Autostart using systemd
</h1>
</header>
<hr class="divider">
<p>Newer Linux distributions are trending towards using <code class="highlighter-rouge">systemd</code> for managing daemons. Typically, systems based on Fedora, ArchLinux, or Debian (8 or later) use <code class="highlighter-rouge">systemd</code>. This includes Ubuntu releases including and after 15.04, CentOS, and Red Hat. If you are unsure if your system is using <code class="highlighter-rouge">systemd</code>, you may check with the following command:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>ps -p 1 -o <span class="nv">comm</span><span class="o">=</span>
</code></pre>
</div>
<p>If the preceding command returns the string <code class="highlighter-rouge">systemd</code>, continue with the instructions below.</p>
<p>A service file is needed to control Home Assistant with <code class="highlighter-rouge">systemd</code>. The template below should be created using a text editor. Note, root permissions via <code class="highlighter-rouge">sudo</code> will likely be needed. The following should be noted to modify the template:</p>
<ul>
<li><code class="highlighter-rouge">ExecStart</code> contains the path to <code class="highlighter-rouge">hass</code> and this may vary. Check with <code class="highlighter-rouge">whereis hass</code> for the location.</li>
<li>For most systems, the file is <code class="highlighter-rouge">/etc/systemd/system/home-assistant@[your user].service</code> with [your user] replaced by the user account that Home Assistant will run as (normally <code class="highlighter-rouge">homeassistant</code>). In particular, this is the case for Ubuntu 16.04.</li>
<li>If unfamiliar with command-line text editors, <code class="highlighter-rouge">sudo nano -w [filename]</code> can be used with <code class="highlighter-rouge">[filename]</code> replaced with the full path to the file. Ex. <code class="highlighter-rouge">sudo nano -w /etc/systemd/system/home-assistant@[your user].service</code>. After text entered, press CTRL-X then press Y to save and exit.</li>
<li>If youre running Home Assistant in a Python virtual environment or a Docker container, please skip to the appropriate template listed below.</li>
</ul>
<div class="highlighter-rouge"><pre class="highlight"><code>[Unit]
Description=Home Assistant
After=network-online.target
[Service]
Type=simple
User=%i
ExecStart=/usr/bin/hass
[Install]
WantedBy=multi-user.target
</code></pre>
</div>
<h3><a class="title-link" name="python-virtual-environment" href="#python-virtual-environment"></a> Python virtual environment</h3>
<p>If youve setup Home Assistant in <code class="highlighter-rouge">virtualenv</code> following our <a href="https://home-assistant.io/getting-started/installation-virtualenv/">Python installation guide</a> or <a href="https://home-assistant.io/getting-started/installation-raspberry-pi/">manual installation guide for Raspberry Pi</a>, the following template should work for you. If Home Assistant install is not located at <code class="highlighter-rouge">/srv/homeassistant</code>, please modify the <code class="highlighter-rouge">ExecStart=</code> line appropriately.</p>
<div class="highlighter-rouge"><pre class="highlight"><code>[Unit]
Description=Home Assistant
After=network-online.target
[Service]
Type=simple
User=%i
ExecStart=/srv/homeassistant/bin/hass -c "/home/homeassistant/.homeassistant"
[Install]
WantedBy=multi-user.target
</code></pre>
</div>
<h3><a class="title-link" name="docker" href="#docker"></a> Docker</h3>
<p>If you want to use Docker, the following template should work for you.</p>
<div class="highlighter-rouge"><pre class="highlight"><code>[Unit]
Description=Home Assistant
Requires=docker.service
After=docker.service
[Service]
Restart=always
RestartSec=3
ExecStart=/usr/bin/docker run --name="home-assistant-%i" -v /home/%i/.homeassistant/:/config -v /etc/localtime:/etc/localtime:ro --net=host homeassistant/home-assistant
ExecStop=/usr/bin/docker stop -t 2 home-assistant-%i
ExecStopPost=/usr/bin/docker rm -f home-assistant-%i
[Install]
WantedBy=multi-user.target
</code></pre>
</div>
<h3>Next Steps</h3>
<p>You need to reload <code class="highlighter-rouge">systemd</code> to make the daemon aware of the new configuration.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl --system daemon-reload
</code></pre>
</div>
<p>To have Home Assistant start automatically at boot, enable the service.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl <span class="nb">enable </span>home-assistant@[your user]
</code></pre>
</div>
<p>To disable the automatic start, use this command.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl disable home-assistant@[your user]
</code></pre>
</div>
<p>To start Home Assistant now, use this command.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl start home-assistant@[your user]
</code></pre>
</div>
<p>You can also substitute the <code class="highlighter-rouge">start</code> above with <code class="highlighter-rouge">stop</code> to stop Home Assistant, <code class="highlighter-rouge">restart</code> to restart Home Assistant, and status to see a brief status report as seen below.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl status home-assistant@[your user]
● home-assistant@fab.service - Home Assistant <span class="k">for</span> <span class="o">[</span>your user]

└─30426 /usr/bin/python3 /usr/bin/hass
<span class="o">[</span>...]
</code></pre>
</div>
<p>To get Home Assistants logging output, simple use <code class="highlighter-rouge">journalctl</code>.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo journalctl -f -u home-assistant@[your user]
</code></pre>
</div>
<p>Because the log can scroll quite quickly, you can select to view only the error lines:</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo journalctl -f -u home-assistant@[your user] | grep -i <span class="s1">'error'</span>
</code></pre>
</div>
<p>When working on Home Assistant, you can easily restart the system and then watch the log output by combining the above commands using <code class="highlighter-rouge">&amp;&amp;</code></p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>sudo systemctl restart home-assistant@[your user] <span class="o">&amp;&amp;</span> sudo journalctl -f -u home-assistant@[your user]
</code></pre>
