Thanks @mgejke
Seems I f#%#%ed up my HA install by upgrading to 0.57.2 so I need to find a way to fix that first. Been fighting all night with it without moving forward at all. As soon as I find the solution I will pop right back to this topic.
If you have any ideas or time to have a look my issue is here:

Not sure, but does the upgrade maybe change my config files somehow? Sorry for the off-topic. Will go sleep a bit and hope someone found some kind of way forward!
Thanks for all your great work
