My old station died. :( But this Kentfaith FT-0300 is a nice clean and easy to set up home weatherstation.
Now the specific concerns.
This is a home-use, internet linked weatherstation, quick to set up and easy to get online. BUT...
There is no way to calibrate the wind vane. Many homes are not oriented North South on any wall so the wall mount options make it relatively impossible to ensure your wind direction is correct. This is compounded by the oblong mounting pole which forces the set up to require a North-South oriented mounting surface. (previous "Professional" weather stations all had a mechanism to calibrate this sensor).
Additionally there is no way to calibrate the temperature sensor at the console either--while one expects it to arrive calibrated, that is not how professisonal weather stations work.
Likewise, too, for the barometer--there is no way to calibrate this for your locations altitude. Hopefully WeatherUnderground and WeatherCloud are making the adjustments based on the locations. Also on the Barometer when I switched over to this new station, the Barometer reading was 8 Hpa lower than the other functioning barometer (which was much closer to the local readings at the local airport). While relative barometric pressure is the indicator, it would be nice to be calibrated and consistent with the actual Pressure. A little note on the Barometer is that there is no trend indicator. Trend would be nice on the console but I guess most people are looking on their phones or computer so that will have trends on the sites. All in all it is a nice station but not really professional.
Finally, the manual has a section on firmware updating but no such updating files exist online so this is a useless feature and useless to put into the manual.
