Dan and I have discussed the dimming issue as it applies to Insteon lights. These lights are a little tricky in that they apply ramp rates to a group command, rather than an individual command. That is to say, there is no way to tell a single device (of the current generation) to say, dim to 50% over x seconds. However, when a command group is created, a device can know, when it receives a command targeted to a group of which it is a member, it should dim to x% over x seconds. Right now, LMCE isn't set up to handle Insteon group commands, only individual commands. It's going to take some work to modify the lighting module to support this.
