I want help to select the best way to achieve best result for my project.
I want to build several nodes( about 8 - 16 ) using ESP8266 with few sensors placed on one network( no internet access), which will periodically( every 500ms) sending data to one server for further processing.
I can use also ethernet network and Wiznet W5500 shields.
As I know there is maximum 5 clients( websocket ) at same time can be connected to ESP8266.
Can someone help what architecture is the best way?
sorry I am newbie here...
