Awesome - thanks for the quick fix!
I did not fix anything 
I guess @Jonas_Enge implemented a fix, but he is probably still looking for someone to take over the project.
I’m not able to log in to the Nissan Connect Android app either, so maybe this time it’s a Nissan server problem?
Update:
Translated from Nissan Support: “A temporary problem has occurred with the Nissan EV app. We are currently fixing the error and waiting for feedback from the technical department.”
Update: working for me again now
Is it possible to get this work fot after 2019 models also. I´m willing to donate 20€.
I also want to make a donation for a Homey Nissan Connect app.
Any update: Tried to connect my Leaf (dec 2020), but unfortunately an error too.
The app works fine, but your car is not supported. Only cars made before may 2019 is supported
Ok Thanks, any outlook to have the 2020- model supported?
Since two days the homey Nissan app is not fetching data anymore. Are there more people with this problem?
Looks like Nissan updated their API. New API endpoint URL · Issue #57 · joeshaw/carwings · GitHub
Has anyone taken over this project from @Jonas_Enge and can make the necessary updates?
All ok after the last app update
Winter is coming, so I took matters into my own hands and wrote a Homeyscript that starts the Climate Controls. This means you finally get the flow card that this app is lacking. Tested October 2025 for Europe. Interested to see if this works for all of you guys….
In order for this to work you will have to manually encrypt your Nissan password to the AES standard Nissan uses. See the comments at the top of the code with for URL and the needed parameters.
// Start Nissan Leaf Climate Control
//Nissan uses AES encryption of your personal password in order to authenticate you.

return `✅ Climate start command sent successfully`;
}
// Run the flow
return await startClimate();
EDIT: Today I did not get a response in time from the car and had to run the flow card twice in order to start the climate control. I learned that Homeyscript have a max run time of 30sec, which is a bit small when talking to Nissan….So I have now made a flow which separates the “poll until wake-up complete” into a separate flow card which can be run as many times as I’d like. So I’m testing out a setup which allow for maximum 40 seconds wait (excluding the login time) before exiting the test. If someone is interested, please reply

Great work, unfortunately I got the message that vehicle did not respond in time. Probably your splitted script would solve that. Can you share it?
UPDATE: It seems that nissan has introduced case sensitive username, so make sure that you use the same as when first registered.
Anyone else having issues with the app? Has Nissan changed the api again?
@Jonas_Enge Could it be that the countrycode now needs to be hardcoded as done in the dartnissanconnect here: Use hardcoded realm · Tobiaswk/dartnissanconnect@0cabf82 · GitHub
