Door and window sensors compatible with Alexa
Most door and window sensors do not talk to Alexa on their own. They are small battery devices on a low-power radio, so almost all of them reach Alexa through a hub first: the maker's own hub, or an Echo that has a hub built in. That hub is the real purchase decision. Pick the hub you will build on, then buy sensors that pair with it, not the other way around.

Check these before you buy
- Find out whether your Echo has a built-in hub. A few Echo models can pair some sensors directly; most cannot, and then the sensor needs its maker's hub.
- Sensors that connect through Matter over Thread need a Thread border router, a small radio some Echo models and other smart speakers have built in. Check yours before you count on it.
- Plan on using the sensor to start an Alexa routine, like a light turning on when a door opens. Confirm the sensor shows up as a routine trigger in the Alexa app, not only as a status tile.
Connects directly 1
The maker built this connection to Alexa. Some of these still need the maker's own hub, and the line under each product says so.
Connects through Matter 3
These join Alexa through Matter, a shared standard, so no maker's cloud sits in the middle. The ones that use Thread also need a Thread border router, a radio built into some smart speakers and hubs.

Needs a Thread border router (an Aqara Hub M3, a HomePod, an Apple TV 4K, or a recent Echo).

Matter-enabled; needs a Matter controller (Thread mode) or an Aqara Zigbee hub (Zigbee mode).

Matter over Thread; needs a Thread border router (IKEA DIRIGERA, Apple/Google/SmartThings hub). Also operates as Zigbee with a DIRIGERA hub.
Needs a hub first 11
These reach Alexa only through a hub, usually the maker's own. If you do not own that hub yet, add its price to the device's.

That does not mean it will not work with Alexa. It means we have not confirmed a path for it yet, and we add connections as we confirm them against the maker's documentation. How we check
