Something CAN be developed (which has been said already). All it takes is some redneck ingenuity and money. Plenty of folks with that. @Timber Hole; you don't need audio. You need a "heartbeat" monitor to occasionally sense if the plug is still firing (your app would have a heartbeat of "green" or "red"). You'd save a lot of data that way. My genset has an auto choke for electric start, and a push-button choke for manual start. If I were willing to put in the money and effort, my genset could do what we are discussing, but I'd have to be willing to buy/create a board to do those things I want it to do, and wire it all up. I'd also have to buy a data plan from a cellular company, and add a 4G (or 3G if I wanted to save a small amount of money) TX/RX'er to that board. Then you gotta keep this board weatherproof, etc. It'd get expensive quick, but yes, it could absolutely be done. Now, if ya wanted to get fancy, you'd need to add a fuel gauge to your app.
