detect increase or decrease

[bubaleta]

Hello,

I’m trying to detect is temperature is increasing or decreasing.
Now I’m storing the value in a variable container and checking with an schedule with the new value.

Is there a way of doing this directly with PLEG?

It would be nice to check only when the value changed and not having to use external storage.

Here’s what I have so far:

Device properties:
lastFloorTemp VariableContainer Variable4 20.3 2014-06-16 11:51:34.334 2014-06-16 11:47:41.575
tempTrend VariableContainer Variable2 TEMPUP 2014-06-16 11:27:55.376 2014-06-16 11:12:26.680

T_Suelo Temp Suelo - S3 CurrentTemperature 20.3 2014-06-16 11:51:34.199 2014-06-16 11:27:55.205

Conditions:

Actions:
updateFloorTemp VariableContainer SetVariable4 newVariable4={(T_Suelo)}

any way to simplify it?
