In the previous post, I described two of the three significant X10 problems we had when setting up our home automation system. This post will cover the third problem, latency. Although all our lights have conventional switches (well, momentary switches in conventional locations), we use a lot of X10 RF Remotes and X10 Motion Sensors to trigger lights and other devices. Initially, we used a TM13U RF Transceiver Module that receives the X10 RF signals and converts them in to X10 powerline signals.
