Momentary contact switch using Insteon? RickH 08-03-07

Can anyone explain how to create a momentary switch behavior using
Insteon? Where if the user is physically holding down a button then
the lamp is lit, conversely, when the user lets go, the lamp goes
out. The lamp should never light unless the button is held down,
conversely, the lamp should never go out while the button is being
held down. IOW the lamp is normally off and only on while someone is
holding the button down. Is this possible using any of the standard
Insteon products?

I don't believe it's possible or desirable. It would require continuous
powerline transmissions, blocking all other activity.

It would be possible if the switch itself sent a single on command when
depressed and an off command to the same address when released. This would
leave the powerline free while the switch was depressed but I'm unaware of
any Insteon switches that can do this.

You might get better answers to your Insteon questions on Smarthome's
Insteon Forum.

What is it you want to do? If it's something that others might think useful,
Smarthome might respond by designing/programming a switch to accomplish it.
You might even be able to do it yourself if you buy their SDK although I
haven't really looked into whether this would indeed be possible without
changes to the hardware (i.e. I don't know whether it can sense switch press
and release).

I just entered a pending question to SH. I want to control a drape
motor and have the motor stop at the exact place I lift my finger off
the button each time. It is up to the user to lift their finger where/
when they want it to stop, (this is an existing motor with an existing
wall pushbutton). Re-applying power a second time and motors travel
in reverse, etc. so you can make a stop while it is going in either
direction. The motors automatically stop when the outer/inner limits
are reached. Considering I need great accuracy, (IOW no motor overrun
when I lift my finger), I will probably bite the bullet and just hard-
wire a second switch at my seating location. But it would be nice to
do it wirelessly.

thanks

I got an answer, however it seems like it will introduce time lag and
using non-wired control always leaves open the possibility of a motor
running when I dont want it to. So I'm going to use a small ELK relay
board at the outlet and hard-wire a low voltage pushbutton at my seat,
setting up the relay board for momentary mode (I hope). This way I at
least wont have to run line voltage anywhere.
