Wave i4
Z-Wave scene controller with four digital inputs (SW1-SW4) that reads pulses from physical switches or buttons to trigger scenes, synchronized actions, and automations across your Z-Wave network. Mains-powered and fits behind any wall switch.
Local over Z-Wave (Z-Wave JS), no cloud. Four dry-contact inputs trigger up to 12 scenes or actions; available in AC (110-240V) and DC (5-24V) mains-powered variants with Z-Wave Plus / Z-Wave 800 Long Range and S2 (AES128) security; the mains-powered AC device repeats the Z-Wave mesh in standard (non-Long Range) mode.
