Nice board also. The /RST I think is the PowerPC reset input. The power on reset. I don’t think that the CPU or anything else on the main board drives it, so assume it’s a main board input on the 100 pin connector. If so then you could drive it from your ESP Wemo - to reset the scope. But why would you?
The web-server that i used was a direct copy of what was on this forum elsewhere, from Russia. Arduino, ESP32 DevKit-c. Stumbled initially by not having the file system for the index.html and java script, plus some other plugins, but could google and github download my way through all the compile/load error messages so that it worked eventually.
Still due: make the web server connect as client to my home WiFi, so my SSID from my network, instead of this ESP32 DevKit acting as independent WiFi router with its own SSID.
