<h3>Directions for installing on Raspberry Pi All-In-One installer and HASSbian:</h3>
|
||||
<p>Here are the steps to make the <em>SenseHAT</em> sensor work <em>successfully</em> with the virtual enviroment versions.</p>
|
||||
|
||||
<h4>Install SenseHAT package to <em>homeassistant_venv</em></h4>
|
||||
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="c"># switch to the homeassistant_venv environment</span>
|
||||
sudo su -s /bin/bash homeassistant
|
||||
<span class="nb">source</span> /srv/homeassistant/homeassistant_venv/bin/activate
|
||||
|
||||
<span class="c"># install the sense-hat lib</span>
|
||||
pip3 install sense-hat
|
||||
<span class="c"># be patient, this will take a long while</span>
|
||||
</code></pre>
|
||||
</div>
|
||||
<h4>Return to <code class="highlighter-rouge">pi</code></h4>
|
||||
<p>Type <code class="highlighter-rouge">exit</code> to quit out of the <em>homeassistant_venv</em> back to your <code class="highlighter-rouge">pi</code> environment.</p>
|
||||
|
||||
<p>As all of the following steps should be under the <code class="highlighter-rouge">pi</code> user environment.</p>
|
||||
|
||||
<h6>Install <em>RTIMU</em></h6>
|
||||
|
||||
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="c"># Install RTIMU to pi user environment</span>
|
||||
pip3 install rtimulib
|
||||
|
||||
<span class="c"># Add symlink to RTIMU in _homeassistant_venv_</span>
|
||||
<span class="c"># Create a symlink using the following command:</span>
|
||||
ln -s /usr/lib/python3/dist-packages/RTIMU.cpython-34m-arm-linux-gnueabihf.so /srv/homeassistant/homeassistant_venv/lib/python3.4/
|
||||
|
||||
<span class="c"># Add _homeassistant_ user to the _input_ and the _i2c_ groups</span>
|
||||
sudo addgroup homeassistant input
|
||||
sudo addgroup homeassistant i2c
|
||||
|
||||
<span class="c"># Reboot Raspberry Pi to apply changes</span>
|
||||
sudo reboot
|
||||
</code></pre>
|
||||
</div>
|
||||
|
||||
<p>Unfortunately enabling the SenseHAT Sensor component for a Virtual Environment install of Home-Assistant fails with errors.
|
||||
<em>(The Raspberry Pi All-In-One installer and HASSbian both run Home-Assistant in an virtual environment).</em>
|
||||
These issues have been discussed in the repository issue (#5093)[https://github.com/home-assistant/home-assistant/issues/5093)</p>
|
||||
|
||||
<p>This fix has been tested with a clean install of:</p>

||||
|
||||
<ul>

||||
<li><a href="https://downloads.raspberrypi.org/raspbian/images/raspbian-2017-01-10/">Raspbian Jessie - version January 2017</a></li>
|
||||
</ul>
|
||||
|
||||
<p>and</p>
