They're all GET calls. Hadn't tried in the browser, but according to the experts, it won't work in the browser.

I returned from some out-of-town work yesterday afternoon. I thought that I would test the notification situation before going home at the Fresno Supercharger. I started checking the status from Merced (about 45 minutes out) every ten minutes. The status consistently showed "7 of 10 stalls available."
When I arrived, surely enough, there were three Teslas plugged in. I plugged in and set my charge to 80%, (40 minutes per the timer). It took about 3 minutes before the screen reflected my arrival when it changed to "6 of 10 stalls available."
I got extremely lucky during my stay. One car left, and three more showed up within 15 minutes. The change to the display would take 30 seconds to about 4 minutes to reflect the addition or removal of vehicles.
I noticed that even when there were 7 of us charging, there was never any mention of the forty-cent idle fee. When I completed my charge, two more people had departed, and we were down to 5. I never received any notification that my charge session was completed or nearing completion.
For the next five minutes after charging, I kept the cable attached to the car. The display still said "5 of 10 stalls available." I then removed the cable and hung it up. Upon returning to the driver's seat, the display dropped to "6 of 10 stalls available" within a few seconds, even though my car was still parked in the stall.
So, I gather that there is a periodic polling between cars and the Master Supercharger Confluence and Information Center to determine availability. I also gather that occupied but not connected or ICE'd stalls are not known. This might possibly explain why some locations have wordage like "3 stalls possibly available." Perhaps these locations might have the "General Parking - 60 minutes" signs that permit anyone to park in a SC stall for shorter periods. Fresno's 10 stalls are dedicated to Tesla; no general purpose parking is permitted.

Almost any [necessary] supercharge will take upwards of an hour or more without a destination in the nav.

I've made a number of updates to the Realtime Supercharger Map Today - Tesla Supercharger Realtime Availability Map - EV-Prices - Tesla Price History & Modeler
If you run into any problems or have suggestions, please send me feedback.
- UI Cleanup
- Responsive AutoSize for large screens
- Saves position and zoom in URI fragment to maintain state after Refresh or in BookMark
- Performance Improvements (using MarkerManager to avoid drawing offscreen SC's)
- In Car Mode when running from Tesla Browser
- Auto Zooms to current location every 30 seconds
- Only pulls data for SC's in view to improve performance (car JS performance is terrible)
- Availability History coming soon (wk057 is working on it)
If you run into any problems or have suggestions, please send me feedback.

Any way to add the service center superchargers to your excellent work so far?
(For example, the Tesla Service Center on Grand Avenue in Chicago has 2 SuCs that are not shown on the Tesla website or on the in-car browser).

Basically every other public charge network displays realtime data to the user and have done so for several years. I don't see how collecting this data is any different.

Service center SpCs may not be for public use. Costa Mesa has one only to test fast charging or to quickly charge up a car before returning to customer.

Agreed, but I have used the Grand Avenue SuC and SC personnel say it is ok. Maybe a site by site decision, which would make it impossible to automatically include or exclude.
My question is whether the data is even there.

It might not go through the same VPN the internal telemetry traffic does, but it certainly does go through Tesla's VPN when on 3G/LTE.

Well, I just know if you ping the IP address in the browser, it's never AT&T, but a cloud VPN provider. It used to be Jasper Networks, and now it's Oak Ridge Networks or something like that (I can't remember).

Unless Tesla is publicly saying these sites are open I am hesitant to show them.

Just because you sniffed it doesn't mean it doesn't go through a proxy.
Yes, but a proxy is not a VPN. I'm not positive, but Tesla's VPN likely uses high grade 2048 bit RSA or higher encryption. There is no way you could sniff that traffic without it being useless garble. The point is that the browser does not go through Tesla's VPN.
