Chamber Temperature Display?

I want to add a temperature sensor so I can heat my chamber to a certain temp before printing. I also want to add an exhaust fan to keep my chamber at a set temperature while printing to prevent jamming in the extruder. I found a little info on the ratos website but I can’t understand how I need to add the code to the cfg file. Also what pins I should use for the temperature sensor and the exhaust fan? I can’t seem to find any info in the discord.
