Use temp value status from app

I have a heat exchanger and a app installed in my Homey. The app shows a lot of different values and status. I tested Temperature Monitor but that app does not show anything from the heat exchanger which leads me to believe that the app does not report it in a format that is standard for Homey. I would like the temperatures in Homey Dash and also in my Google Nest to be actual temperatures. Is there a way to retrieve values from the app and in some way convert it so that it is reported as default in/outdoor temperature?
