Z-Uno Analog Pressure Sensor Project: need help with Edge Driver

I’m new to the Z-Wave.me Z-Uno board. I’m currently trying to use it with a 3-wire 0-5V automotive style pressure sensor, which is using the board’s ADC1 input pin. It’s connecting fine to the hub and got it to communicate using a generic Z-Wave Edge driver, though the values are not correct because the driver wasn’t created for this specific application. I have no familiarity with creating my own driver and am a little bit stuck on where to go next to get my project functional. I’m hoping someone has been down this road before and can help guide me. Thanks!
