# Fix unreachable net services V2
**Attention: This usermod compiles only for ESP8266**
This usermod-v2 modification performs a ping request to the local IP address every 60 seconds. By this procedure the net services of WLED remains accessible in some problematic WLAN environments.
The modification works with static or DHCP IP address configuration.
**Webinterface**: The number of pings and reconnects is displayed on the info page in the web interface.
_Story:_
Unfortunately, with all ESP projects where a web server or other network services are running, I have the problem that after some time the web server is no longer accessible. Now I found out that the connection is at least reestablished when a ping request is executed by the device.
With this modification, in the worst case, the network functions are not available for 60 seconds until the next ping request.
## 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.

```
## Usermod installation (advanced mode)
## API to enable/disable the PIR sensor from outside. For example from another usermod.
In this mode IR sensor will disable PIR when light ON by remote controller and enable PIR when light OFF.
The class provides the static method `PIRsensorSwitch* PIRsensorSwitch::GetInstance()` to get a pointer to the usermod object.
1. Copy the file `usermod_PIR_sensor_switch.h` to the `wled00` directory.
2. Register the usermod by adding `#include "usermod_PIR_sensor_switch.h"` in the top and `registerUsermod(new PIRsensorSwitch());` in the bottom of `usermods_list.cpp`.
3. Add to the line 237, on `wled.h` in the `wled00` directory:
To query or change the PIR sensor state the methods `bool PIRsensorEnabled()` and `void EnablePIRsensor(bool enable)` are available.
`WLED_GLOBAL bool m_PIRenabled _INIT(true); // enable PIR sensor`
### There are two options to get access to the usermod instance:
4. On `ir.cpp` in the `wled00` directory, add to the IR controller's mapping (beyond line 200):
1. Include `usermod_PIR_sensor_switch.h` **before** you include the other usermod in `usermods_list.cpp'
- To the off button:
`m_PIRenabled = true;`
or
- To the on button:
`m_PIRenabled = false;`
2. Use `#include "usermod_PIR_sensor_switch.h"` at the top of the `usermod.h` where you need it.
5. Edit line 40, on `usermod_PIR_sensor_switch.h` in the `wled00` directory:
**Example usermod.h :**
```cpp
#include "wled.h"
`\\bool m_PIRenabled = true;`
#include "usermod_PIR_sensor_switch.h"
class MyUsermod : public Usermod {
//...
void togglePIRSensor() {
if (PIRsensorSwitch::GetInstance() != nullptr) {
PIRsensorSwitch::GetInstance()->EnablePIRsensor(!PIRsensorSwitch::GetInstance()->PIRsensorEnabled());
}
}
//...
};
```
