This model is an 6 sensor in one wireless weather station with USB connectivity to your PC and automatic internet upload to Wunderground website. Note that this won't work with a Mac. Once set up you can check your weather station data from any where using the wunderground website and mobile app. But unlike the Wifi version of this unit your PC must be left on for the wunderground update to function.
The Youshiko wifi weather station has 6 sensors in a single unit for you to position outside, preferably away from buildings if the wind data is to be accurate. The transmission range is 150m and and can pass through one or two walls to reach the receiving console. The receiving console just has a single power cable and has a USB connection to your PC (Mac not supported). It comes with the Weather Tool PC software and lets you extract CSV and spreadsheet data. Unlike the Wifi model there is no separate indoor sensor for temperature and humidity supplied. If you need extra temperature sensors you should go with the wifi model.
This advanced model comes with a simple and attractive display unit. The display itself can be set to loop between 256 colours or you may choose one of 8 colours manually, another option is to have the display colour automatically change with the outdoor temperature. Apart from your weather data you'll see the time, calendar and day of the week.
The weather station unit in your house receives the data from the 6-in-1 weather sensor via 868 MHz RF transmission.
You can see both the indoor and outdoor temperatures and humidity, and also a comfort indication.
For wind you can see the gust and average wind speed in a selection of units (mph, m/s, km/h, knots). Both real time and prevailing wind direction are available.

The display unit incorporates a weather forecast function e.g. sunny, partly cloudy, cloudy, rainy, stormy, snowy.
One special feature is a buzzer alarm clock with ice pre-alert function to warn you if ice is likely.
For barometric pressure you can view relative or absolute readings in hPa, inHg, mmHg, plus these a chart of the pressure change for the last 1, 3, 6, 12, 24 hours.

There is a flashing indicator and LED indicator for weather alerts.
The back light can be set to 3 modes of brightness: High, Low and Off.

This is a great weather station at the lower mid-range price point. If you own a PC and typically leave it running then this station is also a good option for uploading to Wunderground website. The outdoor sensors offer the same readings as the more expensive wifi model. Though it lacks a separate indoor temperature / humidity sensor and the option to connect multiple of these. Still if you would like to extract data from unit and work with your own csv and spreadsheet files this unit offers that.
