Community help needed - Underground garage & wifi summon...

    Greetings All

    I have originally raised this point with Tesla (mail to ServiceHelpEU <[email protected]>) - briefly the problem is:

    I have underground parking here in Switzerland. It is very, very common. Along with running 400v triple phase to my two parking spots, I pulled a few strands of Cat-7 ethernet cable as well. On one of those is a wifi access point, which works well. My P90D can connect to the access point without any problems.

    As far as a cellular data connection goes there is nothing (neither GSM nor LTE). As there are many tons of rebar and concrete overhead, this is to be expected.

    I would really like to be able to squeeze my Model S against the wall by using summon to back in. This is currently not possible because of the behaviour of the car. If I summon the car (connected to Wifi) it stops just after going from P to D or R. The Wifi connection drops and try to switch to cellular as soon as the car goes out of park. Tesla says this is normal.

    Several software releases ago Wifi summon worked (in one direction). My delivery guys says more emails to ServiceHelp will help the problem gain visibility.

    Thinking about potential fixes:

    1. Do not disconnect the wifi connection if there is no one in the front seat (I am assuming here that there is a system accessible pressure sensor in the seat)

    2. Re-enable summon via the fob for those of us in underground parking (which is the norm here in Switzerland). Another DS has said for liability reasons this will never be enabled here...

    3. Use direct app-to-car via Bluetooth for the summon functionality.

    Any one of these three would fix the issue; The first option is likely the best and most straight forward to implement.

    I have explored putting in an LTE repeater in the garage. The minimum I can get away with is 3,000 CHF, which is a bit more that I want to spend.

    So, for anyone in the same boat, please send an email to the address above (feel free to copy my "problem text").

    Many thanks

    P

    I have a similar issue. my garage is not underground, but the mobile signal is week, so the summon feature works about 25% of the time, and often doesn't work or stops half way with connection issues.

    I was thinking of buying a booster signal box from phone operator which gives 3G signal when connected through internet... these things only cost about $100 from the mobile operator, but I need to find out what mobile network Tesla is on in the UK (I think it is O2 / Telephonica).

    Or I was keeping my fingers crossed that Summon by Keyfob will come to UK on the next software update... but sounds like there might be legal reason why they have not done it yet, so wont hold my breath.

    Mobile Booster box seems like the cheapest option - to try first. Anyone tried this yet ?

    What firmware version are you on? I thought Tesla had already fixed this. (But you do need to let it disconnect once, and then while in Drive reconnect to the WiFi. That is supposed to mark that WiFi network as one that will be used during a drive and not disconnect in the future.)

    Or maybe their fix was to let it disconnect and then reconnect a moment later which would break Summon.

    Currently on 17.14.23, although I have not yet tried summon on this release. I'll give it a go tonight, but I doubt it has been fixed...

    What's wrong with using the keyfob? Does Europe not have that functionality?

    Also, if you double tap the parking lever, it brings up the summon/autopark screen. So you can park it that way, but you might not be able to bring it back forward...

    I think both of those options are only available in the US. Almost everywhere else essentially requires a dead-man switch.

    No, key fob in Europe is not allowed. And I just checked 17.14.23 in the garage, no go.

    And you have reconnected to the WiFi after you put the car into drive?

    No, I am standing outside of my car, attempting to summon it from my parking space (where the drivers side is squeezed up against the wall). If I have to try to open one of the car doors, then that defeats the entire exercise...

    I'm saying that you have to do it at least once before that WiFi profile will get flagged to stay connected when you shift into drive. And once you have done that maybe Summon will work for you. Consider it a "setup" step.

    I have a similar situation, except I dont have WiFi.

    Instead, on LTE, the app tells me to stand closer to the car, even if I am standing right next to it.

    I think this is a GPS issue.

    GREAT !!! Problem seems to be solved - Thanks MP3Mike !!! How did you find out about that little trick ?

    I tested Summon on my X90D AP2 and my phone signal was on Zero - and Summon Worked !! So this should work for Peter too if you follow Mikes instructions :)

    It was something that @Ingineer let us know back when 7.0 broke things and started disconnecting WiFi when you shift into drive. I guess it worked like this for a while, and then it stopped setting the flag to let it stay connected, and then Tesla finally fixed it again.

    Tesla said the reason they did this was to make a clean transition from WiFi to LTE when you leave your house. (As people were complaining about streaming music and map loading not working as you drive away from your house as the WiFi signal gets to weak before it switches to LTE.)

    No luck on my side. Reconnected to Wifi after shifting to drive, put in back into park, then tried summon. Same thing for reverse...

    Hi,

    I have similar problems in a parking structure - good LTE but no GPS. I can confirm the car needs
    1. Data connection WiFi or LTE
    2. Phone connected to WiFi or LTE
    3. Key fob within range
    4. GPS location for both phone / car to be close to each other.

    Loose any one and Summon stops. I think they have a deadman logic that goes
    1. Fob needs to be near car
    2. Phone needs to be near car
    (otherwise you could summon your car from the other side of the world if someone else was stood near it with a key fob.)

    Have asked Tesla for a better way to make it work - e.g. Bluetooth to prove phone is near car and key fob is too.
