## Summary description

tfa dostmann Oak is a battery-powered indoor/outdoor thermometer and hygrometer that measures temperature and humidity for both indoor and outdoor locations. It displays trends for hygrometer and thermometer readings, runs on AA alkaline batteries, and supports use with wireless sensors (product supports up to three sensors per offer). Ideal for home climate monitoring and weather observation.

## Long description

The tfa dostmann Oak is a battery-powered indoor/outdoor thermometer and hygrometer that combines weather information, time and comfort indicators in a compact unit with a real oak frame. It receives outdoor data from up to three wireless transmitters, shows animated weather forecasts and symbols, and displays time, date, weekday and moon phase. The device also indicates indoor climate with a comfort zone display and ventilation recommendations and can be powered by AA batteries or a mains adapter for backlight and continuous operation.
Advantages
The Oak station provides a wide range of environmental data on a single screen: outdoor and indoor temperature and humidity, air pressure and trend indicators, plus animated weather forecasts. A comfort zone indicator and a window/ventilation symbol help to maintain a pleasant indoor climate. The oak frame provides a natural look for home interiors and the unit supports up to three wireless outdoor sensors for flexible placement.
Suitable for
Home owners who want quick overview of indoor and outdoor climate
People who monitor room comfort and ventilation needs
Users who need a radio-controlled clock with alarms and snooze
Households that may add up to three remote transmitters for several outdoor locations
When it may not be suitable
This station relies on wireless transmitters for outdoor measurements and a radio signal for the time; performance depends on transmitter placement and signal reception. If you need professional-grade meteorological accuracy or wired sensor connections, this consumer device may not meet those requirements.
Key specifications
Indoor and outdoor temperature measurement
Indoor and outdoor relative humidity measurement
Support for up to 3 wireless outdoor transmitters (range up to 60 m in open field)
Animated weather forecast with symbol and trend display
Relative air pressure indication and trend
Radio-controlled clock with date, weekday (7 languages) and moon phase

Maximum and minimum value memory for temperature and humidity
Backlight with 3 brightness levels (requires mains adapter for illumination)
Frame made of solid oak wood
Power: AA batteries (battery operation) or mains adapter (for backlight)
How to use
Insert AA batteries into the main unit and, if available, into each wireless transmitter. Place the outdoor transmitters in the desired external locations within the stated wireless range and allow time for the station to receive signals. If you prefer constant backlight, connect the mains adapter. Use the menu and buttons to set the radio-controlled clock, alarms and snooze interval, and to review max/min values, trends and comfort indications. Follow the included manual for pairing additional transmitters.
What to consider before purchase
Check that transmitter placement will be within the wireless range (up to 60 m open field; obstacles reduce range)
Decide if you want mains-powered backlight or battery-only operation
Confirm the need for up to three outdoor sensors and their separate purchase if required
Ensure radio reception for the radio-controlled clock in your area
Usage recommendations
Position outdoor transmitters sheltered from direct rain and extreme heat, place the main unit where the display is easily visible, and replace batteries annually or when low-battery indication appears to ensure continuous monitoring and accurate trends.
