Hello dear community
I have a question wanted to ask what the basic function of the connector is?
I know that it has something to do with websocket, that the standard port is used, and that a tunnel is set up in reverse. is it a standard procedure? is there a representation?
I would like to adapt the function.
If anyone could help me then I would be incredibly grateful
It is not exactely websocket, openhabcloud end uses npm/js hence it has some socket.io stuff which can downgrade connection to other mechanis than websocket. In practice it is websocket.
Role of connector is quite basic - it opens connection to remote server and then waits for calls/commands on opened channel. These commands coming from server are usually forwarded HTTP calls which are used to instruct embedded http client to call localhost:8080. Answers are being sent back to server using same channel. By this way your OH is accessible through cloud server.
There is second form of communication - a event stream published by OH to myopenhab with item states (AFAIR) and notifications which are then dispatched by myopenhab cloud.
Thank you very much for the quick answer, that helped me
