In the OpenHAB Documentation about SCALE Transformation Service I can read about the capabillity to format the output of Scale:
At last, Scale transform can take care of formatting an output with this entry :
format=%label% (%value%) !
%label%will be replaced by transformed value and
%value%is the numeric value presented
but nowhere I can find how to implement this feature an no examples.
Can someone give me an example (code) how to use this feature?
