We're just getting started with an Insteon home automation system. There are a few light switches in our house that I'd like to be able to control remotely (for example, our outdoor lights are accessible only from the garage), and there are others that I'd like to be able to control in tandem - for instance, setting "scenes" in our living room, dimming certain lights and turning others off when we watch a movie. Just recently, however, Belkin announced some additions to their WeMo system - including light switches - that may make the system a plausible alternative to Insteon. Let's compare and contrast.
