A vertical weather forecaster that shows indoor and outdoor temperature and humidity, pressure and a self-setting clock. It lists no wind or rain sensing, so it is a forecaster, not a full weather station.

Overview
A bedroom, kitchen or home weather center can use this vertical display, which shows indoor temperature and humidity plus outdoor readings sent by a wireless sensor in the backyard. Barometric pressure and wind chill, dew point or heat index appear too, and an atomic clock sets the time.
Self-calibrating forecasting and an atomic clock make it a useful shelf or wall clock as well as a forecaster. The outdoor sensor feeds temperature and humidity, and the display adds pressure based extras. The limitation is scope: wind and rain are not part of what it reports, and the listing disagrees with itself about how far ahead it forecasts.
Who it's for
A household wanting a glanceable forecast and the outdoor temperature in a living space gets what it needs here. Time sets itself through the atomic clock feature. Gardeners or campers who need wind and rain readings should look at a full station instead.
Pros and cons
- Indoor and outdoor readings
- Atomic clock sets time itself
- Adapter and sensor included
- Battery backup for the display
- No wind or rain data
- Forecast horizon stated inconsistently
- Sensor batteries not included
Performance notes
The outdoor sensor sends temperature and humidity by radio to the display, and a built-in barometer with self-calibrating logic produces the forecast. The display runs from the included adapter, with batteries as optional backup. The atomic clock feature sets the time automatically.
