by low-voltage DC (5–24 V) and built on the Z-Wave 800 Series chipset, the module provides reliable communication while maintaining extremely low power consumption. It supports multiple press actions per input, making it suitable for advanced automation control panels or multi-function wall switches.

Key Features
  • Four digital inputs for switch or push-button connections
  • Input controller only with no relays or load switching
  • Supports short press, double press, and long press actions
  • Up to 12 actions or scenes across four inputs
  • Supports Z-Wave associations for direct device control
  • Extremely low power consumption (< 0.3 W)
  • Z-Wave 800 Series (S800) chipset
  • SmartStart support for quick device inclusion
  • OTA firmware updates via compatible Z-Wave hubs
  • Security 2 (S2) authenticated encryption
