If your tesla has a homelink module, and it shows up on your screen, and if you have tried programming it but the headlights don’t flash, it means your door or gate is not compatible. To fix this you can purchase a reciever from Merlin Australia model E8003 for just under $150. You will also need a corresponding remote E950M to program the tesla. Merlin can be contacted sydney 1800638234. If you are in a different state they will provide a supplier contact. The adelaide guy was driving past my office so delivered it to me 10minutes later. He was happy to wire it in, but its just two data cables so I did it myself. Merlin is owned by Chamberlain who are owned by Gentrix who make Homelink. For anyone in Adelaide the supplier is Advanced Garage Doors 0414400954.
