Smartthings integration Homekit question

I am successfully running this integration, and the devices I want to show are in HomeKit. The devices in question are a Samsung Washer and Dryer. I see that they are seen as switches (on/off) in HomeKit. But I want to add things like completion time and job state. I can see that info in the HA dashboard but would also like to see this in HomeKit as well. Is this possible? If so how is it done?
