setting value of object without triggering script or writing on bus

[npinguin]

Do you mean you want to change internal object value in LM? Can you give some detail on why do you need this?

Indeed i have created a Gateway for Yamaha devices where the commands to the Yamaha device get triggered through  Objects tagged with Yamaha which Works perfectly,

But if I sync the device state through a deamon, which is needed when the user uses his remote for instance then I end up in a loop by triggering the same command again to the Yamaha

If I do not do the status update on that object but another specific status object I cannot use check write anymore.
