Midea/Inventor (and other brand) Air Condition API

[waltervl]

Just a heads up for this new possibility for supporting the Midea AC's
The following fork/branch is supporting the *103 WiFi module (ex. SK-103 or OSK-103), using the new protocol called “8370”. For this protocol, you need provide your WiFi AP access data, MAC address of your AC WIFI module, install and run the fake cloud script.

When trying to run the plugin, I receive this error (in domoticz log):

Any ideas?

I struggled with this too it was something with loading the right crypto library and with sudo or not.
I will check toninght and com back.

[waltervl]

See https://domoticz.com/forum/viewtopic.php?t=32980
use sudo pip3 to instal: sudo pip3 install pycryptodome

Thanks! that sorted it!

Now got another issue.
I have 1 Qlima airco unit which I installed 2 years ago, and now got it running with this great plugin.

However, last weekend I installed another Qlima unit, which came with the OSK103 wifi-stick.

https://github.com/WMP/midea-ac-py/tree/support-8370

--> would this fork work, combined with the plugin.py script from alain?
So in this case I could make 2 folders in my domoticz/plugin folder, one for the old wifi stick, and one for the new wifi stick with the new fork + plugin.py.
Or does the plugin.py needs changes to work with this new brach/fork?

[waltervl]

I have doubts about that as it uses another version of the msmart Python library. So it could be that installing the special msmart library will break the old plugin.
But you can give it a try of course. Perhaps it is easier to find a 102 stick somewhere.. (Did not look for that though) Someone else in this topic did it this way.

[waltervl]

Major changes on the midea-msmart library, V3 protocol should now be supported.
https://github.com/mac-zhou/midea-msmart

So users with a 103 wifi stick should now be able to connect to Domoticz.
You can test if the example.py is working.

[Deshmir]

I recently bought a new Qlima SC5225 with wifi, and they are shipped with the a Tuya (ODZ104) wifi stick.
Took a couple of days to get it working with Domoticz, and i miserably failed. Got it connected to Homebridge instead.
So I've contacted PVG International BV and they still sell the OSK-102/103 stick: EAN: 8713508773230 for €22,50 retail price.
I got mine for € 21,27 at WarmteService.
Hopefully back to a normal situation without the annoying Tuya ****

Any news on this?
I have 2 Inventor and 1 Qlima (Midea) units over here... Should be great to use them in Domoticz!

Code: Select all

it stays on scan broadcast..
Debugging does see the 3 units as local ips, but after some seconds in debugging, i get a lot login error:

My goodness, what a meanly help over here.
in the meantime i have 3 devices supported, but what is needed to import this in domoticz?

I'm getting errors, and i'm not able to find out why:

Code: Select all

python example.py
Traceback (most recent call last):
  File "example.py", line 2, in <module>
    from msmart.device import air_conditioning_device as ac
  File "/home/pi/domoticz/plugins/midea-msmart/msmart/device.py", line 16
    def convert_device_id_hex(device_id: int):

I think i'm doing something wrong or forgot something..
could someone please explain me what i need to install from start and to use it to import the units into domoticz?
many, many thanks.

My goodness, what a meanly help over here.

The errors you are getting seem to originate from the msmart library, not my Qlima plugin which uses the msmart library. The developer of the msmart library is not an active contributor to this thread, so maybe it's the wrong place to start shouting.

Did you follow the instructions in https://github.com/mac-zhou/midea-ac-py ... /README.md and in https://github.com/NeoAcheron/midea-ac- ... asic-Usage? I'm not sure why you're not finding the ID's of the units.

[Alain]

Code: Select all

File "/home/pi/domoticz/plugins/midea-msmart/msmart/device.py", line 16
    def convert_device_id_hex(device_id: int):

points in the direction of not having the correct unit ID filled in.

When using example.py (I'm assuming that's the python script you're using in a terminal window to see if communication is there), you need to edit the python script (I'm guessing line 4) to include your found unit ID.

Thanks for answering Alain, it really frustrating me... i'm trying to figure out this for 2 days now, i'm lost..
yes i think i have readed this for 10 times or more and started again for more then 20 times..
I deleted the hole bunch, and installed again but now it left me with the login error i had before:
installed first:

Code: Select all

pip3 install msmart

(already installed 5 minutes ago)
output:

I don't have a Domoticz instance running at the moment where I can do some testing without crashing my main instance (I have 668 devices running in that). I have noticed that the msmart library has been updated a few months ago and I don't know if the problems you're having are related to that. It would be interesting to know, if it is.

I have a fresh PC sitting idle at the moment on which I want to install a new instance of Domoticz for testing purposes (I want to get some Broadlink RM4's running). I'll be looking at getting that installed within a week or two, maybe then I can also look into your problem specifically. I'm sorry I'm not able to help you out anymore right now.

It is really no problem, just thanks so far.
Glad you want to look into this.
Maybe it has something to do with the buster on rpi 4 maybe?
today i had 4 devices supported, but when using the example script it gives me that error like seen in 2 post back, so i went over again and started from start. now that login error again.. grr
i never had any issues before with other scripts this far, but this one gives me some headache, on sunday..
thanks!

[Alain]

No worries. When I have some time available, I'll look into it and post back.

[BarryT]

Hero, thanks!

[BarryT]

Any news maybe?
Still nothing works...

[Alain]

I'm sorry I haven't gotten back to you sooner. Unfortunately I've had some stuff going on and haven't yet had the opportunity to setup my test system.

[Alain]

The error occurs within the msmart part of the deal. I see you opened an issue in my github repository about it, but you should really try to get an answer from over there. I'm willing to try when I have the opportunity to test it, but can't promise anything about it.
