Smart temperature and humidity monitor

This 2-pack of WiFi thermometer hygrometers lets you track indoor conditions from anywhere using the Tuya Smart or Smart Life app. Each unit measures temperature from -10°C to 60°C with ±0.5°C accuracy and humidity from 0% to 99% with ±5% RH accuracy. Data is stored free in the app for export and historic review. A clear LCD shows live readings on the device itself.

Suits homes needing multi-room alerts

These sensors work well for anyone who wants push notifications when temperature or humidity drift outside preset ranges. They also support voice checks via Amazon Alexa and Google Home and can trigger Tuya Smart scenes such as turning on an AC or dehumidifier automatically. Buyers who need 5 GHz Wi-Fi connectivity should look elsewhere because only 2.4G networks are supported.

Swiss-made sensor with 2.4G Wi-Fi

The Swiss-made sensing element provides the quoted accuracy around the clock. Connection is limited to 2.4 GHz Wi-Fi, so the monitor will not join a 5 GHz-only network. This single constraint decides whether the device fits your existing wireless setup.
