Connection to TP-Link LTE router fails with MR-6400 v5

The problem

Hello,

Login to TP-Link LTE router with the tplink_lte core integration fails at login time, preventing the associated SMS service to be instantiated.

Declared issue here with HA core 2022.6.6 but actually never worked even with pre-2022.
My TP-Link LTE router is MR6400, running firmware v5.

Error doing job: Task exception was never retrieved

  File "/usr/src/homeassistant/homeassistant/components/tplink_lte/__init__.py", line 122, in _setup_lte
    await _login(hass, modem_data, password)

Hello,

Same issue here with Home Assistant 2022.8.7 container and TP-Link Archer MR600 V1 router.

Info on the TP-link:

Firmware version: 1.3.0 0.9.1 v0001.0 Build 210608 RC.66100n
Hardware Version: Archer MR600 v1 00000001

The logs:

Is it possible to correct this please?

Hello @Michsior14

Could you look for errors please?

[Michsior14]

@Rathorian Unfortunately I am not a maintainer of tp_connected and don't have equipment to test it. Anyway I can see nn being not always initialized before the debug is done (https://github.com/andtos90/tp-connected/blob/master/tp_connected/tp_connected.py#L115). Adjusting this will probably not fix the core issue of not getting response, but at least will make sure the logs are a bit more helpful.

I will try to open the PR in the library during the weekend if no one will do it before.

[Rathorian]

@Michsior14

Sorry, I mistakenly thought you were keeping the embed.

I admit I don't know Python, if you already have the possibility of doing a PR to solve this problem, that would be super nice. Thanks to you

I will try to find the maintainer and see with him for the rest.

Hello @andtos90

Would you be able to look at the problem above please?
I would love to be able to use it....

Thanks

I'm also looking forward on a solution since I got a brand new TP-Link LTE router. I have the same problem.

I have the same issue with tp-link TL-MR6400

Running on RPi4:
Home Assistant 2022.11.4
Supervisor 2022.10.2
Operating System 9.3
Frontend 20221108.0 - latest

[ausfas]

Who is the author of this integration, have we not got a resolution to this issue as I have order to link LTE router MR6500 and hoping this to work

[Maco65]

@ausfas - I support this question/request.
In the integration github page there is no owner (the field in manifest.json) is empty.
The oldest history of this integration shows that @balloob has "Embed all platforms into components..." on February 2, 2019. It also shows that @bdraco has added loggers to manifest.json on January 28, 2022.
Do not know what can I do more to get this resolved....

[Maco65]

What can be done if there is no response to the issues registered ?
Should we make a request to remove this integration fro the list since it does not work?
On the Integration page of HA it says that it is used by 24 active installations - which probably means that it is installed in such number of installations but if it working ?

[albenex]

same issue here with MR500.
