Failed to add device: Failed to get status (Failed to get status: unpack requires a buffer of 20 bytes)

The problem

Im trying to add AUBESS Mini Smart Switch. Some time ago i did it successfully by the protocol 3.3. Now Im stuck on adding form; I check local ID of device (by command tuya-cli wizard), then in HA integration try to add new device. Device automaticly shows in list, I`ve select it. Then enter name and local key. Submit. 3.4 protocol return "User input malformed" without any awayt. If i select 3.3, it shows loader and error like "Connection to device succeeded but no datapoints found, please try again. Create a new issue and include debug logs if problem persists.".

All I see in logs is:

This error originated from a custom integration.
