Booted up the raspberry pi again and had plenty of updates. I started the python script to log the data on a time interval. Fermenting usually takes 2-4 weeks so it will be logging for a relatively long time. I just started by having it record numbers since I didn't have sensors hooked up but I download a program called 'Screens'. There is a nice tutorial/overview in this link. With this I can have the program run in the background after I disconnect via SSH and I can reconnect later to download the data file or reattach to the 'screen' that is running the program to view the current temperatures. I'm working on incorporating it into a controlled fermentor that logs and maintains a set temperature. More to come...
Here you can see the data file recording with time stamps, temperature and lux (numbers made up). It also displays it in the terminal as it records.
