## Long description

TFA-Dostmann 35.1129.01 is a battery-powered digital weather station in black with a compact console measuring 210×140×26 mm. The device monitors indoor temperature and relative humidity and receives outdoor temperature wirelessly via a 433 MHz transmitter. The console shows current time and date, thermometer trend information and an electronic barometer-based weather symbol that visualizes likely short-term weather changes. The unit is designed for home or office use and operates on standard 1.5 V AAA/AA batteries; a mains adapter can be used optionally to enable permanent backlight.
Advantages
The weather station provides simultaneous indoor climate readouts and remote outdoor temperature monitoring through a wireless 433 MHz link, allowing quick assessment of room conditions and external temperature. An integrated barometer interprets pressure changes to display a simple weather forecast symbol, and the console indicates temperature trends for easier tracking. Battery operation ensures placement flexibility while the optional mains adapter permits continuous display illumination and adjustable backlight levels.
Suitable for
 Monitoring room temperature and humidity in living rooms, bedrooms and offices
 Checking outdoor temperature near the house using the wireless transmitter
 Keeping track of short-term weather tendencies via barometric symbols
 Situations requiring a compact, battery-operated weather display
Key specifications
 Console dimensions: 210 × 140 × 26 mm
 Power: battery-operated on 1.5 V AAA/AA cells; optional mains adapter for continuous backlight
 Wireless frequency for remote sensor: 433 MHz

How to use
Insert the required 1.5 V AAA/AA batteries into the console (or connect a compatible mains adapter if continuous backlight is needed) and place the wireless outdoor transmitter in a sheltered outdoor location within the manufacturer's specified transmission range. The console automatically receives time and date via the radio signal and synchronizes with the remote sensor to show outdoor temperature. Read indoor temperature and humidity directly from the display; consult the barometer symbol and trend arrows to understand short-term weather development and temperature changes.
Usage recommendations
Position the indoor console away from direct heat sources, windows and humidifiers for accurate room readings. Mount or place the outdoor transmitter in a sheltered, ventilated spot not exposed to direct rainfall or strong sunlight to ensure reliable 433 MHz transmission and correct outdoor temperature measurements. Replace batteries regularly and use the adapter when extended backlight or continuous display is required.
