Woohoo, something I know something about. If you experience lights turning on randomly, that's usually not a sign of interference as produced by a UPS or somesuch. It would indicate stray signals, for example from a neighbor using X10 on the same housecode. Change your house-code and see if the problem persists. If there's no neighbor in sight, check your -- gasp -- garage door opener. Some older Stanley models will actually generate an X10 signal to turn on an interior light with the garage light. Quite a surprise to me as well, when I first detected this a few years back. That said, a decent noise-filter for any HF equipment (UPS/PCs/Monitors/TV) is a good idea. If you're planning on extending your X10, a whole-house filter and a phase-coupler are also good investments.
