Weather Station
============================================

You can download the tutorial's final sample project from this Github Page: https://github.com/myvobot/examples/tree/master/weather_station

Introduction
----------------------

Let's say you are going to use the SyncSign as a fridge magnet. It will let you know the weather condition before breakfast every morning.

Then you can write a Plug-in runs on Hub, which inquires the local weather at 8 am every day, then render the icon and text on the SyncSign.

The Plug-in consists of these components:

- Periodic HTTP Request to the Web API of weather information
- Usually, the response is a JSON format result
- Parse the JSON and extract the data you need (temperature, humidity, etc.)
- Create a layout and send it to the SyncSign

Setup
----------------------

- Sign-up a free account and obtain an API Key from [OpenWeatherMap](https://home.openweathermap.org/api_keys)
- Replace the placeholder of OPENWEATHERMAP_APIKEY with your API key
- Edit CITY_NAME & COUNTRY_CODE

Deploy and Run the Plug-in
---------------------------

Then you can deploy the code to the Hub and see what would happen.

.. 假设您把XXX作为一个冰箱贴，希望每天在早餐前可以看到今天的天气情况。那么，你可以让Hub在每天早上的8点钟获取当地的天气信息，然后在display上显示一个图标和文本。根据这个场景，编写的EAPP主要由以下单元组成：

.. - 定时发起一个HTTP REQUEST，获得天气信息，这通常是一个JSON格式的数据；
.. - 分析天气信息，提取出需要显示的内容；
.. - 创建显示描述，发送给Display显示。

.. Test

.. Congratulations...

Summary

In this tutorial, you have learned how to write a Hub App with web service integration. We hope you enjoyed this tutorial, and I look forward to seeing you again!
