Load Weather Station software

20889a71fc890355a9adf0d7d0c0d611


1. First download and install these two libraries

You do this by clicking the green button on the above web pages and click the GREEN 'Clone or Download' button and download the zip files for both.

2. Next install these libraries into the Arduino Software

  • Sketch->Include Library->Add .Zip library... then choose the zip file you previously downloaded and install.

3. Now open the Weather Station Demo code...

  • File->Examples->ESP8266 Weather Station->Weather Station Demo

4. Now you will see the Weather Station Demo code and you will need to replace it with the code here WeatherStationDemoCode . Copy and paste all of it.

  • Modify the WIFI settings needed for home and work
  • Copy and paste code into the weatherstation code

5. At this point you should be able to upload your code to the D1 Mini board and enjoy the weather
