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.

Requires an Aqara Zigbee hub (Thread/Matter via a Thread-capable Aqara hub).

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
