After only the first delivered Model 3 had the HomeLink on board as standard, I have once resounded to Tesla in the SEC. Retrofit at all no problem, costs incl. installation 320,- Euro and is now installed with me at the service appointment. If installation is desired, this must be logged in beforehand, as parts are not always in stock. One week before appointment has passed with me. Depending on the homelink functions of the gate drive manufacturer, the following functions are probably possible: – automatic opening of the gate when approaching the vehicle (whether automatic closing is not yet clear when driving off) With FSD (with Summon), the gate can probably also be opened and closed via Tesla App. When activating the Summon function, it should also be possible for the vehicle to open the gate automatically. Does HomeLink already use someone with / without FSD?
