I'm just a little giddy at the moment. Even though it took considerably longer than I thought it would (like 4 hours), I got the Harmony 900 set up; programmed and working the way we want it to. Yes.
I still have to tweak the GE QS page to select scenes and to mount the main blaster in front of my rack instead of sitting on a box, but the remote and RF is working as expected.
Speaking of the QS, I thought that it wasn't working with the 900 (primarily because the web set up said the 900 couldn't control it). As I was flipping through my QS manual, my son walked in. He picks up the remote, presses a couple of buttons and turns up the lights! Then he says, "Didn't you tell me not to read in the dark?" or something. "How did you do that?", I asked. He knew he had me so he clears his throat and says, "Dad, it so simple, 'Devices, Lights, +Brightness'.
He'd never seen the remote before and walks in and teaches me something new in 3 seconds. I felt so old...and grateful.
It also felt good when my wife took the 900 for a brief testdrive by pressing the 'Watch TV' button.
No more running to the equipment room to pause the movie or change the channel.
Thanks for the help.
