Cetetherm heat interface unit Pioneer P1 not integrating

[ahammas]

Hi! I have the Cetetherm heat interface unit Pioneer P1 with myUplink connected services. I'm trying to integrate it to HA but I get error 500 Internal Server Error when I press 'link account'. Their own app is rubbish for presenting statistics so I was hoping integrating it to HA and enjoying the energy dashboard would be a salvation.

Anyone got it to work with this integration?
