Buy at Amazon AUThe Aqara T1 is a wireless sensor that monitors indoor temperature, humidity and air pressure in real time. It stores historical data in the cloud and can send notifications when readings reach preset levels. The sensor runs for up to 2 years on a button cell battery and works with Apple Home, Amazon Alexa, Google Home, Matter and other platforms via an Aqara hub.
Features and specifications in this description are as the brand describes them.
The Aqara Temperature and Humidity Sensor T1 is a wireless climate monitor for indoor spaces. It measures temperature, humidity and air pressure continuously, displays current readings and historical data in the Aqara HOME app, and can notify you when any of these values reach a threshold you set. The brand says it uses a Sensirion industrial sensor for measurement, claiming humidity accuracy of ±3 percent and temperature accuracy of ±0.3°C.
You can use this sensor to trigger automations with other Aqara smart home devices. For example, the brand describes using it to turn on a bathroom ventilation fan when humidity rises during a shower. Once connected to an Aqara hub, the sensor works with Apple Home, Amazon Alexa, Google Home and Matter, and integrates directly with Samsung SmartThings and Yandex Smart Home. It stores data in the cloud without requiring a subscription to view historical records.
Power comes from a single button cell battery, which the brand claims lasts 2 years or more. The sensor has no built-in display; you read all data through the app. The T1 version supports over-the-air updates, which the brand says improves stability and functionality compared to earlier Aqara models.
Research-based: compiled from the manufacturer's information and Australian retailer listings. NXT Smart Home has not tested this product.
Best for: Smart home users with an existing Aqara hub or Zigbee setup wanting precise indoor climate monitoring and automated climate control without recurring subscription fees.
The Aqara Temperature and Humidity Sensor T1 (model TH-S02D) is a compact wireless climate monitor designed for indoor residential spaces. Measuring 36 × 36 × 9 mm and weighing 12 grams, the device monitors ambient temperature, relative humidity, and atmospheric pressure. According to Aqara and Australian retailer Officeworks, the unit uses an industrial-grade Sensirion sensor capable of detecting temperatures from -20 °C to 50 °C (with ±0.3 °C accuracy) and humidity levels between 0 and 100% RH (with ±3% accuracy). The sensor communicates over Zigbee 3.0, records historical readings to the Aqara Home app without an ongoing subscription, and supports over-the-air firmware updates.
This sensor suits Australian households looking to automate heating, cooling, or ventilation around specific environmental triggers. For instance, Aqara notes that the sensor can trigger exhaust fans when humidity spikes, provided the environment remains non-condensing. It is well suited to renters and homeowners who already use an Aqara hub or a Zigbee 3.0 coordinator like Home Assistant, as it mounts with adhesive tape and requires no hardwiring. It will not suit users seeking a standalone gadget with direct Wi-Fi pairing, nor those who prefer a physical on-device display to view room conditions at a glance.
Because the T1 runs entirely on an included CR2032 button cell battery—rated by Aqara for up to two years of life—it does not require Australian 230V mains power or an AC adapter. However, the device has no built-in Wi-Fi hardware and cannot communicate directly with a standard home router. Australian retailers like Officeworks and SmartHome Australia note that operating the T1 requires a compatible Zigbee 3.0 bridge. When paired with a Matter-enabled Aqara hub, it bridges into Matter, Apple Home, Google Home, and Amazon Alexa ecosystems. Third-party Zigbee setups, including Home Assistant, are also supported per retailer documentation. The sensor is backed by a 12-month manufacturer warranty from local retailers, alongside standard statutory protections under Australian Consumer Law. Because the unit lacks water resistance and is rated only for non-condensing indoor conditions, it should not be installed outdoors or directly exposed to shower spray.

I had an older revision of this product for my HomeAssistant setup, and decided to get more since they work so well. And new version also works without any issues. When I compare graphs from old model with this one I fee ...

The Temperature and Humidity sensors are working as described. They were easy to integrate into home assistant and i would definitely recommend them. They are small and accurate.

Great product that works well with both Aqara’s app and Apple Home Kit. It’s also a lot smaller than a Philips Hue sensor which is nice. Note that you do need an Aqara hub for it to work.

Great little device. One sets up and run it and connect it to your Hub. What you can do from there is then expose that to matter or connect the application into Alexa or Google home and run your routines based on the tem ...

I bought two and I've not had them for about a week. The batteries are now down to 50% and one lost contact. I think this is all to do with my zigbee mesh not being strong enough yet.

Received 4 Aqara T1 temperature and humidity sensors. Batteries were very low and had to be replaced. Not happy with that.
