Authentication failed when running midea-discover

[GrabkaMan]

Hey,

I've been trying to add my Rotenso AC unit for few days now with different options and can't add it to HA.

The biggest issues - I think - is when trying to run midea-discover
This is my response:

+The second devices data

The thing is when I run the midea-discover the second time I get different TOKEN and KEY. The rest of the data is the same.

Any ideas why this happens?

I've also tried using my credentials, but the same error happens

The token or key has time information, so each request will be different.
token and key is reusable, just choose one, no need to repeat requests for.

I forgot to explain the issue authentication failed😂
Midea has 2 forms of udpid, it is not confirmed which one is suitable for the device, so it will be requested 2 times and 1 of them will fail

midea-msmart/msmart/scanner.py

Line 57 in f07e760

for udpid in [get_udpid(self.id.to_bytes(6, 'little')), get_udpid(self.id.to_bytes(6, 'big'))]:
