Honeywell Lyric and adding outdoor temperature to handler

I’ve posted this elsewhere but thought I’d try it here too if this is a better place to get started.
Does anyone have the original code for a Lyric wifi thermostat or a modified code that has the outdoor sensor already added to the device handler? I have the auxiliary sensor of my Lyric set up as an outdoor temp sensor. The current Lyric device handler shows the ‘outdoorThemperature’ sensor reading in the API ‘Events List’ so I know it’s being monitored. I would like to modify the device handler so it also shows this outdoor temperature reading on the thermostat handler main screen in the ST app for my location. Has anyone done this already? If I can get the original code, I can maybe add the display box and sensor input to modify the original. Is there a complete template out there? Any ideas would be greatly appreciated. Thanks.
