## Long description

TFA WeatherHub smart home environmental sensor is a compact wireless device that measures temperature, humidity, rainfall and wind speed. The unit features a built-in display in a white housing and transmits measured values via Wi‑Fi to a gateway for remote access on smartphones and the WeatherHub app. Power options include AC (via gateway for system), solar and replaceable AAA/AA batteries (1.5 V), allowing flexible installation outdoors or near the house. The sensor integrates into the WeatherHub SmartHome system for continuous climate monitoring, historical data recording and alerts.

How to use
Install the transmitter at the location where you want to measure climate values—ideally mounted on a pole or sheltered, ventilated position for accurate temperature and humidity readings and positioned for unobstructed rainfall and wind measurement. Connect the WeatherHub Gateway to AC power and LAN if required, pair the transmitter with the gateway following the app instructions, and enable Wi‑Fi/cloud synchronization. Use the built-in display for immediate local readings and the WeatherHub app on your smartphone to view live data, historical charts (up to 90 days) and configure alert thresholds. Replace AAA/AA batteries when low or rely on the solar option where available to extend battery life.
Usage recommendations
Place temperature/humidity sensors away from direct sunlight and heat sources, mount the rain gauge level on a clear spot away from obstructions, and install the wind meter at a suitable height free from nearby buildings or trees for accurate wind readings. Regularly check battery status in the app and keep the gateway connected to a stable internet source for continuous remote monitoring.
