## Long description

The TFA-Dostmann 35.1145.54 Silver Indoor Outdoor Thermometer is a compact digital weather station with an LCD display designed for home and small-office monitoring. It provides measurements of indoor and outdoor temperature and humidity, incorporates a barometric pressure sensor, and records rainfall data. The device operates on AA batteries and uses a 433 MHz wireless connection to receive data from remote sensors. Its slim silver housing and clear display are intended for tabletop placement or wall mounting in living spaces, conservatories, or garages.
Advantages
The unit combines multiple environmental measurements on a single LCD panel, reducing the need for separate instruments. Wireless reception at 433 MHz allows placement of the outdoor sensor at a distance from the main display, while battery operation removes the requirement for nearby power outlets. The inclusion of barometric pressure and rainfall data supports short-term weather awareness. The compact dimensions make it suitable for limited spaces and multiple mounting options.
Suitable for
Home monitoring of indoor and outdoor temperature and humidity
Small greenhouses, conservatories, and patios
Garages and workshops where compact, battery-operated monitoring is required
Users who need combined temperature, humidity, pressure and rainfall readouts

How to use
Insert fresh AA batteries into the main unit and into any remote sensors according to their polarity markings. Place or mount the main display in a sheltered indoor location with a clear line of sight toward the outdoor sensor for reliable wireless reception. Install the outdoor sensor in a shaded, ventilated spot away from direct heat sources and dripping water to ensure accurate air temperature and humidity readings. Follow the manufacturer's instructions for pairing sensors and resetting the station if needed; allow a few minutes for sensors to transmit initial readings.
Usage recommendations
For stable measurements, replace batteries at regular intervals and position the outdoor sensor where it is protected from direct sunlight and heavy precipitation. Clean the sensors gently and avoid placing the indoor display near radiators, ovens, or air vents. If signal range is limited, reduce obstacles between the outdoor sensor and the indoor display or relocate the outdoor unit to a higher position.
