The idea came across on demand of my building automation projects. I use a lots of EasyIO FG32+ controllers and they are on my top list as they are the only controllers i have came along that you can fully customize and you know what? It has HTML web server for custom data display and many more… (Will post another story line about these “FG beasts” later ). Unfortunate it does not have alarm console that users could centralized manage ongoing alarms on the building HVAC systems. As I mentioned it is so flexible so some html, javascript, sqlite, and php and you have new feature as some top modern BMS systems does in the market under only DDC controller bonet.
And yes AlarmDB is free to use and sell. Opensource under MIT!
