A web controlled switch based on ESP8266 devices such as the NodeMCU and WeMos D1.

The code is written in modern C++ using Visual Studio with VisualMicro add-on.

Before opening the solution make sure that you've installed both Esp8266 and Azure IoT SDK libraries. The best way is to use Arduino IDE (download from http://https://www.arduino.cc/en/Main/Software).

Note: use the Win32 application (Windows Installer) and not the "Windows App" version.

First add esp8266 boards to board manager:

• Open Arduino IDE
• Open preferences (Files -> Preferences)
• Copy: http://arduino.esp8266.com/stable/package_esp8266com_index.json to "Addtional boards Manager"
• Press 'Ok'

Install esp8266 boards

• Open boards Manager (Tools -> Board:xyz -> Boards Manager)
• Navigate to esp8266 by esp8266 and click install

The project needs the following libraries:

• AzureIoTHub
• AzureIoTProtocol_HTTP
• AzureIoTProtocol_MQTT
• AzureIoTUtility

All of those can be installed using Arduino Library Manager (Sketch -> Include Library -> Manage Libraries...)

After adding board support and installing the libraries above you can open the solution file using Micro Studio and compile.

Build the circuit by following the instructions here

Download files for printing from here.

Look at the configuration.h file, here you can set the default access point mode router credentials.

Once you flash the device, you should point your computer/phone/tablet to the device Access Point SSID, and go to settings: http://192.168.4.1/appkey/setup

Once you select the local Access Point and reset the device. Use a browser that is connected to the same network and browse to: http:///appkey

to make the communicationm with the device secured, change the appkey in the configuration file to any secret path you like.

Enjoy,
