Thank you OBERKC! Target switch is 2477S, MS-2 is 2842-222, the middle switch is 2477D. I believe the middle switch is able to communicate with target switch because when I had all 3 devices within a scene...(MS-2 controller, middle switch controller, targer swtich responsder), it worked everytime I trigger the motion, but the problem is it is also turning on the light where the middle swtich is located. The phase brdige test shows middle switch and target switch are on opposite circuit. Both circuits are connected with a number of 2477S and/or 2477D. If I'm understanding this correctly, you are saying when MS-2 is linked with the target switch and even though it is out of range, then the signal of MS-2 should be picked up by the middle switch and from there send over to target swtich to turn light on/off, no special setting or links required? Thank you for all the help.

Hoping someone can walk me through to resolve this problem. Thanks in Advance. 2 motion sensors(both outdoor) linked to a switch(indoor). MS-1 works fine, it's about 8 to 10 feet away from the switch. MS-2 works ocassionally, sometimes it would turn light on, sometimes it would do rapid flash and goes out of sync. I assume is a range issue even though it is not more than the 150 feet range stated in the specs......I would say MS-2 is about 35 to 50 feet away and not in a direct line of sight. I tried a scene that set MS-2(controller) to another switch(controller) that's in between MS-2 and the targeted switch(responder), it worked but one problem, it also turned the light on in the room where that middle switch is at. I looked at the scene and somehow the middle switch is both a controller and responsder. So I guess the question is how can I make MS-2 to send a signal to the middle switch without turning on its light, and then the middle switch will send a signal to the target switch to turn the lights on or off? Also, what hapeens if the middle switch light is already turned on and then motion is sensed from MS-2? Can this be done with a scene or do I have to write a program? Looking at the scene, it seems as if I can remove the middle switch as a responder, then it should work, but then I can't remove it as a responder or I don't know how. Thank You!

Thank you all! I guess I have much more studying to do.

Thank you Ober. Under admin console, I click the scene name and then click ON, both dimmers' status shows ON and the light fixture is on. However, how do I make the dimB work too under the ISY device list? Or why won't it work just like dimA when I click on it? I believe dimA is the actual switch turning the light on, and dimB is just sending a signal to dimA to turn light on, am I doing something wrong there?

Thanks in advance for any advice or help. Installed two 2477D dimmers as 3 way on a light fixture. Linked both dimmers into ISY994.....named dimA and dimB Created a scene and added both the dimmers and set both as controller. Both dimmers works fine when I go to either location to physcially turn on, off, or dim by hitting the switch. However, within ISY994, when I'm at the home interface or admin console, I can only control the light fixture clicking on dimA. When I click on dimB, the light doesn't turn on, off, nor dim. Going over to dimB, I will see the led light on the dimmer all the way up but the light fixture isn't on, I then hit the off button on the dimmer, led light goes all the way down, hit the on button, led light goes up and then light fixture turns on. Within ISY994, how can I control the light fixture using either dimA or dimB? Or that's not possible at all. Thanks again.
