The inability for Apex to tell me when my dosing containers are empty drives me insane, obviously trying to push you in the direction of the outrageously expensive DDR. Since the DOS is smart enough to measure the fluid it's dosing throughout the day, is there a way to program a virtual outlet to count the amount of daily fluid dosed at the end of each day and send me an alert when my dosing container is getting low? In terms of a normal programming language this would be simple, but not sure if it's possible to store a peak value which can be added to later in a virtual outlet. Thanks for the help!
