Home Assistant and the Home Assistant Operating System have a log of bugs, regressions, shortcomings and usability problems. They have far too many problems for me to even track them or write all of them down. That's not related to your experience. There are other issues which stand out based on what you've written.
The so called issues you've encountered appear to be due to insufficient knowledge and experience. It might be a good idea to learn more to better understand what's going on. What you've done is similar to complaining about being last in a swimming competition without learning how to swim properly first and without proper practice for several years.
im perfectly fine with that, and am not asking for a refund or anything. i am merely pointing out that as a fellow startup person in tech this kind of friction log is typically what you want to improve the experience, so that in 3-5 years you are not blaming your user for their skill issue when really its always possible to improve the experience. this is what i did for a living. this comes from empathy.
