Before I'll rumble through that, I'd like to add another node to the

I
don't like the 100ms time needed there.
Sounds great, though the datasheet calls it "All Lines Off". Why choose
"clearevent" as the name?
I'll plan to use this "clearevent" node with my DS2409 driven locks. The
event
is triggered on connection of an iButton to the lock. Then one does only
have
to scan the "alarm" directory of the backbone to check for new keys.
There are some subtilties with deeper branching. OWFS kee[s trak of the last
selected path to reduce redundant path selection (you have to turn off all
sister DS2409s at each level). I'll add a flag that marks the stored path as
untrustworthy.
May I check in the change directly or should I send a patch?
Please change directly.
Kind regards
Jan
