Ok, here's what I have now know about the issues I've had with MyHouse showing lamp modules incorrectly. If the lamp module is defined in AHP as an older non-soft start one, MyHouse Online only shows the module address and status, ie green light on/off. If the lamp module is defined in AHP as the newer soft start, then everything shows, the address, status light, on/off toggle switch and the brightness slider. They appear to work properly but I can't tell for sure since I don't own any of the newer modules.
Once again X10 has failed to fully test their various software programs before rolling out what should have been a minor upgrade to include the newer modules. What ever happened to regression testing!!!!
