I've been writing a small perl script to parse my 1-wire network giving just
the immediately useful values back.
One thing i have noticed is that the couplers are showing both branches are
live when i read them (cached or un-cached values), which the man pages say
is not allowed.
*"Is the branch ( 0=main or **1=aux ) currently connected to the master bus?
Value returned is 1 (yes) or 0 (no). The **DS2409 should not allow both to
be on simultaneously. "
*
Any ideas on why this is happening please?
