Temp-IN/OUT my house
I have one temperature/humidity sensor outside my house and one inside, connected to a Raspberry Pi3, I use it to know when should open all windows at my house in the summer. I use SHT45 sensors, run the pi headless from my linux PC, the code is in python, and writes to one .xlsx file on the pi. I have a Python script on the PC to read the last line of that file, every 5 minutes and produce the graph.
GRAPHING.py is to be runned on the linux PC, it reads the xlsx file on the pi and produces the graph
