Hi Jason and welcome to the right site… 
On this page you can post a request to create an app.
If no one is willing to write an app, most apps are programmed by Homey users in their spare time, then there is still the possibility to use the community Home Assistant app programmed by @RonnyW. Afaik, you need also the MQTT Client and the MQTT Hub apps. If there are any problems with the HA entities, Ronny is a very active, helpful user and programmer.
