Re: Re: CBUS & Comfort Questions

[Kevin Hawkins <lists@xxxxxxxxxxxxxxxxx>]

C-Bus actually send a single ramp over 4 seconds command to 1 or 255
when dimmer switches are pressed and held.  This will result in a 1 or
255 appearing in the counter as soon as you hold the button. When you
release the button then the current level within that ramp is calculated
and the old ramp command is superseded by a direct set to that level
which will result in another update to the counter of the desired dim
level.  For X10 to appear at all useful with this operation you will
need the equivalent X10 0-100% Dim rate to be 4 seconds too . At the end
of a 'hold keypress' the X10 level will likely jump when released too.
All in all I suspect the press to hold dim operation to be pretty hit
and miss - but on. off , preset dims and scenes could work nicely.

Also I should have mentioned another software only  route for C-Bus to
X10 which uses xPL...

C-Bus <> CGate <> xPL <>xPLHAL<> xPL X10 conduit
