• Matter-certified for Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings — connect it with major smart home platforms.
• LAN control and Multi-Admin access — use compatible smart home systems together, including when internet access is unavailable.
• Kasa app control, schedules, timers, and Away Mode — manage lights remotely and automate when they switch.
• App-guided installation and a standard wall plate size — follow step-by-step setup for a familiar wall-switch format.

This switch is made for people who want more ways to control the lights already operated by a wall switch. Use voice commands when your hands are full, manage lights from the Kasa app when away from home, or set a schedule for regular routines. Its Matter support also makes it useful in homes where more than one smart home platform is in use.

Which smart home platforms and voice assistants work with it?

The KS205P3 works with Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings through Matter, and supports voice control through Siri, Amazon Alexa, and Google Assistant. Matter’s LAN control allows devices to operate through the local network even when the internet is unavailable. Multi-Admin lets you control the device from multiple systems at the same time, rather than relying on a single smart home platform.

Kasa devices can also be integrated into the Tapo app without replacing hardware. One-tap integration is available when you are logged in to both apps with the same account, bringing supported Kasa devices and other TP-Link smart home options into one app.

• Local network control supports operation without an internet connection.
• Multi-Admin supports simultaneous control through multiple systems.
• Tapo app integration uses the same account and requires no hardware replacement.

Can I control and schedule lights when I am away?

Yes. The Kasa app lets you monitor the light status and turn the switch on or off from anywhere using a smartphone. Scheduling and timer options can automate switching while you are at home or away, so you can set lighting routines without operating the wall switch each time.

Countdown settings provide a way to have the switch turn off after a chosen interval, while schedules can set automatic on and off times. Away Mode randomly switches the light on and off when you are away, a feature intended to make the home appear occupied and deter potential intruders.

• Check light status and control the switch remotely through the Kasa app.
• Choose scheduled or countdown-based switching.
• Use randomized on-and-off switching with Away Mode.

The Kasa app guides installation step by step, so setup does not require understanding master or auxiliary switch configurations.
