About the NCLTG Smart Dimmer Switch (Matter)
The NCLTG Smart Dimmer Switch is a 400W in-wall dimmer for dimmable LED lighting that connects over Wi-Fi with Matter. It installs in a standard single-gang box without a neutral wire, which makes it a practical fit for older buildings and retrofit projects where no neutral is run to the switch box. No hub is needed: connect the switch to a 2.4 GHz Wi-Fi network and control it from a Matter-compatible smart home app, or right at the wall.
Four buttons on the faceplate (On/Off, Brighten, Dim and Mode) give hands-on control, and three preset scenes (Night Light, Work and Leisure) are built in. Schedules and remote control are set up in the app. The dimmer runs from 1% to 100% with a 3W minimum load, on TRIAC-dimmable LED loads at 120–277V. Works with any compatible dimmable LED lighting, not only NCLTG fixtures.
Need a bigger load? The NCLTG PLC Smart Switch is available in 600W (F361WTD1) and 800W (F381WTD1) versions for larger circuits and NCLTG PLC-enabled lighting. Contact sales@ncltg.com or call (704) 910-2876 for availability.

Smart Dimmer Switch FAQ
Does it need a neutral wire?
No. The Smart Dimmer is a single-pole switch that installs without a neutral wire, so it fits standard single-gang boxes where no neutral is run to the switch.
Do I need a hub?
No dedicated hub is required. The switch connects to a 2.4 GHz Wi-Fi network and is set up with a Matter-compatible smart home app. Some smart home platforms use a home controller, such as a smart speaker, for remote access and automations.
What lighting does it work with?
TRIAC-dimmable LED lighting on 120–277V circuits, from a 3W minimum up to a 400W maximum load. It works with compatible dimmable LED fixtures and lamps from any brand, not only NCLTG.
Can it be used for 3-way or multi-location switching?
No. The Smart Dimmer is designed for single-pole circuits controlled from one location.
What are the buttons and scenes for?
The faceplate has On/Off, Brighten, Dim and Mode buttons. Three preset scenes are built in: Night Light, Work and Leisure.
What if I need more than 400W?
The NCLTG PLC Smart Switch comes in 600W and 800W versions for larger circuits and NCLTG PLC-enabled lighting. Contact our team to talk through which fits your project.
Who should install it?
Installation by a qualified electrician is recommended. Always turn off power at the breaker before wiring and follow local electrical codes.
