Shelly Wave i4
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.
