TuyaMCU with combined RGB/CCT LED doesn't work properly

[rossi007]

Using Tuya MCU (54) and Hue Bridge Emulation (to use Alexa) results in problems, as LED-Panel requests a explicite signal to change from RGB to CCT mode via FnId26/DpId2 (0=white, 1=color). Controlling via HueBridge sends only changed RGB value to FnId24/DpID5 if color is addressed, or sends changed CCT value to FnId23/DpId4 without the light mode signal being adapted. This results in malfunction or the light.
I don't see any chance to fix that without Tasmota registering incoming type of command (color/white) and injecting previously a command to set light mode properly.
Another effect is, that dimmer function is done differently at white and color mode. Dimming white will need FnId21/DpId3 being changed as separate dimming value, whereas color dimming seems to be done in reducing the RRGGBB color value form FF to 00 each.
Using MQTT to access the given register values will result in the same "confusion".
Operating the lights and changing registers by alexa or MQTT often results in values being shortly shown in Tasmota console output, but immediately being overwritten by effects, that I don't understand. Also, operating remote control attached to Tuya module will sometimes be overwritten.
Did anybody experience similar effects ? Did I miss some proper configuration ? Or can the TuyaMCU module being adapted to the functions of combined RGB/CCT lights ?
I think just "mixing" CCT light and RBG light as RGB+X Light as given in the description is not sufficient.
... would be happy to be able to operate such lights using Tasmota, as it is such versatile, flexible and reliable ...
