as always, I do not know whether it is the best solution, but I have done so
.
In the infinite main loop, I ask to owserver the list of present objects,
and store it in an array: there can be connected just one iButton at a time.
In the array will be some objects always present (master bus, switch, etc.)
that I can drop from array.
If the array is empty, no iButton connected.
Other way, I can check the object to see if it is an authorized one.
I'd like to share my source, but I need a little time, at least to
translate comments and variable_names! ;)
