Chris - sorry - I meant do I need two transceivers and that the transceiver is set to house code B. See I told you I was uneducated. To give a little more insight, I was trying to get a Slimfire Remote to work on house code C and Homeseer never would receive the signal. I was watching the little red light on the amplifier coupler and it never came on when I pressed a button on the Slimfire. I had another transceiver around and I plugged it in set to house code C and the Slimfire started working. It's been a little frustrating because things are an inch away from working the way I want.
