# IotWebConf [](https://travis-ci.org/prampec/IotWebConf)
|
||||||
|
|
||||||
|
## Summary
|
||||||
|
IotWebConf is an Arduino library for ESP8266/ESP32 to provide a non-blocking standalone WiFi/AP web configuration portal.
|
||||||
|
**For ESP8266, IotWebConf requires the esp8266 board package version 2.4.2 or later!**
|
||||||
|
|
||||||
|
Please subscribe to the [discussion forum](https://groups.google.com/forum/#!forum/iotwebconf), if you want to be informed on the latest news.
|
||||||
|
|
||||||
|
## Highlights
|
||||||
|
|
||||||
|
- Manages WiFi connection settings,
|
||||||
|
- Provides a config portal user interface,
|
||||||
|
- You can extend the configuration with your own property items, that are stored automatically,
|
||||||
|
- HTML customization,
|
||||||
|
- Validation support for the configuration property items,
|
||||||
|
- User code will be notified of status changes with callback methods,
|
||||||
|
- Configuration (including your custom items) stored in the EEPROM,
|
||||||
|
- Firmware OTA update support,
|
||||||
|
- Config portal remains available even after WiFi is connected,
|
||||||
|
- Automatic "Sign in to network" pop up in your browser (captive portal),
|
||||||
|
- Non-blocking - Your custom code will not be blocked in the whole process.
|
||||||
|
- Well documented header file, and examples from simple to complex levels.
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## How it works
|
||||||
|
The idea is that the Thing will provide a web interface to allow modifying its configuration. E.g. for connecting to a local WiFi network, it needs the SSID and the password.
|
||||||
|
|
||||||
|
When no WiFi is configured, or the configured network is unavailable it creates its own AP (access point), and lets clients connect to it directly to make the configuration.
|
||||||
|
|
||||||
|
Furthermore there is a button (or let's say a Pin), that when pressed on startup will cause a default password to be used instead of the configured (forgotten) one.
|
||||||
|
You can find the default password in the sources. :)
|
||||||
|
|
||||||
|
IotWebConf saves configuration in the "EEPROM". You can extend the config portal with your custom configuration items. Those items will be also maintained by IotWebConf.
|
||||||
|
|
||||||
|
## Use cases
|
||||||
|
1. **You turn on your IoT the first time** - It turns into AP (access point) mode, and waits for you on the 192.168.4.1 address with a web interface to set up your local network (and other configurations). For the first time a default password is used when you connect to the AP. When you connect to the AP, your device will likely automatically pop up the portal page. (We call this a Captive Portal.) When configuration is done, you must leave the AP. The device detects that no one is connected, and continues with normal operation.
|
||||||
|
1. **WiFi configuration is changed, e.g. the Thing is moved to another location** - When the Thing cannot connect to the configured WiFi, it falls back to AP mode, and waits for you to change the network configuration. When no configuration was made, then it keeps trying to connect with the already configured settings. The Thing will not switch off the AP while anyone is connected to it, so you must leave the AP when finished with the configuration.
|
||||||
|
1. **You want to connect to the AP, but have forgotten the configured AP WiFi password you set up previously** - Connect the appropriate pin on the Arduino to ground with a push button. Holding the button pressed while powering up the device causes the Thing to start the AP mode with the default password. (See Case 1. The pin is configured in the code.)
|
||||||
|
1. **You want to change the configuration before the Thing connects to the Internet** - Fine! The Thing always starts up in AP mode and provides you a time frame to connect to it and make any modification to the configuration. Any time one is connected to the AP (provided by the device) the AP will stay on until the connection is closed. So take your time for the changes, the Thing will wait for you while you are connected to it.
