Set Value and Time from Meta Data Source
Hi, I have added a new protocol to mango (openv4j) for Viessmann heating systems (http://www.viessmann.com and (the reverse engeneering page in german) http://openv.wikispaces.com/). - One If its stable source code will follow.
so reading one value take 3 sec ... to get the timepoint of burner starts I get the operating time for the burner.... So I thougth getting the change and then calculate the difference from the last value gives the timepoint of start/end very precicely.
So is ther a way to archive this?? - Set value and timepoint for that value?

I believe this is upcoming in the next mango version, see this thread: http://mango.serotoninsoftware.com/forum/posts/list/224.page towards the end
No I think not exactly what I want.
I want something like:
var isCurrentlyON = p11.value > p11.valueBeforeThis.value;
result.value = isCurrentlyON;
result.time = p11.time - (p11.value - p11.valueBeforeThis.value) * 1000;
This should calculate the exact timestamp when the burner switches ON.
Assuming your script calculations are correct, all you would have to change (come the next version) is this:
TIMESTAMP = p11.time - (p11.value - p11.valueBeforeThis.value) * 1000;
The setting of this global variable will be detected after the script runs and will be used as the timestamp of the sample.
