"Goodnight" scene closes open garage door
In my own Ra2 system, I've successfully integrated my garage door "close" function into the system based on the "Goodnight" scene. If the garage door is closed, the door remains closed; if the garage door is open, it's closed (unless there's an object blocking the safety photo sensors, of course). The task is accomplished using a low-cost ELK security relay and a rail-mounted magnetic door sensor, which run around $50 in total. The key to the entire thing coming together is the use of two relays on the VCRX. Relay 1 is wired in the standard way, and is tied to my visor control. Relay 2, however, is used only for the Goodnight scene. The ELK relay wires between the Relay 2 output and the garage motor controller. If the door is closed, the relay is open, interrupting the pulse signal getting to the garage motor controller. On the other hand, if the garage is open, the ELK relay is is "closed", allowing the VCRX's pulse signal to carry through to the garage door motor controller, thus closing the door.
I've had this circuit wired for a month now and it works without fail. Perhaps this information can be of use for one or many forum members.
