Measure Wi-Fi Signal Levels with the ESP8266 and ThingSpeak | ESP8266 Wi-Fi Module | Forum

I created a tutorial that uses the ESP8266 (NodeMCU version from Amazon) and sends data to ThingSpeak. I tried to document all of the steps to get the Arduino IDE configured and use it to program the ESP8266.

Here's a link to my tutorial: http://nothans.com/measure-wi-fi-signal-levels-with-the-esp8266-and-thingspeak
