I'm trying to implement one more device the same way as I've done this one. It is Aubes smart switch with new chip bk7231n (module wb2s). The device config is written, but the integration says me that it can't connect (when I'm trying to add it). Is it well know issue? Could you give me just a start point/idea for investigation, please?

[make-all]

#522 is the start point. There are many things that can cause connection issues. Newer devices are likely to be protocol 3.5, which is more fussy about configuration, or you may even have one of the first devices with a newer protocol (though I'd expect Tuya to move to Matter next rather than push on with yet another version of their proprietary protocol)

[realdimik]

After the last tuya-local update the device was disconnected with "migration problem".
I removed it and tried to add it back, but snt957w_de_cbu_temp_humidity is not suggested as an option any more :(
(the device file is present and looks correct)
Could you help me with that?
