LM5 and KNX integration - how should you work with programming

[dreamcatcher]

Virtual objects are outside KNX range so they cannot be used in ETS. In most cases you can disable "write to bus" option for normal objects and use grp.update instead of grp.write in scripts. This won't send values to KNX/TP bus and will reduce bus load.

Thanks for info. Is it possible to tell when you should start practicising segregation of objects from the KNX/TP bus? I.e. how big a project can be before any practical implications. And what will be the first symptoms of a problem?
