This issue may be related to Protocol 3.4 session key negotiation. See #284 for tracking the implementation of this feature.
The T2070 (E20 3-in-1) is suspected to require session key negotiation for proper communication.

As I have a T2070, I am open to assist with some testing.
If your code is ready for some testing on the T2070, let me know!!

Here's the next beta release.
This should give us a solid foundation for adding these new robovacs. Could you let me know what pointers you need to get started?

And now?

[marcelhoogantink]

@damacus What can I do now, when no Tuya device is found?

[marcelhoogantink]

Debugged in tuyalocalapi.py when adding a device:
