Re: Nissan Leaf Plugin

Looks like Nissan has disabled the API after security researchers disclosed a vulnerability today: http://www.usatoday.com/story/tech/news ... /80882756/

That means this plugin won't work, at least not until they re-enable the API and I'm able to (hopefully) make it work again. I'll keep an eye out and update when I learn more.

Nissan Leaf Plugin

Spent most of yesterday drooling over the Leaf's big brother, the e-NV200. (Combi, not Van)

It's the Nissan electric version of the Peugeot and Renault diesel cars I've driven for 10+ years.

Does this plugin use the new EV Connect system or the old CarWings system?

Re: Nissan Leaf Plugin

I thought EV connect was just the new name for carwings?

Computer says no.

Re: Nissan Leaf Plugin

Not sure.

Some pages/brochures mention CarWings, others EV Connect.

Re: Nissan Leaf Plugin

I think the only difference between CarWings and NissanConnect EV is branding--they're the same thing. There have been two different APIs for this multi-named service: the first one was XML-based, and clunky. I don't think there was any correlation between the two names and the two APIs, but I could be wrong.

I wrote the plugin to use that original XML API, via the pycarwings library. A couple weeks ago, that API stopped working, so I rewrote the plugin to use the newer (and much better, IMHO) JSON-based API. Now, that API has also been shut down, presumably temporarily while they address the security vulnerability.

I really, really, really hope that Nissan does the right thing to "fix" the API, in that they only add authentication checks, leaving the API available to properly-authenticated 3rd-party applications. There could really be a rich ecosystem of third-party applications around the Leaf, including this plugin. Such an ecosystem would only make the Leaf more attractive to potential buyers.

Re: Nissan Leaf Plugin

Dusty,

I've been chatting with a chap on SpeakEV today - he runs https://evhighwaystatus.co.uk/

He's added the ability to control AC, start charging and get the battery status - and it is working now.

Could you look at https://github.com/ScottHelme/CarWingsI ... import.php which is where he got the core idea from; Scott Helme is happy for people to use his code to build their own systems.

See if that's any help to you getting the plugin working whilst Nissan is down / in case Nissan do close up the API?

Peter

Re: Nissan Leaf Plugin

howartp,

That's a good idea; looks like they're screen-scraping the Carwings/NissanConnectEV web site, treating the actual website as an API.

Yep, there's a path forward using this approach. I've been hoping that Nissan would soon release a tweaked version of the disabled REST-based API, though, which would make the screen-scraping approach unnecessary. I've found screen-scraping approaches to be generally brittle, since Nissan (for example) could change the design on their web site at any time, but if we don't hear an update from Nissan soon, I'll give it a shot.

Thanks for the pointer.

Re: Nissan Leaf Plugin

Thanks for heads up; my App Store hadn't noticed it until i checked.

Is the plugin ok or does it need work?

Re: Nissan Leaf Plugin

I tried re-enabling it, and I still got HTTP 404 errors from the server in the Indigo event log. I tried USA, Canada, and Europe servers, but all returned 404s. I'm encouraged that Gusten's is working, but I'm not sure how!

Might have to proxy again to see where the app is connecting, because the new app does clearly work.

Re: Nissan Leaf Plugin

I think Gusten meant the app is working, not the plugin.

I just jumped on my indigo remotely and that's failing as you say.

Re: Nissan Leaf Plugin

I've got an updated version of the plugin that seems to be working with the new 'secure' API. The encryption in the new API requires use of the "pycrypto" library, which I don't think I can bundle into the plugin because: 1) it compiles code upon installation; and, 2) well, it contains crypto, which is, of course, naughty.

So, before using the new version, you'll have to install the pycrypto library manually, using the terminal. The following command worked for me on the two machines that I tested with:

Code: Select all
sudo easy_install-2.6 pycrypto


After installing pycrypto, you should be able to update from GitHub per usual. At least, this worked for me.

Give it a shot and let me know how it goes.

Re: Nissan Leaf Plugin

Well, of course, after I post the plugin update here, I go back to my indigo log and notice what seems like a "timeout" error using the new API: error response said "NO MACH VIN".

But, then I restarted and everything seems to be working fine for quite a while now. So, YMMV? Let me know if you have trouble.

Re: Nissan Leaf Plugin

Ok, I've installed the update, deleted by current 'Leaf' device and edited and saved the config dialog. (I notice you've changed the Region parameter - I had to reselect that).

I'm getting tonnes of:

Code: Select all

I then enabled debug, which gave me two lines of debug then promptly stopped attempting any communication with CarWings:

I've had nothing from the plugin in my log since then (12 minutes ago).
