Hi, I'm designer of Garadget.
@zaphod,
Indeed above dry contact adapter can handle up to 3 openers. It requires separate dry contact sources (relays) for each door. This works nicely if you use a multi-relay module.
Theoretically you can use it with three Garadgets, but because the controllers are mounted on or near the garage door openers you'll have to run long wires to connect those multiple Garadgets to a single adapter. A cleaner option is a separate wired dry contact adapter with each Garadget controller.
@Dr. Venkman,
Thank you for your feedback. I'll look into a garage door proxy situation. Please let me know if you have any other suggestion or questions about the product.
