Hi all, thanks for your patience.

Hi jarekh3,

I think you are from Poland, so why are you entering Pacific Time? I think you have the same time as here in the Czech Republic.

This is my settings:

Code:

TimeChangeRule CEST = {"GMT+2", Last, Sun, Mar, 2, 120};       //Central European Summer Time -  "GMT + 2"
TimeChangeRule CET  = {"GMT+1", Last, Sun, Oct, 3, 60};        //Central European Time -  "GMT + 1"
Timezone myTZ(CEST, CET);

Could you try the same?

This was my first setting but since there were problems I came back to the  "clean" configuration.

You can connect the LCD to any I2C connector on the RX board and run the same software. If it will work, we can discard any hardware problem.

With the weatherduino software loaded, try to perform a factory reset by pressing the push button for 5 seconds, this will clean the eeprom.

This RTC has been set by the NPT via the WeatherDuino software, was mounted as  "clean" 01-01-2000 00:00 (Real time is 22:23):
but the program displays this:


BUT! 
 I have in home one more RTC DS3231!
He has been working perfectly for two years on the Arduino aquarium lamp driver. I will try to remove it tomorrow and connect to the board.
