I love my 3 emporia vue's (pool house, garage and main house).
I looked at the python code. it looks like it authenticates and then just pull json strings with the data. That should be possible to move completely into a native hubitat app.
I won't have time to do anything with it (working in a startup so every living hour is spent on the company), but hopefully someone else can.
the vue is excellent, highly recommend it. Installs into the fuse panel, hook up amp meters to each fused circuit, label the circuit and voila, you have detailed power consumption graphs. Highly recommended. The device sells on amazon for about $100-150.
