Aqara Climate Sensor W100

The Aqara Climate Sensor W100 from Aqara uses Matter over Thread to connect to your smart home. Thread is a low-power mesh network built for devices like a Humidity, Temperature, Thermostat. Devices pass messages to each other, so the mesh gets stronger and reaches further with every router you add.

In a Thread network, the Aqara Climate Sensor W100 works as a End Device (MTD).

Border Router (TBR)

A Thread Border Router connects your Thread devices to your home network, so no extra hub is needed.

Router (FTD)

A Thread Router stays powered on and relays messages for other devices, extending the range of your network.

End Device (MTD)

A Thread End Device talks to nearby routers and does not relay messages, which saves power and battery life.

Every Thread router you add makes your mesh stronger and extends its range. See all Thread devices →

Frequently Asked Questions

Does the Aqara Climate Sensor W100 need a smart hub?

Yes. The Aqara Climate Sensor W100 needs a Thread Border Router to reach your home network, plus a Matter controller from your platform. Most devices handle both, like a HomePod mini, Google Nest Hub (2nd gen) or Amazon Echo (4th gen). See all border routers

Does the Aqara Climate Sensor W100 work without internet?

Yes. Matter runs on your local network, so the Aqara Climate Sensor W100 keeps working when your internet goes down. Remote access, voice assistants and some Aqara cloud features may still need a working connection.

Does the Aqara Climate Sensor W100 work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Aqara Climate Sensor W100 is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Humidity, Temperature, Thermostat devices. Support for newer device types can differ per platform.

Do I need the Aqara app to use the Aqara Climate Sensor W100?

No. Any Matter hub can set up and control the Aqara Climate Sensor W100 without the Aqara app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Aqara app.

How do I set up the Aqara Climate Sensor W100?

Open your smart home app, choose to add a device and scan the Matter QR code on the Aqara Climate Sensor W100 or its packaging. You can also type in the 11-digit Matter code instead. The app guides you through the rest. Keep the code safe, you need it again after a reset.
