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

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.

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, 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.

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.)
 
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.

Hi guys,
I also had the same problem, have an underground parking lot.
The main problem is GPS signal which wont be available underground and tesla mobile app needs them to send to tesla servers.

so If you have internet connection in the garage then you could create a small program to send summon commands "faking" the GPS coordinates. Basically you can read the coordinates of your car and send them in the summon request.

Check this link for code examples by Tim.
Add support for new Summon APIs · Issue #16 · timdorr/model-s-api · GitHub


I created a small script in javascript using node.js that i can call via computer/phone which will issue a summon (autopark) command in an underground garage. Tested it yesterday and works great :)

I have the teslams framework installed so I can take advantage of that to query the car for nrrded information (GPS coordinates and token) .

Hello,

Some members have asked me to share the autopark script with them. The code has been taken from different sources like timodorr
- Add support for new Summon APIs · Issue #16 · timdorr/model-s-api · GitHub
and also the teslams framework from hjespers
- hjespers/teslams

I just put together the pieces and created hyperlinks to access the autopark functions.

be careful while using it, I DO NOT bear any responsibility by the usage of the script, I'm not responsible if you crash your car while on autopark.

The car will ONLY stop if you press the KEY FOB or there is an obstacle (tho I never fully trust the latter).

Basically this script will run on a computer with node.js installed, it will open a http server listening on port 8888.
you can access this webserver from your phone for example.

if your computer's IP is 192.168.1.2 then you can connect from your phone opening the web browser like this:
http://192.168.1.2:8888

if you connect from outside your home network you will need to access your computer with public IP and probably forward the port 8888 from your router to your computer

you will have 3 links to click. First you need to click "getInfo", so that the script will read the GPS coordinates from the car, then you can choose "forward" or "reverse".

Be always prepared to STOP the car with the key fob.


Code:
#!/usr/bin/env node

var teslams = require('../teslams.js');
var request = require('request');
// edit the ~/.teslams/config.json file to contain your teslamotors.com login email and password

Same issue, except that my iPhone won't even connect to my Model 3 in the underground car park. I can open the doors (presumably through bluetooth) but no way of summoning as the app won't connect. There is a very weak LTE signal which bizarrely means I can connect to the car when I'm in my flat, a few floors above! Any ideas how I can get the app to connect to the car in the garage? Get a wifi signal, is that enough ?

Hi All,

i created an Android APP that can run directly from your phone, this will greatly simplify the setup without the need to install node.js acting as a webserver.

The app is in a ZIP file, because it wouldnt allow me to upload the *.apk file.

be careful while using it, I DO NOT bear any responsibility by the usage of the APP, I'm not responsible if you crash your car while on autopark.

The car will ONLY stop if you press the KEY FOB or there is an obstacle

This is a very basic APP, dont expect fancy stuff, I just did the minimum to be able to summon the car. It works very good, never had an issue.
there are 2 pages:
- Login page
- summon page

on the summon page
The back button acts also as a stop, to cancel the summon, but always be prepared to press the key FOB.

when you press "forward/reverse" the app will start the connection to tesla for summon. this might take a bit, so dont keep pressing the button. there will be some output on the screen informing in which state the autopark is.
Ideally you should be starting when it states "Ready for summon".

the button check car status is there to refresh the status, if the car is asleep and it became online, you need to press that button so it will read the GPS coordinates from the car.


btw: the Password is not saved, so you need to re-enter it each time. Maybe in the future I will save the token (not password) locally, so that can be used until it's valid.

Enjoy
