AcuRite 592TXR Temperature Humidity sensor and LilyGo

I just purchased a LilyGo 433mHz board and loaded OpenMQTT via VS Code and PlatformIO and everything is working as expected (except maybe the limited range). However, the temperature reading sent to HomeAssistant via MQTT is in Celsius and I would like to display the temperature in Fahrenheit. I could probably convert the display unit in HomeAssistant but would rather make the change at the source from within PlatformIO and recompile and download. Since the source code is huge, maybe someone can point me to the correct config or ino file? Thanks
