By now we all know that Renault are slowly releasing a successor to the ZE Services app they crippled at the end of last year.

@yoh-there's post sounded like a challenge to me, so I spent a little while poking around to see what I could find, and I've written up the results here.

It gets technical very quickly, so is probably not a mass-audience post!

tl;dr: it's a lot harder to authenticate to the point of getting data out; the information available is mostly the same, at least with respect to ZE-specific stuff, with a couple of so-so additions; for app developers, there's not really a compelling reason to try switch to the new API, until they turn the old one off - if indeed they ever do so.

Sjeez (skimmed over). Thank you!! Need to think hard if I want to code that in Node-RED ;-)

Edit: I take it the "certificate checking by the app" was nonsense. I can't remember where I got that from. Good news.

 

[yoh-there]

Am I pushing my luck asking if you could kindly post a full example, ie using curl?

It uses SSL pinning, so one needs to try a little harder to intercept the traffic from the app.

Suitably anonymised, the end result is something like this:

curl -H 'apikey: XXXXXXXXX' -H 'x-gigya-id_token: YYYYYYY' -H 'x-kamereon-authorization: Bearer ZZZZZZZ' 'https://api-wired-prod-1-euw1.wrd-aws.com/commerce/v1/accounts/kmr/remote-services/car-adapter/v1/cars/VVVVVVVV/battery-status'

Great work! With the help of James's blog post and some behind the screens Q&A, I was able to get the whole thing working again in Node-RED. Very, very nice. Thank you again!

Been meaning to ask - does this mean the "old" API is no longer accessible to you? (I've been happily switching between them both while working on this, and not seen anything to indicate that.)

 

[yoh-there]

The old API hasn´t worked for me since 1-2 months. I got a 302 - redirect back and that was basically it. So I am very happy with your result.

mosquitto_sub output

{"type":"Car","id":"VF1AGxxxxxxxx","attributes":{"lastUpdateTime":"2019-07-18T14:52:40Z","batteryTemperature":22,"plugStatus":0,"chargeStatus":-1,"batteryLevel":78,"rangeHvacOff":104},"age":"00:26"}

"age" is calculated by Node-RED. As the TCU reliability is so-so I prefer to know how old the info is in a readable format, independent of timezone stuff.

I love this stuff. Don't understand a word of it, but I love it...?

 

[yoh-there]

Basically it means whatever can be done with the app can be done with any system.

Me, I display a few key figures in a display in the hallway. I think James uses it to automate the charge scheduling. That sort of stuff.

Excellent!

Is the updated NodeRed info on the CanZE website blog yet?

Nope. Will put it there soon.

@jamesremuscat Big thanks for this!

How do we get the keys mentioned? Not sure if I have an APK!

Maybe you can find a website that will let you download an APK from the play store somehow. I have no idea if such websites exists of course.

So when’s this new app out?

[yoh-there]

I don't think any of the devs is planning on a new app (I know I am not). This is about middleware allowing to make anything, whether it being an new app, a new scheduler, home automation integration or whatever, to work with the Renault services.

 

[jamesremuscat]

The Renault one? It's already been released in parts of Europe over the past couple of months. No idea when the UK version will launch.

 

[yoh-there]

Yeah, here (NL) and at least in France, it has been completely replaced.
