Tinytuya step by step made simple

[crsengineering]

Hi to all!
I am newbie about Tuya and tinytuya.
How can I replicate tinytuya with simpler instructions? I correctly connect to a v3.4 tuya device but I need to do it with simpler instructions due I need to control it through C.
Is this possible?
Thanks.

I'm not sure what you mean by "simpler instructions." Tuya devices are complex and v3.4 requires AES-ECB encryption, HMAC-SHA256 digest, and a 3-way handshake at the start of each connection to exchange the session key.

Ok, without bother you why I am trying to do this, I mean if I can use several (simple) python instructions to connect to tuya devices instead using tinytuya libraries.
Using tinytuya I just need to supply IP address, version, DeviceID and key, I would like build and manage tuya devices step by step.

Hi @crsengineering - I think what you are looking for is in the XenonDevice class code:

tinytuya/tinytuya/core/XenonDevice.py

Line 192 in 3fa3870

class XenonDevice(object):

and you can use tools like ChatGPT to help extract out just a simple step by step representation.

But as @uzlonewolf notes, the protocol is complex which is why we built the library to help abstract the complexity. You can see the notes @uzlonewolf put together on the protocol here: #260
