Creating an alert system for rapidly changing data? in Application Design Posted March 8, 2016 None of that makes any sense. Are you in the right thread? Actually, it made some sense to me in a way. Having various options for alerting is a good idea (e.g. user can pick to be alerted on Kp = 7, or if some value goes over a threshold. I'm still nutting out some other stuff, so I'll give proper thought to it when I get a moment. And I did think of a "live" service where people would pay a subscription fee that would allow me, or a team of people, to hit a button when an aurora is detected on a webcam and / or "the gauges" look promising, but that's a bit out there, and probably something I'd look at if things took off..
