Public API

[GoGoGadgetMachE]

You mean the API used by the app? Are they using some sort of API secret to restrict it to only authorized clients like GM is with their vehicle APIs (see https://github.com/q39JzrRa/GM-Vehicle-API ) , or is it a little more open?

yes, that's exactly what I mean - the API used by the MyFord Mobile app. Someone looking to reverse engineer it would be helped even more by the existence of a fully functional web version of the app, written in JavaScript and HTML. It predates things like OAuth so even authentication isn't super complicated.

Others on here have posted that they used a transparent proxy on an Android device, IIRC, to pull the API for FordPass and it wasn't particularly crazy, either...

The question is does it have anything more useful than what is exposed currently in the app, or any rate limits?

The holy grail here is to be able to give A Better Route Planner access to the car's data so it can route you appropriately as you drive, and so that the ABRP devs can better model the charging curves and usage curves into their algorithms

The API is not protected in any particular way. It's just not documented.
The bigger problem is that there is no oauth2 which means you cannot currently allow third parties access to your data.

I use the Home Assistant integration and gives me more insight than the app (like 12v SoC). I also use it to do my own smart charging (price varies by the hour here) since the oauth2 is lacking.

Home Assistant integration

WOW.

This led to refining my Google search terms a bit...

https://github.com/itchannel/fordpass-ha ?

This is greatly increasing my temptation to trade in my Bolt for a MachE.

Edit: Yup I missed Methorian's post on the previous page.

I'm just a hobbyist, so my yaml coding is all trial and error, but I made this Picture-Elements lovelace card for my Home Assistant. I'm a desk worker (currently remote) so this is easier for me to activate remote start since I always have HA open in a tab. Lock/unlock buttons...eh not so useful due to PAAK/fob. My DTE is wrong, haven't figured that out yet. Works better than Fordpass as well as Fordpass does, ofc ? I'd love to hear about other Ford API smart home/automation use cases.

ETA: I'm using https://github.com/itchannel/fordpass-ha

I was able to find a few values through the OBD2. https://www.macheforum.com/site/threads/ford-mustang-mach-e-extended-pids-for-torque-project.7427/

I thought it was interesting the displayed SOC is to 0.5% but the car displays to 1%. I suspect the estimated energy to empty (kW) and the battery SOC (%) are the actual battery values without the buffers. I need to do more tests and poke around the BECM more. I have been focusing on charging parameters.

In my case - where I sit at work, there is no cellular coverage. Personal devices are not permitted on wifi. So unless a vehicle can be preconditioned by either Chrome running on Windows or Linux, or a Python script, I have to walk out to the front of the building and punch the fob. (With my Bolt, I can usually walk to the car, open the door, get in, and turn it on before my phone reconnects to the towers.)

What you've described makes it sound like I would definitely be able to whip up some Python without much difficulty.

I asked this in another thread but didn't get an answer - when the car is parked in a location where it has access to a wifi AP (such as a home garage), does it use that for telematics communication, or does it exclusively use the onboard cellular for telematics regardless of whether it has wifi or not? (This may seem ridiculous, but Chevy Bolts literally only use wifi to check for infotainment OTAs - which have never actually ever been delivered to any Bolts other than to the first batch of 2017s so GM could remove a feature!)

You should see multiple battery SoC %. One is what is displayed to the user, and another one is the actual pack SoC. Estimated kW to empty is also the usable kW.

If you take the Energy to Empty, and divide that by the SoC displayed, then divide that by 100. It will give you an estimation of total usable kW. (I've been working with ABRP developers to setup live data for the MME)

 

[GoGoGadgetMachE]

it occurred to me yesterday that someone has sort of documented the API already:

GitHub - itchannel/fordpass-ha: Fordpass integration for Home Assistant

I am not a Python programmer but it's a readable enough language that a programmer should be able to figure it out from this.

Hi, where is plug status? I can't find that.

 

[stephywephy88]

Hi, where is plug status? I can't find that.

In (https://github.com/itchannel/fordpass-ha) “Plug Status” shows as a state attribute that equals 0 or 1, so I made a template sensor for 0=Unplugged.

How did you set the charger port as a sensor from the attributes? Do you use templates?

Yes! I forgot about that. If you’re using HA, here’s the yaml I used:

Thank you, I just made the Battery percentage work. I will add more info now I can see how to do it.

Nice job guys, thanks for the tips...
