Pros and cons

According to our motion detector for alarm systems expert

You receive a notification right away as soon as a door or window is open.
The small design barely stands out in your window frame.
The battery lats up to 5 years, so you don't have to replace it often.
You always need a eufy HomeBase (HM Pro, HB3, or HB2) to use the sensor.

Description

The eufy Entry Sensor E20 secures your doors and windows. You connect your device to the app when you receive it. To use this sensor, you always need a eufy HomeBase (HB Pro, HB3, or HB2). As soon as someone opens a door or window, you'll get a notification right away via the eufy app. This way, you'll always know what's going on, even when you're not home. The sensor is also small, so it fits on almost any frame without standing out. The battery lasts up to 5 years, so you won't have to worry about an empty battery. With this sensor, you can be sure your windows and doors are closed. That gives you a safe feeling, and it helps prevent children or housemates from accidentally leaving a door open.

Review is 7,3 out of 10.

Great sensor

button to temporarily bypass the alarm
A good battery on paper
The magnetic part is the same height as the sensor. As a result, it protrudes significantly when mounted on a window frame.

Battery life sounds very good. But I won't be able to judge whether it is true until a few years from now.

Great and affordable sensor.

Easy to install and connect to the Eufy homebase via the app
The adhesive strip can also be attached to the side of the sensor, allowing you to position the alarm in various ways.
You can set the alarm to different volumes via the app.
It is a bit of a hassle to open the slider. I wanted to try this out even though the battery was already in it.

See the pros and one minor drawback above. I also have Eufy cameras, and now this sensor. I can now see at a glance if everything is okay around the house.
