This set from the TFA.me temperature monitoring system consists of a gateway ID-01 and three temperature transmitters ID-A3 with waterproof cable sensor. The transmitters monitor the temperature in the refrigerator, freezer, pool, aquarium or terrarium via the cable sensor as well as the ambient temperature at the transmitter's installation location. The handy gateway cube is the cornerstone of the TFA.me system. It acts as a receiver unit: up to 50 TFA-ID radio transmitters for various measured variables are received and forwarded by the WLAN gateway. This means that the measured values can be called up online worldwide. A WLAN and Internet connection is required for the gateway. In addition, the transmitters must be located within a maximum reception range of 100 metres. Thanks to its own display and internal sensors, the gateway also functions as a digital thermo-hygrometer for the indoor climate at the installation site. Five channels also allow up to five thermo-hygro radio transmitters to be shown on the display, which can be selected manually or changed automatically. In addition, the current time and the full date or the day of the week are displayed in six languages. In addition to monitoring the home and garden, the set is ideal for use in the professional sector - for example in pharmacies, laboratories or catering establishments and wherever comprehensive temperature monitoring is essential. The measurement data is transmitted closely via the Internet and can be called up on the browser-based TFA.me portal - flexibly on your smartphone, tablet or PC. At the same time, you can be notified by e-mail if defined measured values are exceeded or not reached. You can also have manual or automated exports of the measured values sent to you by e-mail via the TFA.me portal.
