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

[olinek2]

Hi,
I have written plugin for LG Smart AC devices. It is in it's early stage (for me it is operating in Domoticz for past few months). Finally I have finished readme .

Best regards,

Hi,
I test your plugin, it's a very good job.

I have a Banana Pi with a bananian 16.04, I had to adapt the installation :

For the dependencies :

Code: Select all

apt-get install python3 python3-dev
apt-get install libffi-dev libssl-dev
apt-get install python3-gevent python3-msgpack python3-greenlet python-gevent-websocket python-setuptools

For automatic start :

Code: Select all

#! /bin/sh
### BEGIN INIT INFO
# Provides:          perso
# Required-Start:    $network $remote_fs $syslog
# Required-Stop:     $network $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Home Automation System
# Description:       This daemon will start the Server LG AC
### END INIT INFO
 
case "$1" in
  start)
    echo "Start LG Server"
    # run application you want to start
    nohup python3 (***)/LGAC_SmartT/LGACServerNew.py &
    ;;
  stop)
    echo "Stopping LG Server"
    # kill application you want to stop
    killall python3
    ;;
  *)
    echo "Usage: /etc/init.d/lgac_server{start|stop}"
    exit 1
    ;;
esac
 
exit 0

And use /etc/init.d/(your script.sh) start


In plugin.py :

Code: Select all

sys.path.append('/usr/lib/python3/dist-packages')

I have 3 clim and i use 3 server with different port, I do not know if it's the right method, but it works




I have an error for my 3 clim, I do not know where it comes from, but it does not seem to have any consequence. If someone has an idea ?

Code: Select all

It works perfectly for me,
Thank you so much

Hi,
Very nice job !
I am also a LG AC owner, however I did notice that the reported ambiant temperatures were not accurate at all.
When my room temperature is about 21-22°C (measured with 2 different electronic thermometers): if the split is not heating, the reported ambiant temperature is about 24-25°C; and when the split is heating, it is reporting about 28-29°C ?!
Do you have the same behaviour or your reported ambiant temperatures are accurate/stable ?

[krynskip]

I try run your solution on domoticz and i have problem with link to login account. I copy link from python3 example.py and pasting to browse

"https://pl.m.lgaccount.com/login/sign_i ... country=PL" .

I see login page and enter a login and password. after i click sign in i have information about page not found.

"https://pl.m.lgaccount.com/login/iabClo ... os_type=PC"

When i copy this link to python3 example.pyi get error :

"Log in here:
https://pl.m.lgaccount.com/login/sign_i ... LGAO221A02
Then paste the URL where the browser is redirected:
https://pl.m.lgaccount.com/login/sign_i ... LGAO221A02
Traceback (most recent call last):

My qestion, What i do wrong?

[dgatien]

Hi,
I had the same issue when I was using my Google based account.
It seems there is an issue with LG accounts based on Google/Facebook accounts. Try using a LG Account based on an email and it should work (it worked for me at least).

I'm current Vera user and joined Domoticz community to have integration with LG AC, Samsung TVs and iRobot - all of wchich Vera doesn'n support :/
But for now non of this works for me in Domoticz too

@Olinek2 unfortunatelly I'm unable to send you PM, since I am new user here - I installed LGAC_SmartT as you instructed.
But after running webserver I got:

wideq.TokenError
2019-04-14T07:03:27Z <Greenlet at 0x7591c718: ac_commands_handler('AC_XXXXXX_PL', 'd27b3ec0-XXXX-XXXX-XXXX-XXXXXXXXXXXX', <Queue at 0x75ee3b20>)> failed with TokenError

So in my case format of AC Device Number is slightly different that in your example:
"????????-????-????-????-????????????": KLIMATYZATOR (AC RAC_XXXXXX_PL)

What am I missing?

[dgatien]

Hi !
Is there anybody having some LG splits ambiant temperature graphs to be shared with me ?
I have the feeling that my splits are not correctly regulating temperatures (the ambiant is rising very fast of about 3°C then stop heating, then the ambiant temp is decreasing and after a few minutes, it is heating again)

[luckymr2201]

Hi all,

I will post here the experience I got with this plugin.

It took me hours to get it work, not because of any bug it has, but because there are requirements not included to the documentation.
I had a raspberry pi running a jessie distribution and when you have this OS the latest python3 you will get it 3.4.2. Problem is that with this version when you try to start the server, you get an error message saying that "SocketKind" is not defined. This is a knwn bug from python 3.4.2 and resolved in 3.4.3.
Some people being more experts may have a simple solution for this but I ended up upgrading my OS to a newer debian distribution offering a newer python 3.5.x which then allowed me to get server running as expected.

Hopefully this will come handy to other people in the future.

Olek, your plugin is fantastic. Thank you so much for your work on it.

Starting last week I have some errors when the server is starting

Code: Select all

Hello,

I tried to install this script, evrything was great til but i can't go further than an unsuccessfull test, i do not get the "wideq_state.json" file as supposed to have.

After having widep.py file updated i run the exemple.py script, and get this :

What am i doing wrong ?

Thierry,

Once you logged in using the provided URL you should see that the resulting URL has 3 data in it. access_token, refresh_token and oauth2_backend_url
This is all that would go in the resulting json file anyway.
I suggest you simply move to the next step using the raw information from the URL that you can copy / paste in a text editor.

