How to wire Insteon switches for 3-way circuit?

I was told there's no such thing as Insteon slave for 3-way circuit. So how am I supposed to wire them up in a 3-way circuit? I've been replacing switches in the house including x10 3-way, but my background in wiring is not so good :unsure:
 
Basically, there is no 3way Insteon WIRING. Wire one switch to the hot and the load wires as a normal switch. You may need to use one of the 3way traveler wires to bring hot into the switch box. The second switch is just linked (tap-tap or link management software) to the first switch. If you wanted to add a third switch, you would just link it also.
 
Ok, this sounds too easy :unsure: Basically once I figure it out where power comes into which switch, I just wire the HOT and TRAVELLER wire together, then the traveller from the other end becomes HOT, then I just wire the other switch at other location.

That sounds too easy! Thank you. V2 Insteon is not as deep as traditional Smarthome x10 switches, right? I have found a few gang boxes aren't as deep and lots of wires behind, so I'm hoping these new switches will help.
 
What you have to watch out for is this. In a 3-way conventional switch wiring, power is brought only to one of the three way switches, and then switched to the second switch. SO when installing Insteon in a 3 way config, you may have to send power to the second switch (the one with the load) accross one of the "traveler" wire. See diagram.

btw and somewhat off-topic, redneck electricians don't understand this no matter how many times you explain it. I had to redo all my slave switch wiring because they just didn't get it. :unsure:
 
Thank you very much guys, now I know what to do! I had an electrican yesterday to install a few outlets, and I was asking him and he told me impossible :unsure:

Were they "redneck" electricians? :unsure:
 
Tried my first 3-way switches, I only connected one Insteon switch and the load won't turn off even the Insteon switch is in OFF position? Do I need the 2nd switch installed before this will work?
 
Made a mistake, the load was actually from another 3-way switch outside the room. In any case, the load actually doesn't come on at all. The switch is energized but on/off doesn't do anything.
 
I should ask too, I don't actually have any Insteon transmitters, so will I be able to link a 3-way in X10 mode?

Thanks again.
 
Got it, I had to bring power to the 2nd switch. Now I just need to figure out a way to link them together. I guess I can use the same X10 address for both switches? Or is there an internal way of linking them regardless of the X10 address they use?

Thanks.
