<content type="html"><![CDATA[<p>Thanks to <a href="https://github.com/kireyeu">Anton Kireyeu</a> we are able to present another awesome <a href="https://jupyter.org/">Jupyter notebook</a>. I guess that you all know the graph which Github is using to visualize your commits per day over a time-line. It’s a so-called <a href="https://en.wikipedia.org/wiki/Heat_map">heatmap</a>. If there are more commits, it’s getting hotter. The latest <a href="http://nbviewer.jupyter.org/github/home-assistant/home-assistant-notebooks/blob/master/DataExploration-2/DataExploration-2.ipynb">notebook</a> is capable to do the same thing for your devices. To be more precise, for the hours your devices are home.</p>

<p>Most of the graphs are pretty ugly. So, further beautification will be needed. If you have created a nice report including some amazing graphs then the Home Assistant community would be grateful for sharing them in our <a href="https://community.home-assistant.io/">forum</a>.</p>

<link href="https://home-assistant.io/blog/2016/07/06/pocketchip-running-home-assistant/"/>
<updated>2016-07-06T05:00:00+00:00</updated>
<id>https://home-assistant.io/blog/2016/07/06/pocketchip-running-home-assistant</id>
<content type="html"><![CDATA[<p><img src="https://home-assistant.io/images/blog/2016-07-pocketchip/pocketchip-logo.png" style="clear: right; border:none; box-shadow: none; float: right; margin-bottom: 12px;" width="200" /><br />
Over a year ago I participated in the <a href="https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer/description">kickstarter campaign</a> for “CHIP - The World’s First Nine Dollar Computer” by <a href="https://www.nextthing.co/">Next Thing Co.</a>. I went for the PocketCHIP because of the idea. Display, built-in storage (thus no need for SD cards), battery-powered, and a keyboard are pretty nice features. Last week a package arrives…</p>
<!--more-->
<p>Thanks to <a href="https://www.nextthing.co/">Next Thing Co.</a> and their CHIP which is actually 9 USD the space requirement for a single board computer has decreased. No Ethernet and HDMI output helped with that. But I guess that the next development cycle will allow us to put those boards in a matchbox including wired networking and a SATA interface.</p>

Size comparison of a Cubieboard, OrangePi One, and CHIP.
</p>
<p>If you start using a PocketCHIP you will definitely look like a Blackberry or a GameBoy user. Typing is done with your thumbs :-)</p>
<p>First a couple of tweaks like setting up <code>sudo</code>, upgrading the existing installation, change passwords, enabling ssh, and removal of the annoying stuff then installation of Home Assistant. There is not much to tell…it’s straight-forward. For the sake of completeness below the notes about what I did.</p>
<p>A Debian installation is available by default. This means that some dependencies for Home Assistant are missing. I haven’t checked if a new build for the PocketCHIP would include them. So, after a <code>$ sudo apt-get update</code> installing those dependencies take a minute or two.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ sudo apt-get install python3-dev python3-pip python3-venv
</pre></div>
</div>
</div>
<p>As usual I run Python applications in a <a href="https://docs.python.org/3/library/venv.html">venv</a>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ pvenv ha
</pre></div>
</div>
</div>
<p>Let’s activate the created environment.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ cd ha
$ source bin/activate
</pre></div>
</div>
</div>
<p>If you haven’t seen the next two commands already then you should visit our <a href="https://home-assistant.io/">frontsite</a>.</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>$ pip3 install homeassistant
$ hass --open-ui
</pre></div>

<p>With <code>surf</code> the browsing experience on the low-resolution display is not that great. Most smartphones, even very cheap ones, have touchscreens with higher resolutions. Nevermind, <a href="https://twitter.com/fabaff/status/748852317047418880"><code>midori</code></a> is not better.</p>

PocketCHIP with Home Assistant frontend
</p>
<p>Well, with PocketCHIP and Home Assistant you could run your home automation on a 49 USD device with a touchscreen, an integrated USP, and a keyboard. With the GPIO available on top of the display you could even connect your PocketCHIP directly to sensors and actuators.</p>
