This set from the TFA.me system for temperature monitoring consists of a Gateway ID-01 and three temperature transmitters ID-A3 with waterproof cable sensors. The transmitters monitor both the temperature in the refrigerator, freezer, pool, aquarium, or terrarium via the cable sensor, as well as the ambient temperature at the transmitter's location. The handy gateway cube is the cornerstone of the TFA.me system. It serves as a receiving unit: up to 50 TFA-ID radio transmitters for various measurement parameters are received and forwarded by the Wi-Fi gateway. This allows the collected values to be accessed online worldwide. A Wi-Fi and internet connection is required for the gateway. Additionally, the transmitters must be within a reception range of up to 100 meters. 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 allow for a manually selectable or automatically changing display of up to five thermo-hygro radio transmitters on the screen. Furthermore, the current time, complete date, or the spelled-out day of the week is displayed in six languages. In addition to monitoring home and garden, this set is ideal for professional applications – for example, in pharmacies, laboratories, or catering businesses, and anywhere comprehensive temperature monitoring is essential. The measurement data is transmitted closely via the internet and can be accessed on the browser-based TFA.me portal – flexibly on your smartphone, tablet, or PC. You can also receive email notifications when defined measurement values are exceeded or not met. Additionally, you can have manual or automated exports of the measured values sent to you via email through the TFA.me portal.
