2026 verdict
Patio doors that should report over Wi-Fi, with no hub, are where the Sonoff DW2-WIFI is the sensor to buy rather than the Eve Door & Window.
It joins 2.4 GHz Wi-Fi directly, uses Bluetooth only while pairing, keeps 90 days of history, sends low-battery alerts, works with Alexa, Google Home and Home Assistant, and is the more affordable of the pair. Apple Home, SmartThings and Matter are not supported, and battery life is not published. Owner response favors the Eve Door & Window, and it is the wider platform sensor: Matter over Thread into Apple Home, Google Home, Alexa, SmartThings and Home Assistant, if a Thread border router is already there, on a half-AA cell rated for 11 months. Neither is for outdoor weather. Use the Sonoff DW2-WIFI on a patio door that only needs Wi-Fi. Use the Eve Door & Window when that door has to live in Apple Home.

What the differences mean
Wi-Fi or Thread
The Sonoff DW2-WIFI uses 2.4 GHz Wi-Fi and needs no hub. Bluetooth is only for pairing. The Eve Door & Window uses Thread and needs a border router before it can join Matter. A patio door in a house with only a router, and no Apple TV or HomePod, can use the Sonoff and cannot use the Eve.
Platforms
The Eve Door & Window supports Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Matter. The Sonoff DW2-WIFI supports Alexa, Google Home and Home Assistant, and not Apple Home, SmartThings or Matter. The platform list is the Eve's scored strength in this pair.
History and battery
The Sonoff DW2-WIFI keeps 90 days of history and sends low-battery alerts, on two AAA cells with no published life. The Eve Door & Window is rated for 11 months on one half-AA cell. History length and a low-battery alert are not published for the Eve, so those rows are not a loss for it.
Where it can sit
Neither sensor is weather resistant. The Sonoff DW2-WIFI measures 70 x 31 x 19 mm and weighs 28 g. The Eve Door & Window measures 52 x 24 x 23 mm, and its weight is not published. Owners still call the Eve awkward on inset sliders because of the included risers.
Which one to buy if
- the patio door should use Wi-Fi and no extra hub
The Sonoff DW2-WIFI joins 2.4 GHz Wi-Fi directly and is the more affordable of the pair.
- that door must show up in Apple Home or Matter
The Eve Door & Window supports both. The Sonoff DW2-WIFI supports neither Apple Home nor Matter.
- you want a 90 day history and a low-battery alert
Both are published on the Sonoff DW2-WIFI. Neither figure is published for the Eve Door & Window.
- you already have a Thread border router
The Eve Door & Window then covers Apple Home, Google, Alexa, SmartThings and Home Assistant on a half-AA cell rated for 11 months.

What owners say
Owners of the Sonoff DW2-WIFI like it once paired: mailbox and garage alerts, decent Wi-Fi reach, Home Assistant, and AAA cells with a low-battery warning. The story before that is pairing pain on modern routers, a magnet gap that is too tight, and batteries that sometimes drain early or fail to return after an outage. Owners of the Eve Door & Window barely mention a pairing fight. They single out a Thread link that stays up, a setup that takes seconds on an iPhone, and strong adhesive, and they warn that the sensor is a poor fit without a border router and that the body plus risers is awkward on some sliders.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions
Which is the better patio-door sensor, the Eve Door & Window or the Sonoff DW2-WIFI?
The Sonoff DW2-WIFI, when the door should report over 2.4 GHz Wi-Fi with no hub. It is the more affordable, with 90 days of history and low-battery alerts, plus Alexa, Google Home and Home Assistant. Owner response favors the Eve Door & Window as the Matter sensor if a Thread border router is already there.
Does the Sonoff DW2-WIFI need a hub the way the Eve Door & Window needs a border router?
No. The Sonoff DW2-WIFI joins Wi-Fi directly. Bluetooth is only for pairing. The Eve Door & Window needs a Thread border router, then supports Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Matter. The Sonoff does not support Apple Home, SmartThings or Matter.
Can either sensor live on an exposed patio in the rain?
Neither is weather resistant. The Sonoff DW2-WIFI and the Eve Door & Window are indoor contact sensors. A covered patio door frame is the sort of opening they are specified for, not a gate in the rain.
How do batteries compare on the Eve Door & Window and the Sonoff DW2-WIFI?
The Eve Door & Window publishes 11 months on one half-AA cell. The Sonoff DW2-WIFI uses two AAA cells and does not publish a life, so it cannot be called longer or shorter. It does publish low-battery alerts and a 90 day history.
Who should buy the Eve Door & Window instead?
Someone whose patio door should appear in Apple Home, Google Home, Alexa, SmartThings or Matter, and who already has a Thread border router. Buy the Sonoff DW2-WIFI for a hub-free Wi-Fi alert and a lower price.
