Hi Guy's,
I can get the arduino-webthings example sketch LED to work, but not the LED Lamp on my NodeMCu?
Could this be a result of using the ESP8266 library (2.5.2 on old mac)?
I'm not brilliant at coding, but tried a few thing and got no success.
Can someone give me some pointers in the right direction?
