Does anyone have the IR codes that allow programming of a Roomba robotic vacuum cleaner with scheduling information? I have a Discovery model that has a remote, but am told by the folks at iRobot that the scheduling capability is built into the main unit. They want to sell me another remote that apparently builds a custom IR string that is then sent to the main unit to program its start time. I only see doing this once (or as a refresh after a battery change) so rather than buying the special remote, I'd like to program my universal to send the programming.
