wtf is temp-in-out?

Temp-IN-OUT is a small personal home automation project for tracking temperature and humidity both outside and inside a house. The author has one SHT45 sensor placed outside and another placed inside, both wired to a Raspberry Pi 3. The idea is simple: by comparing the outside and inside readings, the author can tell when it makes sense to open all the windows during summer to cool the house down naturally instead of relying only on judgment or guessing. The Raspberry Pi runs headless, meaning it operates without a monitor or keyboard attached, and is controlled remotely from the author's Linux PC. A Python script running on the Pi reads the sensors and writes each measurement as a new line into an Excel spreadsheet file, saved directly on the Pi. A second Python script, called GRAPHING.py, runs separately on the Linux PC rather than on the Pi itself. Every five minutes, this script reads the most recent line from that spreadsheet file over the network and uses it to build a graph, giving the author a visual way to watch how the indoor and outdoor temperatures compare over time. The project is very small in scope: two Python scripts and a shared spreadsheet file acting as the data store between them. There is no mention of a formal installation process, configuration file, or dependency list in the README, so setting it up would likely mean adapting the sensor wiring and file paths to match your own Raspberry Pi and PC setup. This is a hobby project built to solve one specific problem for one household rather than a general purpose tool meant for wide reuse.
