 # Internet detector for OpenWrt.
-Checking Internet availability.
+Internet-detector is an application for checking the availability of the Internet. Performs periodic connections to a known public host (8.8.8.8, 1.1.1.1) and determines the actual Internet availability.

-OpenWrt >= 19.07.
+**OpenWrt** >= 19.07.

-Dependences: lua, luci-lib-nixio, libuci-lua
+**Dependences:** lua, luci-lib-nixio, libuci-lua.
+
+**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)
+ - The daemon is written entirely in Lua using the nixio library.
