Is there any documentation about the Tuya API that this library is using?

I have just created a pull request to improve how this library is working with brightness ( https://github.com/PaulAnnekov/tuyaha/pull/21 )

I have spend some time debugging the system and finding out how Tuya API is working.

I've tried to find some kind of documentation for this API, but I can't find any.

As I see from the code this library is using several endpoints:

• https://px1.tuyaus.com/homeassistant/auth.do
• https://px1.tuyaus.com//homeassistant/access.do
• https://px1.tuyaus.com//homeassistant/skill

There is homeassistant in the url, so I assume that these endpoints were created especially for this library. At first I thought that this server px1.tuyaus.com is just a middleware made by the author of this library to proxy requests to the officcial Tuya API, but whois info does not confirm this.

From what I saw during playing with this API I think that the official TuaySmart app is using some other API (Using this API I wasn't able to set the exact same values of the brightness that I can set in the official app).

So, my question. What is this API and is there any official documentation for it?

That's what I know:

• There was a guy who was working for Tuya Inc and developed original python library. He also developed integration with HA
• He has left the company https://github.com/home-assistant/home-assistant/issues/19074#issuecomment-471370475 ~1 year ago
• This API is quite unstable and it was broken once https://github.com/PaulAnnekov/tuyaha/issues/3#issuecomment-523656935
• I never see any docs about it, so it's unofficial
