Weather Station TFA Dostmann Luna Sky Grey — indoor/outdoor thermometer, hygrometer, barometer, AAA battery

The TFA Dostmann Luna Sky Grey is a compact weather station that displays indoor and outdoor temperature and humidity, atmospheric pressure with trend, and the current moon phase. The device shows clearly arranged weather information on a soft blue–yellow–violet gradient background that is illuminated at the touch of a button. It accepts data from up to three wireless outdoor transmitters and also monitors indoor climate and comfort level. Time is set automatically by radio; the station includes two alarm settings with snooze. The base station and one transmitter are powered by five AAA batteries (not included).

Advantages

The Luna Sky provides consolidated indoor and outdoor climate data — temperature, humidity and pressure trends — in an easy-to-read display with weather symbols and a trend arrow. Its illuminated gradient background and detailed moon phase display help visual recognition of current conditions. Wireless support for up to three outdoor transmitters and a radio-controlled clock simplify setup and daily use. Dual alarms with two volume levels and snooze add practical functionality for bedside or household use.

Suitable for

• Home use for monitoring indoor temperature and humidity
• Monitoring outdoor conditions in a garden, balcony or near an entrance (using wireless transmitters)
• Short-term weather trend observation and daily planning
• Users who want a radio-controlled clock combined with weather data and alarm functions

When it may not be suitable

The Luna Sky is battery-powered and intended for household use; it is not designed for continuous professional or industrial monitoring. Wireless transmitters have a limited range (up to 30 m under ideal conditions), so performance may be reduced through thick walls or over longer distances. Batteries are not included, so you will need five AAA batteries for the base station and additional batteries for any extra transmitters.

Key specifications

• Measures indoor and outdoor temperature and relative humidity
• Receives data from up to 3 wireless outdoor transmitters (range up to 30 m, typical conditions)
• Built-in air pressure sensor with trend display (absolute or relative pressure)

How to use

Install the included transmitter outdoors within the specified wireless range and insert batteries into both the transmitter and the base station. The base station will automatically receive outdoor values from up to three paired transmitters and measure indoor temperature, humidity and air pressure. Use the buttons to toggle the backlight, set alarms and select pressure display (absolute or relative). The radio-controlled clock sets time and date automatically; alarm settings and snooze are configured on the base unit.

What to consider before purchase

• Requires five AAA batteries for the base station; additional batteries needed for each extra transmitter
• Wireless transmitter range is up to 30 m under ideal conditions — building materials and obstacles can reduce range
• Not intended for professional meteorological or industrial use
• Display language options include seven languages for weekday/date information

Usage recommendations

Place outdoor transmitters in a sheltered, ventilated location away from direct sunlight and rain for accurate temperature and humidity readings. Keep the base station away from heat sources and drafts to ensure correct indoor climate measurements.
