Next dirty Question:
in my humple opinion ... the totalizer / PE / ACE has a couple of flaws... especally when i comes into the direction of
A) recalulation (controlled by users not piadmins..)
B) what happens if the interface is disconnected for a couple of hours,
C) what happens if pi server is down,
Has someone created an alternative engine to cover this questions?
As an example:
We have a couple of easy calculations (avg,min, max, totals...) which are done in an external dot.net application where the configuration is done in af. (in principal it summarize values and send it via textfiles to a overlying system and also via ufl back into the pi.) The goal is to manage approx 7000 calc.
the solutions for my on the top descriped problems are:
A) recalculation (the user can (based on af - rights) the date/time of the last calculation set back into the past ... and the "logic" picks up. the same for if the pi server is down..
B) if the interface is disconnected the data have 5 hours time to come back, otherwise the timeframe is ignored...
C) same as A)
My Question to myself is should the users create calc / total in PE and Totalziers or should the use our logic...
My Question to you,.. has anyone done something similarly?
