Hey, thanks Nabu Casa

Whatever you have done with HA Mac app, it NO longer works for me! I now have to login via browser, which works just fine. Thanks for the DOWNGRADE?????

Crazy, powerful, but…

Home Assistant is incredibly powerful. However, the extremely complicated UI is not at all user-friendly. The same information can be accessed in so many different ways, not always with the same results, and it is often not apparent which feels can be clicked for more information and which not. In an ideal world. Would be redesigned so that it is much more intuitive without AI, I would never have learned to use it.
