I've got Homelink setup on my garage door and it works fine from my car's touchscreen to manually open/close. I've got summon setup and it works fine from my app. I've updated to both the latest App and the car's software. I've heard that I should be able to control Homelink from my app, but I haven't been able to figure it out, and the local Tesla dealer couldn't either. I was told by another Tesla owner that an icon for homelink will appear on the Summon page so I can manually open & close the garage door, but I don't see anything. I've tried turning Homelink on & off from the car's Customize Summon page to no effect. How is this supposed to work? One thing that bothers me is that I have a really old garage door opener - 1989 (hey, they built them to last back then!). I was able to program Homelink to my old door no problem, but I've read that Homelink can now talk two-way to communicate if the door is up/down for example. I've read the Tesla manual and it doesn't mention if Summon & Homelink require such two-way communication to operate but I have a suspicion this is the problem. I've tried turning on Homelink to auto-open & close but that's never worked... that seems like more evidence this is the problem. Does anyone know if there's a requirement to have a "new" garage door opener, or what's the oldest garage door opener that is working for someone with Summon or auto-open/close? I'm not planning on using auto-open/close but I would really really like to be able to open/close the garage door manually from the summon page of the app.
