ESP8266 Weather Station library supporting OpenWeatherMap
...The simple class uses the header date and time to set the clock. NTP-based time class written by Fabrice Weinberg. We fixed many bugs and improved performance and changed the API a little bit. Either compare your code to the updated WeatherStationDemo or read through the upgrade guide.
Ws2300 manipulates the LaCrosse WS-2300 weather station via its RS232/USB interface. It can read and write values, and can continuously log data from WS-2300 to a file or SQL database.
