RE: X10 Questions

["Mark Harrison" <Mark.Harrison@xxxxxxx>]

1: Depends on your house wiring. I can turn on an appliance module in my
garage from a controller in my bedroom. My garage electricity is on the
same mains ring as the house though.

2: The advantage of using a wall switch is that it's a plug and play
replacement for your existing switch (see 3.) The disadvantage with the
LW11s is that you can't dim all the way to pitch black (dim to 0% is not
the same as off - there's a glow.) If you turn OFF, then turning back ON
again, comes on at 100%, and then dims to the desired level :-(

On my light modules (which I have bedside lamps on), I can dim those fully
to black. This means that, in the morning, I can dim on 10% at 6:30 then
progressively up over the next 15 minutes.

3: Yes. The bad news is that pressing the switch DOESN'T send any status
onto the X-10 network. Nor do the switches respond to status requests. That
means that no central controller can reliably keep track of the state of
the LW10s.

All my comments are in connection with the LW10 modules - I don't know if
there are newer versions that deal with these issues.

Specifically, I gather that the LD (din-rail module) does support SOFT ON,
so that it can come back on to 10% from dark. The downside is that that
requires quite a bit of extra installation over and above just swapping a
wall switch.

Regards,

Mark

Subject: [ukha_d] X10 Questions


Hello,
Just a few X10 questions from a beginner:

1. What's the maximum distance that the X10 transmitter will be able to
send
a signal? (for example will I be able to switch on/off a light/appliance
in
my garage which is not adjoined to my house?)

2. What are the advantages/disadvantages of using an X10 wall switch over
an
X10 light socket?

3. Will I still be able to use the light switch to switch the light on
and
off regardless of what state I last left the X10 light switch
controller?
(for example if I have switched the light off via X10 will I be able to
walk
into the room and switch the light back on with the light switch?)

4.I saw mention of an IR controlled/touch sensitive light switch from
TLC
Direct, can these be used in conjunction with an X10 socket?

Thanks in advance.
