setup an ESP32 DEV using a CC1101 for receiving/transmitting RF signals to the old hunter fan. The controller board inside is stamped "Rhine UC7042T" and the encoder inside uses a HT-12E. all functions appear to work with the ESP buttons. I used google AI to assist in the code:

my dip switch settings may differ from yours, so the code "001111111101" for example would likely have to change.
