Help with mqtt switch config

Configuration
1

Hi. I’ve bee having issue with my config file.

I currently have a Nodemcu using ESPEASY with a led connected to GPIO 14. I can run the web command from my browser http://192.168.0.31/control?cmd=GPIO,14,1Which turns the led on.

I need help setting up a switch in HA. When i connect my nodemcu and view the comm log it says its connected to my brooker, which is my RPI running HA. its says connected /mcu/#. mcu being the name of my nodemcu.

What would be command and state information be? This is the last issue i need to overcome.
After this i want HA to know if that switch is on or off. I am now sure how i would go about this.

Thanks!!!
