Hey Rony,
Thank you so so much!
I was stuck on getting some response while using the analogue inputs 
I just tested 2 and while they are next to each other, they output totally different results. I also let them settle for about 15 minutes before copying the results you see below.
Read sensor 1: OK
Humidity1 (%): 37.00
Temperature1 (oC): 22.00
Read sensor 2: OK
Humidity2 (%): 33.000
Temperature2 (oC): 21.000
Humidity is off by 4% and Temperature by 1oC. 
It says there on the wiki page that:

…but reality hit me pretty hard
