Smart dimmer with Matter support

The KS225 is a single-pole smart dimmer switch that requires a neutral wire and connects over 2.4GHz Wi-Fi. It integrates with Apple Home, Alexa, Google Home and SmartThings through the Matter standard, allowing local LAN control even when the internet is down. Multi-Admin lets several platforms manage the same device at once.

Sustained operation on local network

Because the switch uses LAN-based Matter communication, it continues to respond to schedules, timers and voice commands without cloud latency during extended daily use. The 1% to 100% dimming range adjusts smoothly whether triggered by the app, a voice assistant or the physical toggle, and Away Mode cycles lights automatically while you are away.

Neutral-wire requirement decides fit

Installation is only possible in switch boxes that already provide a neutral conductor; homes without that wiring cannot use this model. The KS225 carries UL certification and supports 2.4GHz Wi-Fi exclusively, so it will not join 5GHz networks.

Questions about this item

How much heat does the KS225 dimmer generate when it runs continuously at 100% brightness?

The KS225 is a smart dimmer switch, not a USB cable, so it produces minimal heat during normal dimming operation and is UL certified for safe continuous use.

What existing wiring must my home have for the KS225 to function?

The KS225 requires a neutral wire in the switch box and a single-pole lighting circuit, plus a 2.4GHz Wi-Fi network for Matter pairing.

Will the KS225 work with my older non-smart LED bulbs that lack Matter support?

Yes, the KS225 dims standard dimmable LED, incandescent, and halogen bulbs from 1% to 100% without requiring smart bulbs.
