As an update I have gotten the raspberry pi to be able to trigger relays in tests of just how the pi communicates with the relays both via the command line and via a python script. Today I just finished up reading three temp probes in parallel. Making progress. Just need to start working on the programming logic of probes to trigger the relays now. Shouldnt be that long to get at least a 1 probe 1 relay system working. Alerts and emails are on phase 3.