|
||||||
|
1. **You want to change the configuration at runtime** - No problem. IotWebConf keeps the config portal up and running even after the WiFi connection is finished. In this scenario you must enter username "admin" and password (already configured) to enter the config portal. Note, that the password provided for the authentication is not hidden from devices connected to the same WiFi network. You might want to force rebooting of the Thing to apply your changes.
|
||||||
|
|
||||||
|
## IotWebConf vs. WiFiManager
|
||||||
|
tzapu's WiFiManager is a great library. The features of IotWebConf may appear very similar to WiFiManager. However, IotWebConf tries to be different.
|
||||||
|
- WiFiManager does not manages your custom properties. IotWebConf stores your configuration in "EEPROM".
|
||||||
|
- WiFiManager does not do validation. IotWebConf allow you to validate your property changes made in the config portal.
|
||||||
|
- With WiFiManager you cannot use both startup and on-demand configuration. With IotWebConf the config portal remains available via the connected local WiFi.
|
||||||
|
- WiFiManager provides list of available networks and also an information page, while these features are cool, IotWebConf tries to keep the code simple. So these features are not (yet) provided by IotWebConf.
|
||||||
|
- IotWebConf is fitted for more advanced users. You can keep control of the web server setup, configuration item input field behavior, and validation.
|
||||||
|
|
||||||
|
## Security aspects
|
||||||
|
- The initial system password must be modified by the user, so there is no build-in password.
|
||||||
|
- When connecting in AP mode, the WiFi provides an encryption layer, so all you communication here is known to be safe.
|
||||||
|
- When connecting through a WiFi router (WiFi mode), the Thing will ask for authentication when someone requests the config portal. This is required as the Thing will be visible for all devices sharing the same network. But be warned by the following note...
|
||||||
|
- NOTE: **When connecting through a WiFi router (WiFi mode), your communication is not hidden from devices connecting to the same network.** So either: Do not allow ambiguous devices connecting to your WiFi router, or configure your Thing only in AP mode!
|
||||||
|
- However IotWebConf has a detailed debug output, passwords are not shown in this log by default. You have
|
||||||
|
to enable password visibility manually in the IotWebConf.h with the IOTWEBCONF_DEBUG_PWD_TO_SERIAL
|
||||||
|
if it is needed.
|
||||||
|
|
||||||
|
## Compatibility
|
||||||
|
IotWebConf is primary built for ESP8266. But meanwhile it was discovered, that the code can be adopted
|
||||||
|
to ESP32. There are two major problems.
|
||||||
|
- ESP8266 uses specific naming for it's classes (e.g. ESP8266WebServer). However ESP32 uses a more generic naming (e.g. WebServer). The idea here is to use the generic naming hoping that ESP8266 will adopt these "standards" sooner or later.
|
||||||
|
- ESP32 does not provides an HTTPUpdateServer implementation. So in this project we have implemented one. Whenever ESP32 provides an official HTTPUpdateServer, this local implementation will be removed.
|
||||||
|
|
||||||
|
## TODO / Feature requests
|
||||||
|
- We might want to add a "verify password" field.
|
||||||
|
- Possibility to organize blocks of config items to lists. (E.g. provide more SSIDs with passwords as a connection option.)
|
||||||
|
- Option the configure multiply WiFi connections. Try next when the last used one is just not available.
|
||||||
|
|
||||||
|
## Known issues
|
||||||
|
- It is reported, that there might be unstable working with different lwIP variants. If you experiment serious problems, try to select another lwIP variant for your board in the Tools menu! (Tested with "v2 Lower Memory" version.)
|
||||||
|
|
||||||
|
## Credits
|
||||||
|
Although IotWebConf started without being influenced by any other solutions, in the final code you can find some segments borrowed from the WiFiManager library.

