Digital Indoor Thermometer/Hygrometer by Clas Ohlson

Convenient and secure: Utilize the free Meross app (compatible with iOS/Android) to effortlessly monitor temperature and humidity levels that matter to you, anytime and anywhere. All data is securely transmitted through the Meross Sensor (via HTTPS & TLS) and securely stored on AWS servers located in Germany. Access all historical temperature and humidity data conveniently stored in the AWS Cloud, allowing retrieval and exportation through the Meross app.

Robust coverage: Experience a powerful range of 30 meters on two walls between the temperature and humidity sensor and the smart hub. The temperature range spans from -40 to 60 °C, with an optimal preference between -10 and 50 °C (extreme temperatures may affect battery life). The humidity range covers 0 to 100% RH.

Compact yet precise: Enjoy a compact design and lightweight build. The sensor components, crafted in Switzerland, ensure accurate measurements. The CR2477 battery typically lasts over a year under normal conditions. The wireless sensor offers flexibility with a hanging thread and 3M double-sided tape.

Alerts and Automation: Receive immediate notifications on your smartphone when the monitored area’s temperature or humidity exceeds set limits. The automation feature simplifies temperature and humidity monitoring. For instance, if the baby room temperature is too high, your Meross Smart Lamp will turn red to alert you.
