Once connected, you will be prompted to create a user account. This will serve as the administrative account for your Smart Home Hub so be sure to remember the information that you use for the login. There is no password recovery system in place.
Once finished, click CREATE ACCOUNT.
Now you will be asked to name your home and set it's location.
The Location part helps with things like weather reports, sun position data, and other things that can be added latter.
You can also set your Time Zone, Elevation, and unit of measurements.
Click NEXT when finished.
If you have any smart devices already connected to your network, Home Assistant may detect them and let you set them up. Devices like Philips Hue, Lifx, WeMo, Google Cast, and a few others are quite easy to set up using this user interface. You may choose to set these up now or do so later using the Integrations tool in the Configurations menu.
Click FINISH when done.
Now you are all set up and any smart devices that you added from the previous screen will now be available and ready to control using Home Assistant.
On the left you should see the Menu where you can see a Map view, Logbook, History, Hass.io, Configuration, and some Developer tools.
The Configuration menu is where you can add many supported devices and services using Integrations. You can also add new user accounts including non Admin users that can not access the full menu structure.
The General menu is where you can change location info along with reloading and restarting the core services if needed. Area Registry lets you define rooms for better use with Google Home, Alexa, or Home Kit. Automation allows you to create complex automations using a fairly easy form based GUI. Script is similar to Automation, but there is no event trigger. You use Script mostly to create complex combinations of tasks that you want to call repeatedly with an automation or with a button in the user interface.
