I plan on using MCE as a home automation controller before I get it setup as a media controller b/c I have a bunch of X10 stuff already and an Insteon PLM.
I was able to get the PLM to send commands to the X10 lights I added under Wizard-> Lights
The lights I create stay in the Wizard for a while for a while and I can add them to a floor plan, but then a little while later, they disappear.... It's defiantly a time based issues as I can restart/reload/regen and the lights will still be there after, unless I meet some unknown time limit. Seems to be around 3-5min
