Hi, thanks for reply .... previously i using udp to communicate with production machine... it works both way from unity to watchout and watch out to unity... now i have 3 display computer , and i wish to skip the production machine .. that why i choose to use watchnet to remote control ...However, your application can communicate directly with the cluster in lieu of WATCHNET using the standard cluster control commands. It is mean that i need point my unity to those ip of the three machines? would it be a way for us to use websocket to trigger the function button click that we set in the WATCHNET?
