RF Transmitter not working in ESPHome

[johnsmith8439]

KCS firmware works with some RF devices. I then install Tasmota, it can receive the signals in Tasmota but I have no idea how to receive or send signals from Home Assistant to control the devices.

For example, this RF fan has speed 1 (0x15C3D5), speed 2 (0x15C3D9), speed 3 (0x15C3D4) and off (0x15C3D2).

Code:
