Getting Data from Car?

[Benjanos]

Hey Team,

Looking for ideas and feedback on Tools/Apps that can connect to a Model S and provide additional data on the car. I’ve seen on Youtube there is a cool program for Nissan Leaf (Leafspy?), is there anything similar for Model S? Telsafi seems like a logging app but seems it more about charging.

I am more interested in getting real time data on

• Temperatures of the various components
• Charging information such as real time kW/Amps/Volts/SoC
• Consumption of various subsystems, charging/heating/battery heating

Any clues? A bluetooth OBD connector straight to the iPhone would be cool, but hmmmmm not sure that exists?

Here is one - Vendor - Scan My Tesla, a CANBUS reader for Android

Not something I have tried, just read about. May be others too. I believe some disassembly required.

Turbo3, the maker of LeafSpy, has a similar app for Tesla's called TM-Spy. It requires an OBD-II dongle to scan the car (which requires a special cable for a Tesla).
Helpful links to TM-Spy threads.

I used LeafSpy on my LEAF, but I don't use TM-Spy. I haven't seen the need for cell-level tracking on the Tesla (yet), since Tesla provides so much information in the car (something Nissan does not).

I use TeslaFi to collect and record the data from my cars and give me nice reports. It is not just about charging! It just uses the Tesla API to collect information, and it's website reports are pretty indepth. TeslaFi has a small cost, but they provide a free trial. If you use my TMC username as a referral code when you sign up for the trial, it will last 4 weeks.

Here are some posts I've made showing data collected from TeslaFi:
Danbury, CT Supercharger (charging summary)
Sunday River Ski in Maine- 3 Tesla Chargers (trip map)
Danbury, CT Supercharger (lifetime map)

Yep! This forum is really the best

Thanks already for the responses, loads of stuff to followup on. Once I settle on something I will try and come back here and summarize what I found useful.

Cheers

Keep in mind that different tools have different ODB2 requirements. You will likely need different dongles if you switch tools.

Researching is continuing. Below are two nice youtube reviews made on the main two Apps. Its the same guy making the videos which is good. I like the look of Scan My Tesla so I will proceed in that direction.

TM-Spy

Scan My Tesla

Just now trying to determine three things

1) What cable I need to make Scan My Tesla App work. I have my eye on this cable, but will email the site to make sure it takes all the data Scan My Tesla can display. Tesla CAN Diagnostic Cable (Sept 2015 and up) – Crimped OBD-II – Maxwell Automotive Technologies The reason I am unsure is the site makes you specify which CAN Bus you want the cable for (Body/Powertrain/Chassis)

2) If there is any chance to get Scan My Tesla working in iOS, else I'll have to buy an Android device. Which is OK but would be easier if I could just use my iPhone
- sub question, I wonder if a small Android tablet would be OK/Better than just an Android phone

3) Which OBD-BT adapter to get

 

[Benjanos]

OK questions 1 and 3 answered. RTFF!

1) Scan my Tesla listens to CAN3 (Powertrain) so you need to order the cable as such on the link above if you get your cable there. Thats easy.
3) Scan My Tesla have this link explaining the adapters they recommend. Cool... scan my tesla - Reccommended adapters

Stay frosty team, I am still chasing some stuff on this one but fully intended to report my "goofy guide" on how I did this starting from zero experience and knowledge.

It would just be awesome if Telsa had an engineering mode on the MCU, the CAN data is all there anyway so why not give us the option to view all the technical data blasting around on the CAN buses?

 

[Benjanos]

OK so I finally got the parts together to make my CAN bus scanning work. I used...

This cable: You need to be careful which one you buy depending on the age of your Model S
Tesla CAN Diagnostic Cable For MS/MX (Sept 2015 and up) - Crimped to Order OBD-II

This ODB Scanner: It seems there are many but this one is somehow recommended

This Software: Scan My Tesla which I have only just begun to explore but its quite amazing. Downside is its Android only, so I borrowed an old phone off a friend
scan my tesla


Just a few sample screenshots below, the amount of data is impressive

Hi, thanks for the support, and I don't know if you know that we have an official thread here:
Vendor - Scan My Tesla, a CANBUS reader for Android

Any questions, suggestions, bug reports, I am all ears.

Thanks Amund7! Will let you know. Need more time to play
