How these picks were selected

Every pick is a Matter sensor sold in the US with a store offer on file. Sensors with a CSA certificate on file for the exact model come first, then those with a product photo, then those with the most search interest. Each pick says whether its record lists Alexa; where it does not, confirm Alexa support with the maker before buying.

How to choose a Matter sensor for Alexa

  • Alexa listing: the records for the Aqara W100, Eve Motion, Aqara Door & Window Sensor P2 and Eve Door & Window list Amazon Alexa, and each maker’s product page names Alexa for it; the Eve Motion three-pack record and the Meross MS605 record do not. Where Alexa is not listed, confirm with the maker and with Alexa that your Echo setup supports that Matter sensor type.
  • Network: every pick connects over Thread, so it needs a Thread border router as well as a Matter controller. Check that your Echo or another device in your home acts as one.
  • Certificates: each pick has a CSA certificate on file for its model; the certificate does not establish the firmware shipped with a retail unit.
  • Pack: the Eve Motion three-pack and the Eve Door & Window offers are three-packs; the single Eve Motion record links a single sensor as well. Compare per sensor.
  • Sensor type: motion sensors (Eve Motion) detect movement, contact sensors (Eve Door & Window, Aqara P2) detect a door or window opening, the Aqara W100 reports temperature and humidity, and the Meross MS605 is a presence sensor. Choose by the routine you want to trigger.
