Overview

The Shelly Wave i4 is a Z-Wave input controller designed to convert up to four physical switches or push-buttons into smart automation triggers. It does not switch loads directly and contains no relays; instead, it reports button actions to your Z-Wave network so they can trigger scenes, automations, or other devices.

Powered from 110–240 V AC and built on the Z-Wave 800 Series chipset, the device enables flexible control from standard wall switches while maintaining extremely low standby power consumption. As a mains-powered device, it can also act as a Z-Wave repeater to extend mesh network coverage.

Key features

  • Four digital inputs for switches or push-buttons
  • Input controller only with no relays or load switching
  • Supports short press, double press, and long press actions
  • Up to 12 actions or scenes configurable across four inputs
  • Supports Z-Wave associations for direct device control
  • Extremely low standby power consumption (< 0.2 W)
  • Z-Wave 800 Series (S800) chipset
  • SmartStart support for quick and secure inclusion
  • OTA firmware updates via compatible Z-Wave hubs
  • Security 2 (S2) authenticated encryption
  • Acts as a Z-Wave repeater to extend network coverage
