If you already have Python 3.5 or later installed, you can easily give Home Assistant a spin.
It's recommended when installing Python packages that you use a virtual environment. This will make sure that your Python installation and Home Assistant installation won't impact one another.
_(If you're on a Debian based system, you will need to install Python virtual environment support using `apt-get install python3-pip python3-venv`)_
1. Create a virtual environment:
```
python3 -m venv homeassistant
```
2. Open virtual environment:
```
cd homeassistant
```
3. Activate virtual environment:
```
source bin/activate
```
4. Install Home Assistant:
```
python3 -m pip install --upgrade homeassistant
```
5. Run Home Assistant:
```
hass --open-ui
```
### {% linkable_title Notes %}
