TFA 35.1123 Wireless Weather Station with Outdoor Sensor

Keep Track of Indoor Climate and Outdoor Temperature from One Display

The TFA 35.1123 wireless weather station provides an easy way to monitor outdoor temperature and indoor climate conditions from one clear digital display. The supplied wireless transmitter measures the outdoor temperature and sends the reading directly to the base station, while the station monitors indoor temperature and relative humidity.

Designed for everyday use at home or in the office, the TFA LOOK 35.1123 also provides weather symbols, indoor comfort indication, temperature alarms and minimum/maximum readings. A built-in clock, date display, alarm with snooze function and moon phase display make it a practical all-in-one weather and indoor climate monitor.

Wireless Outdoor Temperature Monitoring

The supplied wireless outdoor sensor transmits temperature readings to the base station over a distance of up to 30 metres in open areas. This allows you to check outdoor conditions conveniently without leaving the house.

Indoor Temperature and Humidity

In addition to outdoor temperature, the weather station continuously displays indoor temperature and relative humidity. The integrated comfort indicator helps you assess indoor climate conditions and make informed decisions about heating and ventilation.

Weather Trend at a Glance

Easy-to-understand weather symbols provide a quick indication of changing conditions based on changes in humidity. This gives you a simple visual overview alongside the current indoor and outdoor measurements.

Temperature Alarm and Min/Max Readings

An adjustable temperature alarm can alert you when defined temperature limits are reached. Minimum and maximum values can also be recalled, making it easy to review temperature variations over time.

Expandable Wireless Monitoring

The TFA 35.1123 supports up to three compatible wireless transmitters. Additional sensors can therefore be used to monitor temperatures in other locations such as a bedroom, children’s room, garage or cellar.

Clock, Date and Moon Phase

The integrated clock includes a date display, alarm and snooze function. The display also shows the current moon phase, providing useful additional information alongside the weather and indoor climate readings.
