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
