- Do I need to install anything or write code to use Home Assistant?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does Home Assistant work on a phone?
- No. It needs a computer.
- Can I use Home Assistant commercially?
- The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
