Unable to discover the device

[fra87]

Describe the bug
I'm trying to connect to a Mi Wifi- Range Extender Pro, but every time I try to use the miiocli tool it replies "Unable to discover the device"

Version information (please complete the following information):

• OS: Windows 11, but tried also with Debian 12
• python-miio: miiocli, version 0.6.0.dev0

Device information:
Can't find it since the program always tell "Unable to discover the device

To Reproduce
I downloaded the latest github version (as of 9 August 2023), then created a virtual environment and activated it (python -m venv .venv then .venv\Scripts\activate.bat), installed poetry inside (pip install poetry) and "compiled" the program (poetry install). Finally I run the commands in Console output.

Expected behavior
My mi device is discovered and I can get the connected devices.

Console output

The discover command is not successful, but finds the repeater at 192.168.2.33:

(.venv) D:\programming\Python\python-miio>miiocli discover 
INFO:miio.miioprotocol:Sending discovery to <broadcast> with timeout of 5s..

WARNING:miio.discovery:Handshake failed: Unable to discover the device 192.168.2.33

The cloud command finds the device and token, and shows a strange localip (my home network is 192.168.2.x):

(I masked some info I thought was sensitive; if you need something just ask)

Then if I try to get any information I get the exception:

miio.exceptions.DeviceException: Unable to discover the device 192.168.2.30

I tried with 192.168.2.30, which is the IP my router associates to the device, 192.168.2.33, which is the IP returned by discover, and 192.168.1.194, which is the IP returned by cloud. I also tried different commands, such as wifirepeater status or configuration, found in #1151, but with the same result.

Note: I tried using the --debug flag, but the result was:

Usage: miiocli device info [OPTIONS]
Try 'miiocli device info --help' for help.

Error: No such option: --debug

Thank you for any help

I tried reproducing the same with the latest version on github (commit 9b17d90) which includes the fix #1812, but I get the same results.

Again, but I don't know if it is normal, if I check with miiocli cloud the IP I get is "strange" (it is not in my home network subnet)

[fra87]

Just a question for the other people having the same device. Is it ok that a different IP is reported?

I was trying to see if it was possible to change the device's IP address, but was not able to find anything, and I'm afraid this can be linked to #422

[fra87]

Nope, that's not linked to that issue. Today I switched IP so I'm in the same network but I don't get any improvement.

I noticed that in my home router its IP is 192.168.1.195, while the one reported from the cloud is 192.168.1.194.

Honestly I have no clue on why this happens and/or how to properly debug it. Why cannot I communicate with it? Is this a common issue with the repeater v3?
