+# Audio2 Cabin Light System by lbsfilm
+
+
+This is a simple system of lights for the phone system of Audio 2
+
+There is a controller and 4 clients, all built into the light cylinders
+
+## Software 
+
+The controller is running EspAsyncWebserver and the clients run a websocket client library.
+There is no kind of encryption (HTTP Basic Auth can be enabeled in the code though)
+
+## Hardware
+
+All Boards are built uisng the ESP32 POE Board (non isolated) by OLIMEX
+
+### Pinings
+
+Every Board is connected to the Lamp by a single GPO, The power has to be taken from the 48Volts of the POE input and be regulated to 12V(?) for the Lamp
