## Long description

TFA Dostmann Sky Black is a battery-powered wireless weather display with a clear LCD for monitoring indoor and outdoor temperature and humidity. The system consists of a compact black base station and a separate outdoor transmitter communicating at 0.433 GHz. The base station measures indoor temperature and humidity, shows weather symbols and a one-day forecast, and provides time, date and alarm functions. Max/min values are displayed permanently with an additional memory for manual reset. The unit is designed for wall mounting or desktop placement and runs on AAA 1.5 V batteries.
Advantages
The display combines indoor sensors and an external wireless transmitter to provide simultaneous readings for indoor and outdoor conditions. Weather icons and a next-day forecast make it quick to assess current conditions at a glance, while permanently visible max/min values and a manual memory allow tracking of extremes. The device includes radio-updated time and a snooze-capable alarm clock, and the two-colour LCD with backlight ensures good readability in varied light conditions. Compact plastic housing and battery operation enable flexible placement.
