Hello Again

Now after more than 1 month This is my opinion:

Measurement accuracy About Temperature is 95%

Measurement accuracy About Barometer is 75%

Measurement accuracy About Humidity is  70%

And Forecast is 0%  ( َAlways shows rainy or thunder but we never had even rain )

I Guess forcast is just there to make it pretty and it is useless.

So you can just trust on Temperatures.

Accuracy is much better than that.  Much has to do with proper siting and installation.

Folks share their data to services such as CWOP which constantly judge their station's accuracy so data quality can be improved. http://wxqa.com/

Hello Payam,

Where are you located? The barometric pressure adjusts during the 14-33 day learning mode.  The accuracy standards are as follows:

+/-2° Per unit

+/-5% Per unit

+/-.15inHg

Hello

My Location is Tehran. ( 1488 m  above sea level in my place )

Its more than 33 day that i have this station.

Calibration is automatic and there is no manual setting so I can't do anything more.

The worst thing is forecast , with 0%  accuracy.

This Station is just one step better than a Child Toys. ;))

Hello Payam, 

If you are getting an incorrect forecast and pressure reading, please reset the weather station when your local pressure reading is at 29.92. When your local pressure is at 29.92 unplug the display for 2 minutes. Power it back up. This will start your 14-33 day learning mode over again.

Hello Payam,



The display uses an algorithm to determine your altitude and will adjust your forecasting and pressure based off those readings. This will help with the forecasting and the pressure readings. As far as the time zone being incorrect, the product is designed for North America so that is the time zones that are programed in there. You would need to manually set the time to get it to read correctly.

Payam,  The reset put the unit into a "learning mode".  The pressure reading of 29.92 inches/mercury is the "Standard Pressure" used as a starting point.  The data that is collected by the microcomputer, eg. barometric pressure changes along with all the other weather readings are compared and saved so that your unit can make comparisons of the changes that will be used to predict coming weather.

Do you have outdoor temperature error while the sun is shining onto your 5 in 1 sensor?

Hi Steve

I did reset at 29.92 now its in learning mode again , lets see what will happened this time, again always rainy and thunder or .... ;)

Sensor is out but under shadow and sun never shins onto it

I hadn't any temperature error .

Understood.  With the desert climate, the weather prediction algorithms might not be able to operate successfully.  See how the unit operates now but give it extra time considering the weather conditions in Iran. 

Hope to see it work out for you.  Make sure you keep in in the shade if you want accurate temperatures.

BEST REGARDS,

Steve

Hi

That is Another country located in Desert , loooool
we have desert lands but no one lives there just lizards or scorpions . ;)
Tehrann is capital of iran and surrounded by mountains by north ,
the  altitude of city is between 1200m to 1800  m above sea level .
temperatures could go below zero in winter ( last night 6 c ) and up to 40 c in summer.
so if what u say is right , the company should says this unit only works in europ or china.  loooool

Actually, many of the displays have forecasting heuristics based on North American historical data.

Who knows how they'll work outside the countries Acurite says they support?

Hello Payam,

Let us know if this corrects the issue once the learning mode is complete.

Hello Jennifer

Ok , I will , but what i saw , it is better to show just Pressure and no need to forecast.

weather websites do it very better ,( using satellite information )... but this little unit

based on algorithms cant do it.

Hello Payam,

This unit was designed to show both, and will use the algorithm to determine the information. Please let us know the results once this is completed.
