Sonoff DW2-WIFI
Winner
Sonoff DW2-WIFI
Buy on Amazon USA
It connects straight to 2.4GHz Wi-Fi, works with Google Home, Alexa, Home Assistant and IFTTT, and adds low battery alerts plus 90 days of history the Centralite does not document. The Centralite Micro Door Sensor answers with a higher owner rating and, on paper, a longer list of confirmed integrations through its Zigbee hub, Alexa, Samsung SmartThings and Home Assistant, though several of its other specs, including battery type and life, are left unstated. Choose the Sonoff DW2-WIFI for a cheap, hub-free sensor with richer alerts and history, and the Centralite Micro Door Sensor if a Zigbee hub is already running and its rating matters more.

What the differences mean

What it connects to

The Sonoff DW2-WIFI joins 2.4GHz Wi-Fi directly with no hub or gateway. The Centralite Micro Door Sensor is Zigbee and needs a Zigbee hub such as SmartThings or Home Assistant.

Alerts and history

The Sonoff DW2-WIFI sends low battery alerts and keeps 90 days of open and close history. The Centralite Micro Door Sensor's alerting beyond door and window state, and its history logging, are not documented.

Setup

The Sonoff DW2-WIFI can be tricky to pair on a modern router until the older Wi-Fi 'b' protocol is enabled, a fix its own manual does not explain. The Centralite Micro Door Sensor pairs the way any standard Zigbee HA 1.2 device does, to whichever Zigbee hub is already running.

Documented specs

The Sonoff DW2-WIFI publishes its battery type, connectivity and integrations in detail. The Centralite Micro Door Sensor leaves its own battery type, battery life and several alert types unstated.

What owners say

Sonoff DW2-WIFI owners talk mostly about what it enables once it is running: a ping when the mailbox opens, a notification when the garage door lifts, an alarm trigger wired into Home Assistant, all with no separate hub to buy. The most repeated complaint by far is pairing, many owners hit a generic error trying to join the eWeLink network on a modern router, and the fix, enabling the older 'b' Wi-Fi protocol, is not in the manual. Beyond that, owners note the included magnet needs a very small gap to trigger reliably, so a few swap in a stronger one, and while most report long battery life on the AAA cells, a minority describe heavy drain or a sensor that will not reconnect after a power outage.