|
* Description:
|
||||||
|
* All IotWebConf specific aspects of this example are described in
|
||||||
|
* previous examples, so please get familiar with IotWebConf before
|
||||||
|
* starting this example. So nothing new will be explained here,
|
||||||
|
* but a complete demo application will be build.
|
||||||
|
* It is also expected from the reader to have a basic knowledge over
|
||||||
|
* MQTT to understand this code.
|
||||||
|
*
|
||||||
|
* This example starts an MQTT client with the configured
|
||||||
|
* connection settings.
|
||||||
|
* Will post the status changes of the D2 pin in channel "/test/status".
|
||||||
|
* Receives messages appears in channel "/test/action", and writes them to serial.
|
||||||
|
* This example also provides the firmware update option.
|
||||||
|
* (See previous examples for more details!)
|
||||||
|
*
|

* https://github.com/256dpi/arduino-mqtt
|
||||||
|
*
|
||||||
|
* Hardware setup for this example:
|
||||||
|
* - An LED is attached to LED_BUILTIN pin with setup On=LOW.
|
||||||
|
* - [Optional] A push button is attached to pin D2, the other leg of the
|
||||||
|
* button should be attached to GND.

* It is also expected from the reader to have a basic knowledge over

* MQTT to understand this code.
|
||||||
|
*
|
||||||
|
* This example starts an MQTT client with the configured
|
||||||
|
* connection settings.
|
||||||
|
* Will receives messages appears in channel "/devices/[thingName]/action"
|
||||||
|
* with payload ON/OFF, and reports current state in channel
|
||||||
|
* "/devices/[thingName]/status" (ON/OFF). Where the thingName can be
|
||||||
|
* configured in the portal. A relay will be switched on/off
|
||||||
|
* corresponding to the received action. The relay can be also controlled
|
||||||
|
* by the push button.
|
||||||
|
* The thing will delay actions arriving within 7 seconds.
|
||||||
|
*
|
||||||
|
* This example also provides the firmware update option.
|
||||||
|
* (See previous examples for more details!)
|
||||||
|
*
|
||||||
|
* Software setup for this example:
|
||||||
|
* This example utilizes Joel Gaehwiler's MQTT library.
|
||||||
|
* https://github.com/256dpi/arduino-mqtt
|
||||||
|
*
|
||||||
|
* Hardware setup for this example:
|
||||||
|
* - A Relay is attached to the D5 pin (On=HIGH). Note on relay pin!
|
||||||
|
* - An LED is attached to LED_BUILTIN pin with setup On=LOW.
|
||||||
|
* - A push button is attached to pin D2, the other leg of the
|
||||||
|
* button should be attached to GND.
|
||||||
|
*
|
||||||
|
* Note on relay pin
|
||||||
|
* Some people might want to use Wemos Relay Shield to test this example.
|
||||||
|
* Now Wemos Relay Shield connects the relay to pin D1.
|
||||||
|
* However, when using D1 as output, Serial communication will be blocked.
|
||||||
|
* So you will either keep on using D1 and miss the Serial monitor
|
||||||
|
* feedback, or connect your relay to another digital pin (e.g. D5).
|
||||||
|
* (You can modify your Wemos Relay Shield for that, as I show it in this
|
||||||
|
* video: https://youtu.be/GykA_7QmoXE)

|
* Description:
|

|
* All IotWebConf specific aspects of this example are described in
|
||||||
|
* previous examples, so please get familiar with IotWebConf before
|
||||||
|
* starting this example. So nothing new will be explained here,
|
||||||
|
* but a complete demo application will be built.
|
||||||
|
* It is also expected from the reader to have a basic knowledge over
|
||||||
|
* HTML to understand this code.
|
||||||
|
*
|
||||||
|
* This example stets up a web page, where switch action can take place.
|
||||||
|
* The repay can be also altered with the push button.
|
||||||
|
* The thing will delay actions arriving within 10 seconds.
|
||||||
|
*
|
||||||
|
* This example also provides the firmware update option.
|
||||||
|
* (See previous examples for more details!)
|
||||||
|
*
|
||||||
|
* Hardware setup for this example:
|
||||||
|
* - A Relay is attached to the D1 pin (On=HIGH)
|
||||||
|
* - An LED is attached to LED_BUILTIN pin with setup On=LOW.
|
||||||
|
* - A push button is attached to pin D2, the other leg of the
|
||||||
|
* button should be attached to GND.
