Kasa Smart Motion Sensor Switch ES20MP2

Motion detection, adjustable brightness, and daylight sensing bring more control to a wall switch than a basic on/off setup. The Kasa ES20MP2 can turn connected lights on when it detects movement and switch them off after a preset time, which is useful when your hands are full or you don’t want to hunt for a switch in a hallway. You can also set brightness from 1% to 100%, use voice control, and manage settings in the Kasa app. This two-pack is designed for single-pole wiring, so check your existing switch and wiring before choosing it.

Highlights

The main draw is combining motion detection with dimming in the switch itself. In a hallway, for example, you could have the light come on when you walk through and turn off after the selected interval, daylight detection can help prevent it from switching on when the room is already bright. That’s a more flexible approach than relying on a simple motion-triggered light with no app settings or brightness adjustment.

The switch uses 2.4 GHz Wi-Fi and requires a neutral wire. It works with Alexa, Google Assistant, and Samsung SmartThings, and no hub is required. Away Mode can turn devices on and off at different times to make it appear that someone is home. Keep in mind that this switch is for single-pole configurations only: it isn’t compatible with 3-way or multi-location setups.

How to use it

Setup is guided through the Kasa or Tapo app, where you can configure motion triggers, brightness, and the delay before lights turn off. App and voice control add options beyond automatic operation, while the daylight sensor can keep the lights off during brighter parts of the day. Firmware updates are managed through the app.

Installation involves household wiring, not just connecting a wireless accessory. The product requires a neutral wire, and the instructions recommend consulting an electrician if you’re unfamiliar with electrical wiring. Before starting, identify whether your switch is single-pole and whether a neutral wire is present, the app-guided process doesn’t change those requirements.

Practical tips

Think about where motion-triggered lighting would actually help: a hallway you cross with laundry, a bedroom entrance, or a restroom where hands-free switching is convenient. Set the brightness and shutoff timing around that routine rather than assuming one setting will suit every space. Dimming gives you room to choose a lower light level, while daylight detection is useful where natural light varies during the day.

A solid pick if you want a smart wall switch that combines motion automation, dimming, and app or voice controls. If you only need basic automatic lighting, a simpler motion-sensing option may be enough. Not the best choice if your wiring is 3-way, there’s no neutral wire, or you need a switch for a multi-location setup.

Before you decide

Does it work with a 3-way switch? No. It is designed for single-pole configurations and isn’t compatible with 3-way or multi-location setups.

Does installation require a neutral wire? Yes. The product specifies a neutral wire, and recommends an electrician if you’re unfamiliar with wiring.

Can it dim the lights? Yes. Brightness is adjustable from 1% to 100%, alongside motion and daylight-based settings.

Is it worth it?

The ES20MP2 makes sense if you want motion-triggered lighting and adjustable brightness in a smart switch, and your wiring matches its single-pole, neutral-wire requirements. Its app, voice controls, and daylight detection offer more ways to tailor everyday lighting than a basic switch. The tradeoff is that its installation requirements rule out some homes and switch locations, if your setup is 3-way or lacks a neutral wire, this isn’t the right fit.
