Power line comms X-10

Status Request doesn't work with dimmers either. The newer modules that support X-10's extended comand set do accurately report load status, including level, but the TW523 class controllers cannot receive the codes.

Most of Smarthome's own brand of X-10 switches and modules respond to Status Request and even report changes (bulb burns out, switched off, etc.) in status, using the standard Preset Dim commands, so they are the way to go if you want accurate status reports using TW523 class controllers.
