ESP8266 - Wemos D1 Mini - Arduino Code - Bare-bones code, verified working

This is excellent reference code for sending data to Radmon, and was excellent for someone like me who isn't as proficient with the software side of development as the hardware.
It works on ESP32 with zero modification. I'd like to point out that the return and newline placeholders near the end of the updateRadmon() method mustn't be removed, they are essential for the HTTP request. I really was wondering what was going on there! clientGet.println("Connection: close\r\n\r\n");


For other newbees, if it isn't clear exactly how the website accepts readings, pay attention to the updateRadmon() method above that uses HTTP GET to send the data to the server. There really should be an article about it for absolute beginners, sorry if there is and I've missed it.

If HTTP GET is not familiar to you start here https://www.w3schools.com/tags/ref_httpmethods.asp (I promise it's simple.)
Despite the name, GET and POST can both be used to send data to a server.
