Tiling screened in porch

I want to tile the floor in my planned screened in porch. Porch will be about 32" off ground. Planning on t&g osb subfloor, topped with cement board (set in thinset and screwed down) followed by Ditramat then tile. Will apply waterproofing over cement board (red guard or hydroban).
Is this overkill?

Ditra or Cement Board, not both. Redgard or other roll on waterproofing is not needed with Ditra.

Not the pro here but wouldn't that be considered a damp area under the porch?
