It can happen that you run into trouble while installing Home Assistant. This page is here to help you solve the most common problems.
This utility should have been installed as part of the Python 3.4 installation. Check if Python 3.4 is installed by running
python3 --version. If it is not installed, download it here.
If you are able to successfully run
python3 --version but not
pip3, install Home Assistant by running the following command instead:
$ python3 -m pip install homeassistant
On a Debian system, you can also install python3 by
sudo apt-get install python3, and pip3 by
sudo apt-get install python3-pip.
Pip should come bundled with the latest Python 3 but is omitted by some distributions. If you are unable to run
python3 -m pip --version you can install
pip by downloading the installer and running it with Python 3:
$ python3 get-pip.py
On a Debian system, install the Python 3 YAML library by
sudo apt-get install python3-yaml.
This is a known issue if you’re on a Mac using Homebrew to install Python. Please follow these instructions to resolve it.
In newer Linux distributions (at least Fedora 22/CentOS 7) the access to a host is very limited. This means that you can’t access the Home Assistant frontend that is running on a host outside of the host machine. Windows and OSX machines may also have issues with this.
To fix this you will need to open your machine’s firewall for TCP traffic over port 8123. The method for doing this will vary depending on your operating system and the firewall you have installed. Below are some suggestions to try. Google is your friend here.
For systems with firewalld (Fedora, CentOS/RHEL, etc.):
$ sudo firewall-cmd --permanent --add-port=8123/tcp $ sudo firewall-cmd --reload
For UFW systems (Ubuntu, Debian, Raspbian, etc.):
$ sudo ufw allow 8123/tcp
iptables systems (was the default for older distributions):
$ iptables -I INPUT -p tcp --dport 8123 -j ACCEPT $ iptables-save > /etc/network/iptables.rules # your rules may be saved elsewhere
After upgrading to a new version, you may notice your browser gets stuck at the “loading data” login screen. Close the window/tab and go into your browser settings and delete all the cookies for your URL. You can then log back in and it should work.
