For an AZE1 new-shape LEAF, you could try my solution or @Sriracha’s fork. Not a full integration, but works well here.

I have this problem again.
I resolve in the same way of previous time. I edited the file
homeassistant/lib/python3.8/site-packages/pycarwings2/pycarwings2.py
at line 125:
headers={"User-Agent": "pycarwings2/2.10"}
with this:
headers={"User-Agent": ""}

@filcole Hi mate, it looks like the Nissan Leaf Integration has been borked again with the latest core-2021.5.5 update. Would you be able to take a look at it please?
Logger: pycarwings2.pycarwings2
Source: /usr/local/lib/python3.8/site-packages/pycarwings2/pycarwings2.py:164

@andbad has a fix in the above post.
Thanks etc. 
Thank you! This fixed it.
For people using Container based install (OS, supervised, Docker), the file path is:
/usr/local/lib/python3.8/site-packages/pycarwings2/pycarwings2.py
For supervised and Docker, use this command to get into HA Core Container to get at the file:
docker container exec -it homeassistant bash

I have the same problem using Home Assistant OS on a Raspberry Pi with core-2021.5.3
Been struggling to get to file. Is there a way to edit the file on my setup?
I use the Leaf data to always charge the car to 70% overnight in low tariff. If I need the car, I set a departure percentage, day and time and the automation will top up the car if needed and activate climate control just before I am leaving.
I just realize now how much I love this automation, now it is broken.
Try this for HA OS (the second set of steps)
Then inside HA container, use the path I posted above with Linux CLI editor of your choice (nano or vi)
Thanks! I’ll dive into this when I have enough time, probably Tuesday.
Let you know.
Sorry, i have home assistant based on linux on a vm in proxmox.
I cannot find /usr/local/lib/python3.8/site-packages/pycarwings2/pycarwings2.py even it’s the fil I see in the log.
I user the terminal extension to do ssh, is it the issue??
Kindly
Gregori
My integration was working fine, I was using some Node red automation and everything was perfect
but since three day ago the Nissan Leaf entity vanished and my dashboard show instead
Entity not available: sensor.leaf1mail_charge (and etc…)
Looking at the log I have some error
2021-05-22 17:32:54 ERROR (SyncWorker_9) [pycarwings2.pycarwings2] carwings error INVALID PARAMS: 404

I didn’t touch the config since but here it is

See my answer above. Nissan change something in its server.

Sorry. ok thanks.
I can see the file using SSH but It’s seems like nano is not installed, how can I make the change?
Try vi rather than vim

Thank you!
I created a (ugly) card for my wife’s leaf, but I would like to add a text like “last check: 10 min ago” or whatever.
any idea how to implement that? or then only showing the late update date?
for example how could I display binary_sensor.leaf1mail_charging_status sub state (updated_on) formatted like HH:MM ?
At the linked page it was suggested to use the Portainer add-on to access the homeassistant container. That turned out to be surprisingly easy.
When inside the container I used VI to edit pycarwings2.py, using the path provided by wyx087 and the change provided by andbad.
My car is connected again, thanks guys!

I implemented this myself today.
Created a sensor with the charge level and time of last update:
leaf_charge_and_last_updated:
friendly_name: "Laadniveau + tijd update"
value_template: "{{ states('sensor.leaf1stee_charge') }}% om {{ as_timestamp(state_attr('sensor.leaf1stee_charge', 'updated_on')) | timestamp_custom('%H:%M') }}"
At this moment it gives "26% om 22:06" as a result.

would you consider sharing the whole config ? mine is awful
Sure, what exactly are you interested in?
I started with the picture-elements card that michel72 posted in this topic.
Then I tweaked the cars range a little bit, to give it a more realistic range.
leaf_range_ac_realistic:
friendly_name: "Leaf Range AC real world"
icon_template: "mdi:speedometer"
unit_of_measurement: 'km'
value_template: "{{ (((states('sensor.leaf1stee_range_ac') | float) | multiply(0.8)) | round(0)) }}"
And I combined the current charge level with the last updated time within one sensor:
leaf_charge_and_last_updated:
friendly_name: "Laadniveau + tijd update"
value_template: "{{ states('sensor.leaf1stee_charge') }}% om {{ as_timestamp(state_attr('sensor.leaf1stee_charge', 'updated_on')) | timestamp_custom('%H:%M') }}"
I changed the picture to this one, because thats how my car looks like:
I put the cars data on the left side of the card and the charger data on the right side.
This is the whole picture-elements card:

The buttons outside the picture-elements card are all input_booleans for the Node Red automation, which turns my Zappi charger on and off, when I think is best for the battery pack and my wallet.

nice job thank you ! I’l try that, seems much better than mine!
I already have a nice node red integration but my picture-elements card is pretty bad!
thanks again
