Garage Auto Opens, won't Auto Close

edited November -1 in Model 3
My sister just picked up her Model 3 (with 2018.24.8) last week. I've had mine for a couple of months (2018.21.9).

My garage door opens when I approach and closes when I leave, just as it's supposed to. Hers does not.

It opens fine when she approaches. The HomeLink indicator shows "Opening in 10 feet" etc, and then the door opens. But when she leaves, it never even shows the HomeLink indicator that closing is pending. She can reach up and touch the icon, then touch Home, and it closes just fine, but for some reason the car doesn't seem to know that she is leaving home.

Any ideas, suggestions? We reprogrammed the opener, and reset position and distance a couple of times, to no avail.

    Strange. Have her program your garage door opener into her car and vice versa. If the opposite occurs then you know it’s her garage door system. While I can’t help in how to solve the problem, at least it will tell you there’s nothing wrong with the M3 and her garage door system works differently than yours.

    Try to reprogram again. I think mine also did the same the first time I programmed it.

    Join the club. Exactly same as mine. It does not try to close even. It’s not an issue with my programming the HomeLink. So must be a firmware issue. Taking into SC in another week for this and other issues. Have a number of other firmware issues as well.

    Check the light bulb in the garage door opener. If it is an LED, it may interfere with the Tesla’s signal. Try replacing it with an old fashioned incandescent bulb.

    Opening the garage door works because the light is off when the signal is sent. Closing doesn’t work because the light is on when the “close” signal is sent.

    CFLs can have the same interference issues BTW.

    @Madatgascar I like your working assumption. They say they can close the door manually with the TESLA. Do you think the automatic signal would be different than the automatic? Maybe weaker or ???

    Meant to say automatic different than manual?

    There are separate Homelink settings for auto open and auto close. Make sure both are selected.

    @magic - OP may have a different problem, but changing the light bulb worked for me. They may have tried the manual control after the light timed out.

    Manual open and close using HomeLink works with no problem. Only auto close is an issue. It is clearly a software issue since auto close does not pop up on the screen like the auto open pops up allowing for a skip of open or close. Firmware bug in 24.7.

    @Madatgascar That is good information. Light bulb interfering with signal would be something most, including myself, would probably not think about. How the heck did you figure that out?
  • edited July 2018
    Simple - take out the light and see if you still have the issue :)
  • edited July 2018
    Definitely simple to test I am wondering how Mada' thought the light could be an issue in the first place.

    @Chris35
    That's an ingenious suggestion, programming each car to the other's garage to see if the problem is the car or garage door opener. We will try that.

    Regarding the discussion that it might be the bulb, as Atoms points out, it works when manually pressing the icon, but the HomeLink "Auto-close in 10 feet" message never shows up, so it's clearly either the GPS, or something else in the car.

    Oh sorry - I misread your statement. LED bulbs are a known cause of electromagnetic interference. It depends on a wide variety of factors (e.g., some do and some do not) which is why it may or may not be causing the issue.

    Could be GPS issue. Try resetting the GPS location. Does she back out of the garage?

    @Daryl I have same FW as you. I have a somewhat similar problem, but it doesn't always happen. The auto-open works every time, but the auto-close is sporadic. When I'm in my garage and leaving I immediately know whether it will work or not when I put the car in drive as the auto-close dialog will appear (or not). Haven't spent any time trying to figure it out.

    Sounding like a memory leak or overlapping memory locations for variables. The status of “skipped open” carries over to “skipped closed” even though I never request close and no prompt to skip close pops up. Given that it is sporadic for some and never works for me is making it sound not like a coding logic error but an error in memory management by the programmer. One of the major weaknesses of programming in C. Maybe need code reviews before release.

    I have exactly the same experience. Auto-close worked the first 2-3 times, then notified us that it auto-skipped closing thereafter.
  • Mine works great for about 2 days and then nothing works, I've reprogrammed 3 different times with the same result, works great for 2 days and then poof..... nothing, won't open, won't close. Anyone else experience this?
  • edited July 2018
    I find that auto-close doesn't always work when leaving. It's not a reception issue; the auto-close notification doesn't pop up on the screen at all. I get the feeling there is some rule about when it will be used, like the timing of when you turn on the car, open the garage and start backing out, but I haven't figured it out yet. Hopefully this gets improved in an update.

    Same issue with me. I setup my garage door a couple days back and the auto-close does not work. The auto-open works correctly.
  • edited July 2018
    Add me to the list: auto-open works every time, auto-close has yet to work. Have 24.8 as delivered 5 days ago. Garage door had a 100-watt equivalent LED which I changed to incandescent...no better. Hoping that 26.1 might fix if and when I get it. If not, I’ll create a list of things for the SC. To date, I have nothing else for that list.

    I'm the OP. I have done a little research that may shed some light on this issue.

    I didn't realize it, but the more recent versions of HomeLink are 2-way. The garage door opener can inform the car of its condition (up or down). This requires that the car be able to communicate with the opener.

    With a CFL or possible LED bulb in the opener, it can interfere with radio waves. The opener might be able to receive the raw signal to close, but it might not be able to establish a handshake with the car to inform it of its condition..

    If the car is waiting for that handshake before preparing to auto-close, it might explain the problem. When you are leaving hoime, the light is always going to be on. When you come home, usually not.

    After my sister took out the bulbs in her opener, it started working well. We'll follow up on this to see if it really made a difference, or if it was a coincidence.

    To those suggesting bulbs as the source of the problem, I apologize!

    Mine has the same problem. Auto-close has never closed it. When leaving, it never "dongs" to indicate it even tried.

    I don't know if LEDs in the opener are the reason or not, but manually hitting close works every time. The idea of a 2-way Homelink handshake that is getting disrupted is interesting, but I dunno. My opener is at least 10 years old, when did 2-way Homelink roll out?
