RE: Re: Wiring light switches...

[steve.cooper@xxxxxxx]

I have PIR's link straight into Comfort and Comfort linked directly with
HV
not via a PC.  The respond is usually only about a second.  Any
delay is
normally due to the PIR's being reliant on two pulses rather than
one.  As
soon as the light on the PIR comes on so do the lights.

Mind you there are only two of us moving around the place so a maximum
of
two signals at any one time.  Also, an X10 signal is only sent if the
timer
for that light is not running so an X10 isn't sent everytime movement
is
sensed, this reduces the X10 traffic.

Paul,

I think your problem with response times could be down to the way you
are getting HV to send the on command. I have PIRs connected directly
to
HV, no Comfort in the way or a PC, you walk into the room and the
lights
come on in well under a second, in fact it's almost instantaneous, Phil
has seen this in action too, he can confirm this if he reads it.

In many rooms, such as my AV room or the bathroom, all I need to do is
wave at the PIR and the lights come on. I have said before, I rarely
touch a light switch in the house, or an X10/momentary switch,
virtually
everything is either off a PIR or done by IR in some cases.

Having said that, I have noticed a huge difference between different
PIRs and, additionally if HV is stuffed full of conditions to check
then
the response time drops. Also if you read the command to Comfort, then
to ACE and then to HV then, inevitably, there will be a huge delay in
that and one I would not find acceptable never mind SWMBO! ;)

Not having Comfort (yet) I've never tried routing PIRs through another
machine and, even if/when I install Comfort I would not choose to go
down that route simply due to the problems you describe.

K.
