@thomas at the moment, my priority is getting a "blink test" up and running. In other words, I'm prioritizing getting everything talking to everything.
Sensors -> Raspberry Pi
Raspberry Pi <-> Cloud
Raspberry Pi <-> UI
UI <-> Cloud
After that, my plan is to start working on a dashboard UI that can both read and write to the Food Computer (similar in concept to what you've posted above). We've actually got a JS framework for this already, along with design files for how those sensor readings should look. Fun stuff!
