After a few mis-starts, I’ve built a simple “kegerator monitor” using the Spark Core. Basically, I weigh the keg every 30 seconds or so using the MeasSpec FX1901 load cell and publish those values. From there I can check a little web-app on my phone so I can always know the level of my kegerator. I’m working on some analytic math to get average ounces per hour/day consumed, how much the flow rate spikes at halftime versus in the middle of a big play, or beers per month consumed. ‘Estimated time until empty’ I really need to get working…
Here’s the monitor running live: http://www.4drillsbrewery.com/kegmon/

Any suggestions? Have I wired everything up correctly? Any additions or other thoughts I should add?
