Smart home

Works with the home app you already use

zPLC is a Matter device. Add it once to Apple Home, Alexa, Google Home or SmartThings, and every light on its circuit dims and changes color temperature from your phone, your voice or a schedule. No separate hub and no extra apps.

What it controls

Your lights, your switch

What you can do depends on the lights on the circuit and the switch you choose.

Troubleshooting

A bulb does not respond at allConfirm it is on the same circuit as the zPLC switch.
