Tuya endpoint does not return all owned devices

Hello everyone,
I have an aroma diffuser integrated with TuyaSmart that I can view and control without problems even with Google Home. I know that this type of device is not included in the Home Assistant integration and for this reason I wanted to write the necessary code myself. Unfortunately I realized that the endpoint “https://px1.tuyaeu.com/homeassistant/skill
does not return all my registered devices in fact his answer is:

"{'header': {'code': 'SUCCESS', 'payloadVersion': 1},
     'payload': {'devices': [], 'scenes': []}} "

How come this happens?
Who manages that endpoint?
Is the endpont filtered a-priori?
Why not let everything pass and then leave it to the HA modules to select the configurable devices?

I have the same problem, did you solve it?

Hello, this problem has been solved or not? I have same problem.

Best regards
Philippe
