For "integrated" stuff, their stance is "UI Must Work". Tracing down the requirements, here: https://design.home-assistant.io/#concepts/home https://developers.home-assistant.io/docs/configuration_yaml_index https://github.com/home-assistant/architecture/blob/master/adr/0010-integration-co… ...usually there's YAML kicking around the backend, but for normal usage, normal users, the goal is to be able to configure all (most) things via UI. I've had to drop to YAML to configure (eg) writing stats to indexdb/graphana vs. sqlite (or something), or maybe to drop in or update an API_KEY or non-standard host/port, but 99% of the time the config is baroque, but usable via the web-app.

I also use HomeAssistant, and am quite happy with it, but i wish, they would start including the [`remote_homeassistant`](https://github.com/custom-components/remote_homeassistant) addon. It solves the Usecase, where not all BT(LE) devices in the house are reachable from the main HA, and you need remote "pickups" for their signals, and then want to integrate them back into the "master instance". It also solves a bunch of other problems, like integrating some sensors of the HA of your holiday home into the HA of your main home. The author describes the rationale better here: https://github.com/home-assistant/architecture/issues/246 For some reason, NabuCasa doesn't want to integrate it. Maybe they see it as competing with an own upcoming (cloud?) solution of their own?

It’s all clearly defined in ADR-007 https://github.com/home-assistant/architecture/blob/master/a... The TL;DR: Authentication for devices and services are via the UI only (to deal with OAuth2, refresh tokens, auto-updating IPs via mDNS). Automations/scripts/scenes are both YAML or UI.

One word of caution, the world of Z-Wave with Home Assistant is about to be flipped on its head due to some developer personal constraints. https://github.com/home-assistant/architecture/issues/483

A community that I've seen doing this pretty well is the Home Assistant community. You might wanna check their examples out. https://github.com/home-assistant/architecture
