I'm new to JavaScript and webpage design so I'm not sure how to ask this question. Using an ESP32 as a webserver, I have created a webpage that contains a toggle switch to control a mode of the ESP32. I wish to control this mode on multiple ESP32's from a separate webpage, basically a master/slave arrangement. Hit a button on the master webpage and change the mode on all the ESP32's, which are on the same LAN. What would be the best approach to doing this? Apologies if this question is too vague or opinion based.
