Smart monitoring for indoor spaces

This Wi-Fi thermometer hygrometer tracks temperature and humidity in real time and sends alerts to the Tuya Smart or Smart Life app when readings move outside preset ranges. It connects to 2.4 GHz networks only and works with Amazon Alexa and Google Home for voice queries. The Swiss-made sensor measures from minus 10 °C to 60 °C with ±0.5 °C accuracy and humidity from 0 % to 99 % with ±5 % RH accuracy.

Suits remote monitoring and automation

Homeowners who want phone notifications and automated scenes for climate control will find the alert and smart linkage features useful. Buyers needing 5 GHz Wi-Fi connectivity or local data access without an internet connection should look at other devices.

Swiss sensor precision drives reliability

The built-in Swiss-made sensor delivers ±0.5 °C temperature accuracy and ±5 % RH humidity accuracy across the full operating range. This specification determines whether the monitor meets the precision needs of the intended application.

Questions about this item

Does the 2.4G Wi-Fi sensor draw enough power to need frequent battery changes if it runs 24/7?

The unit is designed for continuous 24/7 monitoring using a Swiss-made sensor; typical battery life spans months under normal indoor conditions.

What must I already have at home for the hygrometer to connect and send alerts?

You need a 2.4G Wi-Fi network and a smartphone with the Tuya Smart or Smart Life app installed to complete setup and receive notifications.

Can I view readings from this sensor on an older Alexa Echo Dot that only supports voice queries?

Yes — once linked in the Alexa app, you can ask any Echo device for the current temperature or humidity reported by the sensor.
