Weather display TFA Dostmann Sky Black LCD battery-powered wireless thermometer-hygrometer (indoor/outdoor, 0.433 GHz, AAA)

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.

How to use

Install batteries in the base station and the outdoor transmitter according to the enclosed instructions, place the transmitter outdoors within the recommended wireless range, and position the base station on a desk or mount it on a wall. The outdoor transmitter sends temperature and humidity data to the base station via 0.433 GHz transmission. Use the front-panel buttons to view current values, cycle through max/min records and set the clock and alarm. Activate the backlight with the dedicated button for improved visibility in low light.

Recommendations

Place the outdoor transmitter in a shaded, ventilated location protected from direct rain and strong sunlight to ensure accurate outdoor readings. Avoid placing the base station near heat sources or in direct sunlight to maintain correct indoor measurements. Replace batteries promptly when low to maintain continuous wireless transmission and time synchronization.
