pin PyCryptodomex to version 3.9.4

[tiefpunkt]

The latest release of PyCryptodomex seems to be missing the Cryptodome.Util submodule, making the SmartConfig process fail. It works with the 3.9.4 version though.

Thanks for your PR!

I don't see anything about this change in the PyCryptodome repo, and the Util module does seem to still be present in the source.

I will take a closer look when a get a chance, but feel free to add more info when available.

I did the normal installation procedures, and when starting the update, I got an error message along the lines of "no module named Cryptodome.Util". I then also did the PyCryptodome selftest ("python -m Cryptodome.SelfTest"), which failed with a similar message. Had to do it in a linux live installation, so I don't have the exact error messages anymore, sorry.

So it's definitly a PyCryptodome issue, but going back to an older version of PyCryptodomex at least let me flash my wifi plugs, so I thought I'd share that ;)

I needed to use this to make it work.

Actually the install_req script does not seem to work properly at all for me, all required modules were not installed, although it stated it did. manually installed and succeeded.

Interesting @bakman2, could you please share more details? What OS? Were any errors reported?

This was on a pi running octopi (Linux octopi 4.19.75-v7+ #1270 not sure what was done to the os specifically).

Installing, no errors reported. (sorry, i removed all directories)

Running start_flash revealed "no module Cryptodome", manually installed, restart flash, missing tornado, repeat, missing sslpkg.
Then got an error about sslpsk.git, could not write in /tmp: error 1 None. sudo, no success.

Ending up switching to root and installed all manually (forgot paho) but could flash.

I landed here because I had the same issue mentioned in #583
I can also confirm what @bakman2 is saying. I can add more details, hopefully useful:

• in smarthack-psk is mentioned that the module sslpsk is missing
• in smarthack-udp is mentioned that the module Cryptodome is missing
• in smarthack-web is mentioned that the module tornado is missing
  Further more running install_prereq.sh there was error "no matching distribution found for praho-mqtt" due to issues with certificates.
  I'm running Ubuntu 20.04

@bakman2 how did you sorted your mentioned issues out ?

And what can i do if i hav sonoffs already running?
the Flashing seems to get interuptet with my sonoff devices?
can i change the mqtt port?

I used my Pi3 and my tablet for the confim network.
I think the problem was that my Android has trustet Wifi thing...
With my old Tablet there where no problem and after few attemps its uploaded the firmware.

@kxn25 this project only supports Tuya devices, not Sonoff.
