[编辑] 1 Overview

AC 85V - 250V Smart Plug
ESP8285 inside
250V 10A relay
Shell size 53mm x 53mm x 27mm

[编辑] 2 Quick Start

插座通电，等 6 s 左右，指示灯 1 秒左右慢闪，表示在等待配网

如果不在慢闪，长按按钮 10 秒

手机连接 2.4G WiFi ，微信扫描二维码，点 "配置设备上网"

按提示输入 WiFi 密码，点 “连接”，等待配网完成（注意，设备目前只支持 2.4G，不支持 5G WiFi）；此外企业级安全认证也暂不支持）

WiFi 配置完成后，微信自动进入局域网发现设备模式，其会列出设备列表

点击第一个设备，进入页面，在页面最下面会有 “绑定设备” 按钮（如果已经绑定过改设备，最下面的按钮为“进入公众号”），点击按钮，完成设备绑定

完成后，点“进入公众号”，在公众号菜单的 “智能设备”，即可列出你绑定的所有设备，点一个设备，即可进入设备控制页

其他人需要控制设备，需要先连接到同样的路由器，在设备通电的情形下，扫描同样的二维码，点“设备已联网，跳过此步”，直接“发现”、“绑定设备” 即可在公众号菜单“智能设备里控制

其他说明：

短按按钮，手动开关控制器
长按 10 秒按钮，恢复出厂设置

[编辑] 3 Open API (MQTT)

微信扫码绑定设备后，进入公众号:

公众号下面的菜单 "Devices" 列出你所绑定的所有设备
选择您的插座，进入设备控制页
点右上角，在弹出的菜单里选“复制链接”
粘贴到浏览器里，访问之，查看页面源码，即可获得你的插座的关键控制参数：

var devid = YOUR_DEVICE_ID;
var mqtt_uname = xxxxxxxx;
var mqtt_pass = TTTTTTTTTTTTTTTT;                           < ---- mqtt server token, 3600s life time
var mqtt_server = xxx.xxx.xxx.xxx;
var mqtt_port = xxx;

[编辑] 4 Open API (HTTP in LAN)

注意：设备的安全策略借助 WiFi 路由器的密码实现，即：认为被授权连接入 WiFi 路由器的用户，皆为可信用户

设备默认开启一个 HTTP 服务，发送如下 http 请求，可完成设备的状态控制，此方式不依赖外网 MQTT 服务，可用作隔离外网环境下的，本地局域网控制：

[编辑] 4.1 Get the device IP

用一个类似 iOS 下的 APP: Fing

扫描一下局域网，名为 'Espressif' 的设备即为 OpenPlug 设备

[编辑] 7.1 Prepare firmware

Get noduino-sdk：

$ git clone --recursive git://github.com/icamgo/noduino-sdk.git noduino-sdk

Generate toolchain (you need Python 2.7)：

$ cd noduino-sdk/toolchain
$ ./gen.py

Compile Open Plug firmware：

$ cd ../sketch/open-plug
$ make

The generated firmware is located in build/ dir named user1.bin annnd user2.bin

Window environment please refer to Getting Started with Noduino SDK on Windows, you can get how to setup the basic developmennt environment

[编辑] 7.2 Upload

[编辑] 7.2.1 Serial

USB2UART_GND ------> SmartNode_GPIO0
USB2UAR_GND -----> SmartNode_GND
USB2UAR_RXD -----> SmartNode_TX
USB2UAR_TXD -----> SmartNode_RX

Connect USB2UAR_VCC3.3 -----> SmartNode_VCC at last

ESP8285 will be enter upload mode, we can upload the compiled firmware through serial using following commands in Linux:

$ cd /path/to/noduino-sdk/sketch/open-plug
$ make produce ESPPORT=/dev/ttyUSB1

In windows:

$ make produce ESPPORT=COM7

COM7 is your USB2UART device

In MAC OS, maybe it's:

$ make produce ESPPORT=/dev/cu.SLAB_USBtoUART

/dev/cu.SLAB_USBtoUART is your USB2UART device

[编辑] 7.2.2 Online

Access

http://dev.noduino.org/openonoff

Login

Username: noduino
password: noduino1234

Click the "Add files", select the user1.bin and user2.bin located in /path/to/noduino-sdk/sketch/open-plug/build/

Then click "Start upload" to upload the user1.bin and user2.bin into the server temporaily

Enter Official Account, then click "Add" menu, enter "Debug" page

Select your device and the input "ota" in the data aera then click "send data"

Device will download your user1.bin or user2.bin and write it into flash when the device received the "ota" message

You will see the device online message in the Debug page when the uploading is finished
