    I was getting very frustrated that the cbus command line interface that seems to be intermittently working and not working, but if I use the toolkit to turn lights on, it always seems to work. Like

    on !b1

    Works, then doesn't work. With some observation of the logs and trying things, I noticed that this always works, even when the above doesn't:

    on !b1 force
    off !b1 force

    what is this "force" thing that causes it to work, when it otherwise doesn't? And why do I need to use it to make things work?

    Hi countach,

    C-Gate maintains a model that keeps track of whether a network is connected, its error state and what units and groups there are. By default the application commands (such as ON) are validated against this model before they're sent.

    The C-Gate Manual explains:

    Essentially it just instructs C-Gate to ignore the model and push it onto the physical wire.

    force

    So... what does it mean when I have to use force to make it happen? Does it mean my physical network is dodgy?

    Not necessarily - C-Gate may not have synced the network yet. The syncing process can take several minutes. The "force" parameter allows a control system that already knows the addresses to execute level changes without waiting on the sync to finish.
