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;
return result;

This should calculate the exact timestamp when the burner switches ON.

Hi Arne,

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.
