Dooya bi-directional protocol


I have a few dooya blinds which use the bi-directional protocol, but I didn’t find anything on the web about the protocol its using.
I currently tried to get something together with an ESP32 & a CC1101 module, but not much success so far.

Has anyone managed to get it working without using RFXCOM? (Too pricy for controlling blinds only, I don’t have any other rf devices)
