Tesla's implementation of Home Link has always been faulty. It was bad in the early Model S cars, and they did nothing to correct it in Model 3. I've never been able to set my activation distance to more than 30 feet. If I try, the door activates, rises about 6 inches, and stops. This necessitates coming to a dead stop, manually lowering the door and then manually raising it. When set at 30 feet, it works properly every time, but at that distance there isn't time to raise the door sufficiently, so I have to come to a dead stop to wait for it to rise. I've tried repeating the pairing process a couple of times, and I extended the opener's monopole antenna all the way to the front of the garage with bell wire, all to no effect. Maybe in the Model ?, scheduled for release in 203?, Tesla will re-engineer this problem, but it's been obvious through many threads on this forum through the years, that, so far, there's never been anyone at Tesla who gives a rat's a__ about this nasty shortcoming.
