Can someone help me please? i have setup a little webserver on esp wich switches a relays like 192.168.2.221:84/relays-on or 192.168.2.221:84/relays-off. this works on a browser. Now there is another webserver running on an arduino uno with ethernet, this one must call the esp to switch relays on/off. HOW is the syntax for such a webcall please?
