ESP8266/NodeMCU Gateway LEDs

[LastSamurai]

Hi, I am going to build a new gateway using a nodemcu and wanted to add leds for rx/tx/error too that build. The standard sketch only seems to use the integrated led though. Which pins on the ESP can be used for that? Would there be 2 other digital pins left for some 433Mhz sender/receiver I also plan to add?

Its been some time since I worked with the ESP8266 and the pins have so many different assignments, so I am unsure which can be used.

Any unused digital pins will do, just define them in sketch

@LastSamurai many of the esp8266 pins are special. I have run into a lot of trouble when using the ones that aren't marked as "safe" to use in Kolban's book. Some more information:
