If my understanding is correct each instance needs to create a
heartbeat> but can issue messages of any schema it likes.This is
correct, yes> This would work well with having each zone as a particular
instance with> multiple device types hanging off each zone.
The problem comes when you> want to attach two temperature devices
within a particular zone. You then> need to distinguish
between the two so need to set the instance at the> device level rather
than the zone level.This was where the "device=" tag will be
used.In essence, this is the same situation as an X-10 "bus" with
multiplemodules on it..A gateway would generate a series of status
messages, of the formdevice=sensor1temp=device=sensor2temp=Each from the
instance of the 1-wire gateway
, just as x10 trigger messagesoriginate from a CM12 gateway app with a
device=(module id)> There may be others ways to set things up but I
think we need to pull> everyone's ideas of how they think it might be
implemented together up> front to flush out all the options.
Therefore any interested party now is> the time to put forward your
view.indeed. I think the version I have outlined is the one currently
favoured byMyself, John and Tony, from the conversations we have had over
the last fewdays, but now is certainly the time to resolve these
matters.Ian.</TT><TT>xPL Links: <A href="http://www.xplproject.org.uk";>http://www.xplproject.org.uk</A>
