Product information

Description

The TFA WeatherHub 31.4001.02 wireless environmental sensor is designed for accurate temperature measurement with convenient Wi-Fi connectivity. This device allows you to monitor climate data around your home and garden directly through your smartphone using the free WeatherHub application. As part of the SmartHome system, the sensor transmits measured values wirelessly to a gateway module, ensuring you stay informed about your environmental conditions at any time.

Advantages

This environmental sensor offers seamless integration into the WeatherHub SmartHome system, enabling easy mobile climate and home monitoring. It features wireless transmission of temperature data and allows users to retrieve current readings as well as historical values for up to 90 days. The system supports customizable alert limits with push notifications in case of an alarm. Installation is straightforward and quick, and the starter setup can be expanded with up to 50 additional sensors to cover multiple areas.

Suitable for

  • Monitoring indoor temperatures in living spaces or basements
  • Tracking outdoor temperatures in gardens or on balconies
  • Remote climate observation via smartphone
  • Expanding home automation with multiple environmental sensors

When it may not be suitable

This device may not be suitable for users who require continuous local data readouts without an internet gateway or smartphone application. It is also not designed for industrial processes that demand specialized hardwired monitoring equipment.

Key specifications

  • Wireless temperature measurement
  • Wi-Fi connectivity
  • Battery powered by AAA 1.5 V batteries
  • Dimensions of 40 x 28 x 104 mm
  • Compatible with the WeatherHub SmartHome app

How to use

To begin using the sensor, connect the WeatherHub gateway to your network using the provided LAN cable and power plug. Install the free WeatherHub application on your smartphone. Insert the AAA batteries into the wireless temperature sensor and place the unit in your desired indoor or outdoor location. The sensor will wirelessly transmit temperature readings to the gateway, allowing you to view current data and set up push notification alert limits through the mobile app.

What to consider before purchase

  • Requires an active internet connection and gateway for data transmission
  • Designed to work specifically with the WeatherHub mobile application
  • Powered by standard AAA batteries which will require periodic replacement
  • Starter set includes the core components and one temperature transmitter, with expansion options available separately

Ensure the sensor is placed within effective wireless range of the gateway and protect it from direct exposure to severe weather elements if installed outdoors. Regularly check battery levels to maintain uninterrupted data transmission.
