+## Classes
+
+For the websockets we are going to use 2 classes. One for the nodes and one for the websites. The nodes are going to send data to the website and have multiple variables like temperature, humidity, eCO2, TVOC and sound. The website is going to send data to the nodes like names and settings. For this they have to use a userName and password.
