Temperature And Humidity

A few month ago, i stared collecting my appartement temperature and humidity data.
I saved everything in order to try to predict home temperature with outside temperature forecast.
There are some data missing and some interferences.
I live in a 73 square meters flat with 3 roomates.
We can be up to 6 in the appartement if people are coming to visit us.
We used a portable AC some days during the summer.
We tend to open windows at night during summer.
We have 2 gaming pc in the 'bureau' so temperatures are influenced by that when we are gaming.
