save the value of a variable in the LM
#1
Hi,

I would like to know how I can save the value of a variable inside the memory of the LM, but that this value will never be erased.
the idea is that I keep the value of a meter variable one month (for example March), the next month (for example April) I create another variable and I keep the value of that month in that variable. Then I take the value of the first variable and I make a difference between the first and the second variable. this to make a comparison of consumption.

I've been looking for a similar example but I have not found anything.

thank you Big Grin

Hi
How do you want to display the data? If via trend then in there you have ready solution to compare the same trend with different period. If you want the value itself then fetch the data via this. http://openrb.com/docs/trends-new.htm
