Crypto package not found

[mail4reset]

After upgrading from v1.2.13 (meross_iot==0.4.6.2) to v.1.3.0 (meross_iot==0.4.7.0) the integration stops working with the error detailed in the log. After googling for a while I found the Crypto package seems to be deprecated. I checked in my venv and found:

(homeassistant) homeassistant@raspberrypi:/srv/homeassistant $ pip list | grep crypto
cryptography                 42.0.5
pycryptodomex                3.20.0

So I managed to bypass this problem by changing the line 4 of the file /srv/homeassistant/lib/python3.12/site-packages/meross_iot/controller/mixins/encryption.py from from Crypto.Cipher import AES to from Cryptodome.Cipher import AES. Now the integration is working fine.

Hi @mail4reset ,
good catch. This is an error on the low MerossIot library, which missed the correct dependency import within setup.py. I'll check on that and report back when a newer beta version is ready for you to test.

Hi @mail4reset ,

v1.3.1 should fix the issue. Can you please test it and report if working as expected now?

Hi Alberto,
v1.3.1 solved the issue.
Thank you very much for your quick answer!
