Temperature and humidity sensors compatible with Alexa

A temperature sensor that works with Alexa usually means you can ask Alexa what the reading is, and sometimes use it in a routine. The cheapest ones are Bluetooth or Zigbee, and they only reach Alexa through a hub or gateway from the same maker, so budget for that box. Wi-Fi models skip the hub but eat batteries faster or need to be plugged in.

Check these before you buy

  • Bluetooth-only sensors work from your phone when you are nearby. To see readings in Alexa, or from away from home, they need the maker's hub or gateway.
  • If you want a routine like turning on a fan when a room gets humid, check that the sensor appears as a routine trigger in the Alexa app. Some only report a reading.
  • Outdoor, fridge, and freezer spots need a model rated for the cold, and batteries lose charge faster there.

Connects directly 2

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 1

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 hub first 9

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.

Not on this list?

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
