I don't really get HA. It seems oversized for what most people need for their own home automation. Maybe I'm just jaded because my house is fully KNX wired, but the only "addon" I need is NodeRed for some Dashboard and Integrations of ESPs that are just for additional monitoring. It runs in a lonely docker container just fine and does not need a million dependencies.
Then again, I also don't understand why people buy every "smart"/cloud based device and try to glue everything together - when the hardware fails most likely the vendor does not exist or no longer supports it anymore and then you start all over again.
Your house is wired with an alternative and you can't imagine people who DON'T have that infrastructure are looking for a way of doing smart automations?
I have been using HA for years and I love it, it does what I need it to do while operating quietly in the background. I don't have any devices that are "cloud based" so I don't care if the vendor goes out of business or not.
My stuff is a mix of wifi, z-wave, and my cameras are ethernet cabled but can be integrated with onvif.
My house was also built in 1958, there's no chance I'm running KNX cabling anywhere, much less all the places I have devices.
