RE: 2012 and still no perfect UK HA light switch solution?

["Stuart Billinghurst" <stuart@xxxxxxxxxxxxxxxxx>]

But to see if a light is on/off you need to look at the very same
controlle=
r that you=E2=80=99re going to send the off unless I have missed
something?=
so is status an unnecessary complication, is it just a nice to have but vo=
id of function? Saying that my LX does have status feedback, not built in
d=
esign but because of the way I designed the custom light switches to be
con=
trolled centrally and not via distribution with homevision but it
wouldn=E2=
=80=99t be suitable for retro fit as in the OP=E2=80=99s situation.

I guess I=E2=80=99m looking for someone to point out a functional need for
=
2-way comms in LX design that I have missed.

Not that your remote would be miles away or anything but if I had the
optio=

that the light was already off (thereby staying in bed) I know what I

Isn't the Insteon range supposed to be here very soon? Don't their
products=
have two-way functionality?
