In here you'll find the code to build your own small weatherstation.
The idea was to create a simple and fast environment to send, store and display weather related data on a dashboard.
For this I've hooked a BME280 sensor to some Wemos D1 (ESP8266 compatibles) boards.
The boards are sending their data via wifi every x minutes to the dashboard's api.
Feel free to change, share and improve the code.

Here is a video, showing how I build the stuff:
