Python Plugin: LG Smart AC (SmartThinQ) Topic is solved

[luckymr2201]

Hello majki,

Due to a technical issue I had with one of my heat pumps module, one was replaced today. I used for the last 2 years the v1 api but once new module was added to my mobile phone application, it does not appear in my updated list of modules. So I made the assumption I may need v2 api for this new module.

I installed your plugin but I am facing an issue which apparently already happened to someone on this thread:


pi@Pie4B:~/domoticz/plugins/domoticz_lg_thinq_plugin $ python3 example.py -c FR -l fr-FR
2022-03-07 17:44:38 ERROR [wideq.example] No state file found (tried: '/home/pi/domoticz/plugins/domoticz_lg_thinq_plugin/wideq_state.json')
Traceback (most recent call last):
File "example.py", line 268, in example
with open(STATE_FILE) as f:
FileNotFoundError: [Errno 2] No such file or directory: 'wideq_state.json'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "example.py", line 382, in <module>
main()
File "example.py", line 378, in main
ret = example(args.country, args.language, args.verbose, cmd=args.cmd, args=args.args)
File "example.py", line 273, in example
raise IOError
OSError

Obviously the file wideq_state.json does not exists yet so this error is sort of expected but when this last happened to someone you made a modification to your plugin.

Can you please assist me so I will be able to run example.py and check if my missing device appears with the V2 api ?

Many thanks in advance.

Regards.

Please note, that you must have LG account different than google

[luckymr2201]

Thank you superprzemo. This is working now. As expected my new module is a v2. So I will have to use a hybrid config until there will be one plugin supporting both v1 and v2

Since yesterday I receive errors like:

Maybe it's caused by LG outage, or caused by something else?
Issue seems gone for a while when I disable and enable the hardware (plugin) in Domoticz.

*edit* hm the last shown error keeps coming back, can't controle the AC anymore, when I want to switch it on:

Hi gvrgvr!

First, make sure that you are using latest plugin version (git pull). Second, open LG ThinQ app on your smartphone and if there's new license to accept, please do it. Sometimes when we have API errors like this it's caused by changes in license and it have to be accepted with the app. No problem when you are using app only, new license dialog shows up with app start anyway. For this moment, our plugin is not aware of any license changes and throws errors, because it cannot connect to API.

Also, I've sometimes seen API errors when I was adding heat-pump feature (with other user's installation), but with my own configuration (AC only) there was no such an API errors. It appeared randomly, I don't know the real reason of this for now, but I hope it is just license thing in your case.

Hi Majki, yesterday I checked the LG app, there was no licence to accept, today I checked again, surprise, there's a new license to accept!
That caused the errors, it's working again, thank you for the help!

[majki]

Guys!

I have now pushed new version with heatpumps integration. Just pull last version from github and enjoy!

Many thanks for @superprzemo for supporting his wideq file (yes, integration was made remotely )

[gert1956]

Did try to install the original plugin on Ubuntu. It worked for some time. (Olek (Olinek2) and the fork of Herman (heggink) as well)
Now I get an error from Domoticz on restart
'PluginSystem: Failed dynamic library load, install the latest libpython3.x library that is available for your platform'
Any suggestions?

This plugin uses the wideq modified library. This plugin contains some modified functions from the domoticz-mirobot-plugin library. This plugin contains some modified functions from the domoticz_daikin_BRP069A42 library. LG AC Smarthing Unit control for Domoticz
Before installation plugin check the python3, python3-dev, pip3 is installed for Domoticz plugin system:
sudo apt-get install python3 python3-dev python3-pip. done
Make sure you have libffi and openssl headers installed, you can do this on Debian-based systems (like Rasperry Pi) with:
sudo apt-get install libffi-dev libssl-dev. done
Also do note that the setuptools version is too old for installing some requirements, so before trying to install this package you should update the setuptools with:
sudo pip3 install -U setuptools. done
Install all necessary libraries for LGACServer.py:
sudo pip3 install gevent msgpack-python greenlet. done
Install [LGAC_SmartT] by typing something like:
$ git clone https://github.com/olinek2/LGAC_SmartT done
$ cd LGAC_SmartT done
$ sudo pip3 install -e . done
Update region data inside wideq.py file. For US it looks like this:
GATEWAY_URL = 'https://kic.lgthinq.com:46030/api/common/gatewayUriList'
APP_KEY = 'wideq'
SECURITY_KEY = 'nuts_securitykey'
DATA_ROOT = 'lgedmRoot'
COUNTRY = 'US'
LANGUAGE = 'en-US'
SVC_CODE = 'SVC202'
CLIENT_ID = 'LGAO221A02'
OAUTH_SECRET_KEY = 'c053c2a6ddeb7ad97cb0eed0dcb31cf8'
OAUTH_CLIENT_KEY = 'LGAO221A02'
DATE_FORMAT = '%a, %d %b %Y %H:%M:%S +0000'
For Poland and probably rest of EU like that:
GATEWAY_URL = 'https://kic.lgthinq.com:46030/api/common/gatewayUriList'
APP_KEY = 'wideq'
SECURITY_KEY = 'nuts_securitykey'
DATA_ROOT = 'lgedmRoot'
COUNTRY = 'PL' done
LANGUAGE = 'en-EN'
SVC_CODE = 'SVC202'
CLIENT_ID = 'LGAO221A02'
OAUTH_SECRET_KEY = 'c053c2a6ddeb7ad97cb0eed0dcb31cf8'
OAUTH_CLIENT_KEY = 'LGAO221A02'
DATE_FORMAT = '%a, %d %b %Y %H:%M:%S +0000'
To do that just open it in nano and save (Ctrl+X. yes and enter): nano wideq.py
Authenticate with the SmartThing service to get a refresh token by running the WideQ example script.Run this in the wideq directory:
python3 example.py done
The script will ask you to open a browser, log in, and then paste the URL you're redirected to. It will then write a JSON file called wideq_state.json. done
Look inside this file for a key called "refresh_token" and copy the value.
We also need an AC Device Number. To obtain it run:
python3 example.py ls done
Device number looks like that: "????????-????-????-????-????????????": KLIMATYZATOR (AC Rxxx_xxx_xx)
After obtaining this two values just put them inside LGACServerNew.py file at default parser arguments.
parser.add_argument('--acDevNum', type=str, help='AC Device Number', default='copied dev num') done
parser.add_argument('--token', type=str, help='Refresh Token', default='copied token') done
Make it executable: sudo chmod +x LGACServerNew.py done
To check if the server is operating properly type: ./LGACServerNew.py. done
It will start operation. Open another terminal window, log in, navigate to 'LGAC_SmartT' folder cd LGAC_SmartT and run testServer.py file:
sudo python3 testServer.py.
You should observe communication between this two applications.
To run server automatically the service has to be made. Paths in line ExecStart=/usr/bin/python3 /home/pi/wideq/LGACServerNew.py is for python path (use: which python3) and second phrase is for location of LGACServerNew.py path. Make service file in systemd: sudo nano /lib/systemd/system/lgac_server.service. Paste this text with path modification: done
[Unit]
Description=LG AC Device Server
After=multi-user.target
[Service]
Type=simple
ExecStart=/usr/bin/python3 /home/pi/LGAC_SmartT/LGACServerNew.py
Restart=on-abort
[Install]
WantedBy=multi-user.target
Press Ctrl+X, hit Y to save and enter.Then set privilidges: sudo chmod 644 /lib/systemd/system/lgac_server.service. Reload daemon and make service running, then check a status of service: done
sudo systemctl daemon-reload done
sudo systemctl enable lgac_server.service done
sudo systemctl start lgac_server done
sudo systemctl status lgac_server done
Status should look like this:

[gert1956]

Its related to 3.10 of python; some stupid string compare
I'll repair that and create a fork.
First have to find out how to do that.
I am a retired seasoned professional programmer; not in python but in many other languages.
With a little help from my internet friends I'll probably manage.

[gert1956]

The Domoticz Beta solves the problem. Its still not working, but I'll learn Python first before further investigation

Hi All,

Got a question: after installing the plugin (from github majki09), executing the example.py, getting the wideq_state.json with api version 2. Restarting Domoticz, adding the new hardware; I got an error: wideq_state.json file missing or corrupted

[waltervl]

So you have a wideq_state.json file in your plugin folder?
Is it readable for the user running Domoticz? Perhaps you have to change the permissions.

[smedest]

Hi,
yes, I have a wideq_state.json file. it has owner Domoticz.

Tried the api V1 version as well, no luck.

wideq_state.json:

Indeed outdated. Try the dockerized Domoticz version, see wiki https://www.domoticz.com/wiki/Synology

[majki]

Hi @smedest.
I think I've found the issue - you have "/var" folder for your plugins and this path is not covered by the plugin yet. I've posted a reply on your github issue:
https://github.com/majki09/domoticz_lg_ ... 1237701750

Also thanks for you @waltervl for trying to help - I have missed last post from this forum. And I really prefer people report issues on github, rather than domoticz forum, so

if you found any issue for this plugin, please report this on github
https://github.com/majki09/domoticz_lg_ ... new/choose
thanks

We can still discuss about plugin itself here on our best domoticz forum

The LG ThinQ plugin works perfectly with my LG Airconditioning unit. Happy that I can control it with Domoticz! Thanks; great work.

The LG ThinQ plugin works perfectly with my LG Airconditioning unit. Happy that I can control it with Domoticz! Thanks; great work.

Now I have issue's with this LG ThinQ plugin. When I enable and configure the Plugin, everything is working OK. But after a few days, when I check again, it says that the session is expired. At that point I need to delete the wideq_state.json and reinitiaze the plugin, After that, it is working again, but it looks like that there is a problem with my credentials. Any idea?

Edit-> I did some additional testing; but it seems like I am able to control the LG Airco for around 2 hours within Domoticz. After that I get an error message that I am not logged in anymore and I get all kind off errors. The only strange part is; I do not have to delete the wideq_state.json file, only a restart off Domoticz is sufficient to get it going for again 2 hours. I find this strange; because this would suggest that the Plugin by itself is working OK; could this be a bug within Domoticz? Any help is appreciated.
