Outdoor Smart Dimmer Plug

The TP-LINK KP405 is a weather-resistant smart dimmer designed for outdoor dimmable lighting such as string lights or landscape fixtures. It connects directly to a 2.4 GHz Wi-Fi network without a separate hub and responds to voice commands through Alexa or Google Assistant.

Dimming Capacity and Power Limits

The unit handles up to 4 Amps with a maximum load of 300 W for incandescent bulbs or 150 W for LED and CFL lamps. It is built exclusively for dimmable lights; non-dimmable loads cannot use the dimming function and may exceed the rated capacity.

Wi-Fi Range and Environmental Rating

The plug offers a wireless reach of up to 300 ft in open areas thanks to an integrated power amplifier. Its IP64 rating protects against dust ingress and water splashes, while the UL94-V0 enclosure adds fire and heat resistance for outdoor durability.

Will this KP405 dimmer work with the incandescent string lights I already have on my patio?

How can I verify the KP405 is operating correctly once installed outdoors?

In the Kasa app you will see the device online, can adjust the brightness slider and the connected lights will change level, and you can test a scheduled on/off event.

What comes in the box and is any extra hardware needed for mounting?

The package includes the plug-in dimmer with a 6-inch cable, a clamp and screw for mounting, and a quick start guide; no additional accessories are required.
