Hmm. Seems like fish-brain still hasn't comprehended how Z-Wave works. The
Z-Wave RF signal hops from one node to another SEQUENTIALLY until it has
used up its 4 hops. The Z-Wave RF signal is not ubiquitous. It goes from
node A to node B, then it goes from node B to node C, then it goes from node
C to node D, and then it goes from node D to node E. It cannot go to another
node after E as it has used up all its hops. Each sequential hop takes about
60mS or 250mS for A>B>C>D>E. Sending an ACK back from node E to node A takes
the same number of hops and time. This is the best case scenario - things
deteriorate if there are any problems along the way, like Bobby Green's
stealthy spouse blocking a signal sequence.

Lutron's RadioRA has repeaters every 25' which repeat in real-time. That RF
signal IS ubiquitous.

The Insteon signal is semi-sequential and has a limited number of hops but
it tends to become more ubiquitous as more nodes receive and repeat the
signal (simultaneously) but I suspect this is all beyond the comprehension
of a tiny fish-brain.

Fish-brain really should put his shovel away.