I hope this will be enough to get you out of trouble.

[sooper]

Hello,

I would like to inform you that the library WIDEQ has been updated, and now it is possible to change vertical and the horizontal swing

Maybe someone can adapted it to the olinek2's python plugin ?

Hello luckymr2201,
Thanks for your help, unfortunately i was not able to go next step, i created a wideq_state.json file like follow :

"{
"access_token": "1ca3e111112234e543cfada616f65ee60493d136640adc1e1f841989a7fe9cf3350594da1c6ae485e6e6e8182f4f42451d",
"refresh_token": "194be3b7596111111a5eb8ee484e180d3adb4644a63fc4f8ce9709e3f1c696fb20d1329e022d56daab51ac820893bd7",
"oauth2_backend_url": "https://gb.lgeapi.com/"
}
"
But i had the same issue when running 'python3 example.py ls' :

Traceback (most recent call last):
File "example.py", line 214, in <module>
example(sys.argv[1:])
File "example.py", line 200, in example
example_command(client, args)
File "example.py", line 180, in example_command
func(client, *args[1:])
File "example.py", line 25, in ls
for device in client.devices:
File "/root/LGAC_SmartT/wideq.py", line 474, in devices
self._devices = self.session.get_devices()
File "/root/LGAC_SmartT/wideq.py", line 465, in session
self._session, self._devices = self.auth.start_session()
File "/root/LGAC_SmartT/wideq.py", line 257, in start_session
return Session(self, session_id), as_list(session_info['item'])
KeyError: 'item'


Can't go further. Hope someone has the same issue and help

Thx.

Hi,

I am a totally newbee on Python and Raspberry Pi....

I have two LG SmartThinq AC's. I want to use them with Domoticz because the app is really slow. And I don't want to use several apps/programs to control my stuff.

I've read the wiki's.... but I really don't know where to start.
Is there a 'simple' tutorial who to install everything on a Pi in an "A to Z"-listing.

Something like:
Open Putty
Connect to your raspberry
use this command to install Wideq
use these commands to setup your connections with the AC
then do this
then do that

links to sites as :https://pypi.org/project/wideq/ drives me complety mad, because I don't know where to start.
What should I do, to install WideQ on my Pi????

after that I need to do these steps: https://github.com/olinek2/LGAC_SmartT .......
But even that is to complicated for me.... for all programmers it seems every easy, but for a newbee: a simple thing for you, is difficult for me....

So is there someone how could make a 'tutorial for a complete newbee', with very simple instructions.
Even steps that are so easy for you, not left out.... so I could copy this straight forward...

Many thanks in advance

[Melissen]

Hi, I'm a little bit further then before

Now I've got a problem at this point:
python3 example.py

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.

I've typed the url in Google Chrome and I want to log in... But the site doesn't respond.
I live in the Netherlands, so I've changed (in comparision with Poland) PL to NL... left the rest unchanged....

The url copied to CHROME... can't log in.... what am I doing wrong???

[Melissen]

Hi... Finally got some problems solved... created a new LG-account, and fixed a type-mismatch in the URL.


But now the following error occurs:
When I get to this point:
To check if the server is operating properly type: ./LGACServerNew.py.

pi@raspberrypi:~/LGAC_SmartT $ ./LGACServerNew.py
Traceback (most recent call last):
File "./LGACServerNew.py", line 9, in <module>
from gevent import monkey
ImportError: No module named 'gevent'
pi@raspberrypi:~/LGAC_SmartT $


Tried several thing to install GEVENT, but nothing works....
python3 version = 3.5.2
python version = 2.7.9

When installing several things (pip, greenlet, gevent), i see that GEVENT is installed... but it keeps giving this error
This drives me crazy.... because I'm almost at the end of this wiki

[javalin]

Good night,

I have some kind of problem when I type: $ ./LGACServerNew.py from telnet

I get this message error:

File "./LGACServerNew.py", line 99, in ac_commands_handler
if device.type != wideq.DeviceType.AC:
AttributeError: 'NoneType' object has no attribute 'type'
2020-02-09T01:28:34Z <Greenlet at 0x75909718: ac_commands_handler('nvjvbkl0-7681-22d3-34b0-0051ed5e5675: Air Conditi, 'f561e12e315a6c22dfb07ec21ewfdw20nbkjlle7427e82fe, <Queue at 0x75e55928>)> failed with AttributeError

I think I am not able to loggin in LG-Server and I cannot power on AC device from Domoicz.

Any help is appreciated.

[javalin]

Solved, just had to write the Device number "????????-????-????-????-????????????" and avoid the rest of the string

[Melissen]

Finally I boughed a brand new Raspberry Pi 3B+

Installed newest Raspbian software
updated everything...

but now I get problems at the point where I logged in to LG and put the return URL in EXAMPLE.PY

see my screenshot with a lot of errors....

example pi error.png (99.92 KiB) Viewed 12173 times

[Melissen]

WOW !!! Problem solved..... I had Raspbian Buster installed, went back to Stretch and no problems with installation....

Didn't copied the folder to domoticz yet.
I've 2 airco's and want them both installed in Domoticz, how will I do that?

After that I will copy folder to Domoticz
