[dss-developer] groups over zones, function id?

[Dominik Wieser]

Hello,
I have some questions and would be glad if anybody could answer them.

- Is there a some kind of group that can include devices of different
zones. As far as I understand groups can only include devices of the
same zone and of the same standard or user group.
I would think groups that can hold devices of different zones also
could be very useful. So you could make a group containing all
jalousies of the southside of the house for example. Is there such a
possiblity? I thought about doing this with the property system. But
the variables i created are always gone, as soon as the server gets
restarted. How can I save the properties.

On the wiki i found the following sentence:
Each Device has (beside some other Information) a function-ID, which
defines what behavior is called thought the dSM, when a event has been
issued by that device (a light device has function-id 0x1***, so when
a button-press-event comes from that device, the dSM know, that a
scenecall for light must be issued)
What is exactly is the function id? How can I get this id over the
api? And how can I know which device it is, with the help of the
function id? is there a kind of table?
I also don't really understand the concept of the user groups.

Could anybody explain please?

Thanks a lot and have a nice evening
