Smart Shield Systems
IQ Dimmer
Set the perfect mood—and save energy—by dimming lights from your IQ Panel and phone. The IQ Dimmer comes in two styles: a plug-in Z-Wave module for lamps and an in-wall PowerG dimmer switch for hard-wired fixtures. We’ll help you choose the right version and install it cleanly so your lighting just works.

Frequently Asked Questions
Which version should I get—plug-in or in-wall?
Choose plug-in Z-Wave for lamps you plug into an outlet. Choose the in-wall PowerG switch for hard-wired light fixtures you want on a wall dimmer. We can mix both under the same IQ system.
Will it work with LED bulbs?
Yes—use dimmable LED/CFL bulbs within the wattage limits (Z-Wave plug-in: 65W dimmable CFL/LED; PowerG in-wall: 100W CFL/LED total).
How far will it reach?
The plug-in Z-Wave dimmer reaches about 130 ft LOS and also helps extend your Z-Wave mesh; PowerG in-wall is designed for very long range in typical homes and small businesses.
Is this okay for outdoor or damp areas?
No—both versions are indoor-only devices. Ask us about outdoor-rated options if needed.
Do I need an electrician?
For the in-wall PowerG switch, professional installation is recommended to ensure proper line/load wiring and code compliance. (Our team handles this for you.)
