And here is the details about the priority:
/*************************************************************** * The lcdwarn messages can be one of 5 levels: * 0 - warning - makes the Alert LED glow yellow * 1 - error - makes the Alert LED blink yellow * 2 - alert - makes the Alert LED glow red * 3 - critical - makes the Alert LED glow red * 4 - emergency - makes the Alert LED blink red * 5 - info - leave the LED off * * You may use `lcdwarn` or `clearlcd_*` command line programs to add * or clear warnings from the LCD/LED. * It is possible that you will have some warnings and some alerts, so * when you clear the error, the LED will stop being red and turn * yellow. You will have to clear that error seperately. ***************************************************************/
I hope this information will be useful to someone else in the future.
