Hello,

I'm in Canada and your solution was not working for me... After checking you code, I realize that the region was hard-coded to "NE" at two lines in the "leaf-python-mqtt.py" :

• Line 99 : s = pycarwings2.Session(username, password , "NE")
• Line 123 : s = pycarwings2.Session(username, password , "NE")

After replacing "NE" with variable "nissan_region_code", everything started to work for me.

Thank you for the code, great job!

Thanks for the great work you did with this program. I wanted to make your version work under py3.6, so there were a couple of changes I noticed. I'm using the py3 fork of pycarwings2 by BenWoodford.

lower case on ConfigParser in line5:
from configparser import SafeConfigParser

The mqtt message to run get_leaf_update or climate_control was not working due to the change in bytes/strings. In line 56, should be:
logging.info(msg.topic+" "+msg.payload.decode('UTF-8'))

By the same token in line 59:
control_message = msg.payload.decode('UTF-8')

I don't know if these break your version for py2 as I didn't test.

./leaf-python-mqtt.py File "./leaf-python-mqtt.py", line 191 else ^ IndentationError: unindent does not match any outer indentation level

In get_leaf_status() if logging in fails because a 404 is returned then we crash! See traceback below.

Not sure what is happening here, but running on an RPi with Jessie running the base leaf-python-mqtt works fine but after some hours (never measure fully) MQTT publication stops to a remote broker - an emonpi in this case.

The symptoms are that the process continues to log data acquisition from Nissan and publish to MQTT but the broker receives nothing. This is evidenced by local mosquitto_pub/sub working to the same remote broker from the command line and netstat showing a CLOSE_WAIT connection to the broker with one byte in the receive queue.

Not being a python expert but trying to read the paho docs I think there should be some more error checking somewhere and maybe an on_disconnect callback defined. But I am guessing.

Hello,

I've integrated your development with my OpenHab2 server and I'm now having a little problem.

When I send a request to starting heating int my Leaf, the heating starts fine in the car, but something is going wrong in pycarwings2 and leaf-python-mqtt.py crash with a "KeyError: 'cruisingRangeAcOff'" after its 60s wainting.

The whole trace is :

After that, "leaf-python-mqtt.py" need to be restarted if I want to do anything else.

One thing worth mentioning : I'm in Canada and therefore my region is NCI.

Thank you!

Hi,
We've been using this script quite successfully, but in the last week or two it has stopped working and gives and API error. I see filcole has a more recent pycarwings2, but we can't successfully use it with the examples, have you managed to run leaf-python-mqtt.py recently?
Thanks

Hi Folks
I'm getting a URL error when I try running this script on my emonpi. I've pasted the debug output below, having removed my Leaf user/pass, which we know works on the 'My Leaf' android app.

What am I doing wrong, please?!

Cheers
Tim

I suspect there may have been another API change recently, there was an update on some third party apps yesterday stating they were updated for the "new Nissan API".

I followed the install instructions and installed fresh today.

Hi!

First off, great work in buidling a script that integrates with mqtt. Just the kind of home automation i enjoy! Now for the problem.

I have configured everything correctly it seems, as the work on getting values start (it didn't earlier as i did the same error as some others, using the mail adress instead of username for login), but it seems to me the output values we receive is strings and not ints.

Hope you could help shed some light on what might be causing this.
