This is a community curated list of frequently asked questions (FAQ) about the installation, setup, and usage of Home Assistant.
There will be no support for Python 2.x. Python 2 will be EOL in 2020 and it doesn’t make any sense to support a release which was planned to be retired in 2015.
When a component does not show up, many different things can be the case. Before you try any of these steps, make sure to look at the
home-assistant.log file and see if there are any errors related to your component you are trying to set up.
If you have incorrect entries in your configuration files you can use the
check_config script to assist in identifying them:
hass --script check_config.
Why are you not using tools X for the documentation? Because the current solution works for us and we see no additional value in using a separate publishing platform.
Home Assistant is a FAST moving open source project. This means occasionally the official documentation will not be 100% current or complete. Since this is an open source volunteer project, we would encourage anyone who finds gaps in the documentation to click the
edit this page on Github link in the top right and submit any corrections/enhancements they may find useful.
In the absence of information, many users find it beneficial to look at other people’s configurations to find examples of what they want to accomplish in their own configurations. The easiest way to find these configurations is through this Github search.
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
The problem which leads to
distutils.errors.DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both is a known issue if you’re on a Mac using Homebrew to install Python. Please follow these instructions to resolve it.
On a Debian system, install the Python 3 YAML library by
sudo apt-get install python3-yaml.
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 python3d and pip3 by
sudo apt-get install python3-pip.
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.
chrome -> settings -> site settings -> storage -> search for your URL for Home Assistant-> “clear & reset”
It can happen that you get a traceback that notify you about connection issues while running Home Assistant. Eg.
ConnectionRefusedError: [Errno 111] Connection refused
The chance is very high that this is not a bug but an issue with the service/daemon itself. Check your network (DNS, DHCP, uplink, etc.) first and make sure that Home Assistant and the service are poperly configured. Keep in mind that webservices can be down.
Close the windows or tab and clear the cache. The frontend is aggressively caching and clearing the cache ensures that the frontend is reloaded when you access it the next time.
Almost all components have external dependencies to communicate with your devices and services. Sometimes Home Assistant is unable to install the necessary dependencies. If this is the case, it should show up in
The first step is trying to restart Home Assistant and see if the problem persists. If it does, look at the log to see what the error is. If you can’t figure it out, please report it so we can investigate what is going on.
