 **Features:**
 - It can run continuously as a system service or only in an open web interface.
 - Checking the availability of a host using ping or by connecting via TCP to a specified port.
- - Execution of custom shell scripts when connecting and disconnecting the Internet.
 - LED indication of Internet availability.
 ![](https://github.com/gSpotx2f/luci-app-internet-detector/blob/master/screenshots/internet-led.jpg)
+ - Performing actions when connecting and disconnecting the Internet (Restarting network, modem or device. Executing custom shell scripts).
+ - Sending email notification when Internet access is restored.
 - The daemon is written entirely in Lua using the nixio library.
