I'm not sure if you realize it, but you're demonstrating exactly the thing described in the blog post.
Why the hell do I need a backup for my light switch?
The first time I installed HomeAssistant (on a Raspberry Pi), it worked great for a couple of months, then it bricked itself because it ran out of log space. I re-installed it. A couple of months later, it auto-updated itself and decided to lock me out because apparently it now required that you log in where it previously didn't. At around the same time, Apple locked out their HomeKit HA integration so I could no longer tell Siri to flip the lights. At that point I just gave up.
Recently I tried reinstalling it again, and let's just say I don't recommend it if you value your sanity.
Every time I look into HA, I face this kind of cognitive dissonance between my experience and people condescendingly telling me that I'm obviously doing something wrong.
I just want a zwave hub for my light switches. I don't want any of this crap.
