Phone as key and Tesla WC observations

Oneplus 7 pro. I have decided to turn off walk away looking. Its easier. I always worry about if i have locked the car anyway, So i can just do it via the phone.
I have a OnePlus and have to switch Bluetooth on and off each time. Range is too great and the car was remaining unlocked 6 or 7m away. Easy enough to enable/disable Bluetooth via voice control. Seems to vary a lot with phone type
 
Sorry, arriving late to this thread

TWC/UMC won't open your charge port if the car is locked.

Interesting. Certainly "unlock charger" would be bad if anyone could do it whilst it was charging, and thereby stop your charge prematurely ... maybe that is also a reason to not allow charger port opening when car locked (would be handy to lalow "plug in and charge my car later please ... but maybe there is a future "steal my V2G electricity" threat or somesuch?)

... but I have definitely had my charge port opened, when car definitely locked, when it was parked next to a Supercharger stall - all the cars parked nearby in fact. I assumed that someone else using the "button" on Supercharger wand was the reason. But that was an old pre-facelift MS ... might well have changed

the car will lock if you walk away, or even around the car with your phone. This is constantly annoying for me

Turn off auto-lock?

the phone no longer really sleeps unless you turn off bluetooth.

I read somewhere that was stopping the car sleeping too, and the reason was because the phone location (inside the house) was still in BT range of the car. Is your phone still near the car? if so maybe try a bit further away ... and if that solved it then you probably need to either keep the phone that far away, or turn off BT or somesuch ... in order that the car can sleep ... proper 1st world problem if that turns out to be the case.

Would be nice to look at it without it waking up straight away.

TeslaFi (probably others) will check the Online Status, if it is aware that the car has recently been asleep, without waking the car up. Of course the data it then provides may well be "stale"

The downside of this sort of keyless entry is that it may be subject to a relay attack

I would advise anyone using passive entry to turn ON pin-to-drive. Far too easy for thieves to steal the car otherwise.

What I do find annoying, is that the car seems to prioritise to whoever's phone is in the left seat. So if my wife is a passenger the car will unlock and apply her settings to the driver seat and vice versa.
Anyone else? Or have I screwed up the set up somehow?

I've never put that 2+2 together, thanks for that. I definitely have that. When Wife and I go out I always drive. The seat always moves to her position ... and when I get out at Supercharger to plug in the seat moves to her position ...

It had never occurred to me before but is this an American "Car is LHD assumption" thing do you think?

No the car sleeps fine, just the phone dies a lot faster now. I used to use it as satnav for 2 hours a day + regular browsing and I got home with ~30%. Now if I dont charge it in the car ill get home with the same amount while not using it as much.

TeslaFi (probably others) will check the Online Status

Yeah, that's what I do, but the issue is some times you can open the app accidentally, fat fingers and all that, and that wakes the car... The whole wake up procedure needs to be a lot better (and sleeping). I want to just open the app and select the button for precondition, THEN it should wake the car up and update. Going to TeslaFi on a phone is not fantastic. Right now I open the app in the morning, go to conditioning and the "waking up" message blocks the button, that's just bad UI design.

Also, why can't the damn thing turn off fully? Airport carparks etc...

... but I have definitely had my charge port opened

By the way, there has been at least 2 occasions when my charge door opened by itself. The first occasion it pretty much flapped opened and closed like a little falcon wing imitation until I put the car in drive.

And another pet peeve of mine! 3rd party type 2 cable!!!! Oh god, why isn't there a way to unlock charge port easier? Why do I have to go to the "charge" menu for that when the open charge port button is on the main car display? The amount of times I had to fumble with the phone to get that thing disconnected.... And why doesn't Tesla come with a Teslafied type 2 cable with a button one one end? Maybe I'm just spoilt, but it's really annoying.
 
whats a key fob ? ;)


Actually yesterday, got UMC connector stuck in charge port - was surprised to find that in car display had no apparent option to unlock charge port - it only offered stop charge which was rather dumb as I had the 3 pin plug in my hand and no tesla coil to breach the air gap - UMC blew RCD trip, again. Had hoped I had sorted the problem, but alas not, and I wasn't going to try unplugging the fridge again.

Had to revert to the phone to unlock. Although I did search out the manual release but didn't use it.

A bit fiddly to fit the button, but other than that adapting a Type 2 connector so that it can open the charge port, etc, is pretty easy. I recently modified a connector in readiness for my M3 arriving, and will probably add a similar button to my spare 10m Type 2 lead:

My understanding was that wiring for "Open" is easy, but "Stop charge and release" is more tricky.

Looks like you already discussed that with Arg though:

So... I won’t be getting a Rolec

Yes, the open bit just sends a code using a 433.92MHz OOK transmission to the car. The "stop charge and release" just needs the button to do the same as the microswitch on a Type 1 connector, and switch the PP line.

If using the kit from Tesla retrofit button kit - evChargeking then the wiring bit is pretty easy, and gives full functionality, much like a genuine Tesla cable.

The hardest part is fitting the button. I'm not convinced that the way I fitted the button in the photo above is the best way, as it was a real faff to fit it on the join line of the connector. The button itself is weatherproof, but not that easy to press with a thumb. For the next connector I modify I think I'll try and find a different type of push button, and mount it on the side of the connector, so it is easier to press with a thumb.

I might write up a guide, as the instructions from the manufacturer of the kit aren't great. Taking the connector apart is usually pretty straightforward, as is the wiring, as there's usually two thin wires inside the connector that connect the PP resistor to PE and PP. The resistor just needs to be snipped out and the leads from the kit soldered to them, with heat shrink sleeving to protect the joints. The only other wiring is between the leads from battery module that comes with the kit to the module itself, plus two wires to the push button.

The hardest part is fitting the button, as although there is a fair bit of empty space inside the connector, finding somewhere flat enough to drill a hole and in a place where you can press the button easily, isn't that easy. I'll try and take some photos of the next one I modify, but it won't be for a while, as I want to make sure the one I've just done works OK first.
 
Do you have to disconnect from the mains before you do this?

Ideally, yes, but the cable and car end are isolated from the supply unless plugged into a car that's loaded the CP to the right level, so, if you know what you're doing it's safe enough to do without disconnecting anything (IMHO, but my appetite for risk may be higher than some). You shouldn't get close to any of the potentially live terminals in the connector when doing this, either, as they are well shrouded inside the connector. As a wise precaution, it should be easy enough to make the connector really safe by just flipping the MCB/RCBO in the supply to the charge point, and this would be a sensible thing to do.

Apart from the kit, the other stuff needed would be some solder and some heat shrink sleeving. The tools needed would be the right screwdriver to remove the screws holding the connector together (often T-15 Torx screws), a soldering iron, wire cutters, and something to shrink the sleeving (hot air gun or a lighter at a pinch). You also need a drill to make a hole for the push button, plus a sharp knife or similar to de-burr the hole.

Honestly, at this point I'd love a separate fob just to unlock the charge port. I really wish you could buy a Type 2 "Tesla" cable.

It would be pretty easy to just fit the Tesla button kit into a small fob-sized box. It would open the charge port OK, but wouldn't be able to stop a charge, as to do that needs connections to the connector PP and PE terminals.
