3-way Wall Switch

I have a light in my basement stairway that is on a 3-way switch. I want to be able to turn on that light from the switch and have Indigo then turn on my TV room light then if I turn off the stairway light have Indigo turn off my TV room light. Is there an X10 switch available to accomplish this?

Thanks for your help!

RonJon,
I would use one of these (with the companion switch, for a three-way) to do the job.

If you want dimming use the 2380. If your TV room light is on an X-10 switch, then you only need to program the hallway light switch and setup a trigger action in Indigo that turns on the TV room light whenever the hallway light transmits its address.
There's about a billion other ways to do this but I really like these switches and the logic of this arrangement makes sense to me.
Hope this helps.
