First night monitoring temperature

Last night, I configured RRD graphs to record the changes of temperature.

Before bed I set the aircon on pretty much full blast. Before going to sleep it was readying at around 26.7 C.

Now as you can see with the graph, the temperature changes way too slowly. Too gradual. This will prove troublesome when calibrating as I get deeper into my next project. (I was hoping for more obvious changes).

The sudden reversal at around 4am is when my wife woke up and reduced the intensity of the air conditioning. This is certainly an area of focus in my project. (adjust it before she wakes up to do it herself).
