We are making Gladys Assistant ( https://gladysassistant.com/ ), an open-source smart home software.
It's less "techy" than HA (no YAML files, no CLI), and UI first.
We have way less integrations for now, but are working hard on it.
Don't hesitate to try it and make us some feedback.
Hass is the kind of software that has a lot of rough edges, but you use it anyway because there's very little direct competition. And every release feels like so much stuff has been finally polished, but then you deploy the new version and there's still a lot of stuff that feels or looks weird (the part-bad-UI-part-YAML automation). I have been using it for a couple of years now and I still haven't decided whether I like it or not.
But it's still a huge piece of work and deserves a lot of praise.
