# Fix unreachable net services V2

**Attention: This usermod compiles only for ESP8266**

This usermod-v2 modification performs a ping request to a local IP address every 60 seconds. This ensures WLED net services remain accessible in some problematic WLAN environments.

The modification works with static or DHCP IP address configuration.

_Story:_

Unfortunately, with many ESP projects where a web server or other network services are running, after some time, the connecton to the web server is lost.
The connection can be reestablished with a ping request from the device.

With this modification, in the worst case, the network functions are not available until the next ping request. (60 seconds)

## Webinterface

The number of pings and reconnects is displayed on the info page in the web interface.
The ping delay can be changed. Changes persist after a reboot.

## JSON API

The usermod supports the following state changes:

| JSON key    | Value range      | Description                     |
|-------------|------------------|---------------------------------|
| PingDelayMs | 5000 to 18000000 | Deactivdate/activate the sensor |

 Changes also persist after a reboot.

## Installation

1. Copy the file `usermod_Fix_unreachable_netservices.h` to the `wled00` directory.
2. Register the usermod by adding `#include "usermod_Fix_unreachable_netservices.h"` in the top and `registerUsermod(new FixUnreachableNetServices());` in the bottom of `usermods_list.cpp`.

Example **usermods_list.cpp**:

```cpp
#include "wled.h"
/*
 * Register your v2 usermods here!
 *   (for v1 usermods using just usermod.cpp, you can ignore this file)
 */

/*
 * Add/uncomment your usermod filename here (and once more below)
 * || || ||
 * \/ \/ \/
 */
//#include "usermod_v2_example.h"
//#include "usermod_temperature.h"
//#include "usermod_v2_empty.h"
#include  "usermod_Fix_unreachable_netservices.h"

void registerUsermods()
{
  /*
   * Add your usermod class name here
   * || || ||
   * \/ \/ \/
   */
  //usermods.add(new MyExampleUsermod());
  //usermods.add(new UsermodTemperature());
  //usermods.add(new UsermodRenameMe());
  usermods.add(new FixUnreachableNetServices());

}
```

Hopefully I can help someone with that - @gegu
