Hello, I have successfully ported the cloudcutter exploit to the RTL8720CF and flashed my Carro ceiling fan with openbeken.
It's a TuyaMCU ceiling fan with a light attached to it, with an independently controlled "white" and "warm" LED. The fan also is reversible and has an oscillation mode. There apprently is a timer based on the DPIDs but nothing I could control from the remote and I'm not sure what it does.
This is my configuration I have hacked together: (autoexec.bat)
I am not totally happy with it, since Fan Speed is an enum but really it should be a value between 0 and 10, I just couldn't figure out how to get it working.
For reference here is the tuya local configuration which matches what I have: https://github.com/make-all/tuya-local/issues/930
and also the device.json from cloudcutter:
EDIT: I tried cleaning up my script, now it seems like it broke the UI. I can't load the site without getting connection reset. I also can see that it thinks the fan is a dimmer rather than a fan on HomeAssistant:
