+    <p><em>This is the first blog post by Anton Kireyeu. A new contributor to Home Assistant who will focus on exploring and visualizing Home Assistant data.</em></p>
+<p>As we learned in the recent <a href="https://home-assistant.io/blog/2016/07/19/visualizing-your-iot-data/">blog post by Fabian</a>, all operational data of your Home Assistant application is stored locally and is available for exploration. Our first steps were querying data with the <a href="http://sqlitebrowser.org/">DB Browser for SQLite</a>, exporting the data extract as a CSV file and graphing in LibreOffice. But what else can be done with this data and what tools are there available?</p>
+<p>This post will help you get set up using a few popular data scientist tools to allow you to locally process your data:</p>
+<ul>
+  <li> <a href="http://pandas.pydata.org/">Pandas</a>: an open source tool for data analysis for Python</li>
+  <li> <a href="http://matplotlib.org/">matplotlib</a>: a Python plotting library</li>
+  <li> <a href="https://jupyter.org/">Jupyter notebook</a>: application for creation and sharing of documents containing live code, visualizations and explanatory text</li>
+</ul>

+<p><em>TL; DR: Use <a href="http://nbviewer.jupyter.org/github/home-assistant/home-assistant-notebooks/blob/master/DataExploration-1/DataExploration-1.ipynb">this Jupyter Notebook</a> to visualize of your data</em></p>

-<p>In <a href="/blog/2016/04/30/ibeacons-part-1-making-presence-detection-work-better">Part 1</a> I talked about using iBeacons to improve presence tracking. In part 2 I’ll talk about how to track things like keys that can’t track themselves by using iBeacons.</p>
-<h3><a class="title-link" name="tracking-things-using-ibeacons" href="#tracking-things-using-ibeacons"></a> Tracking things using iBeacons</h3>
-<p>In the first part I mentioned that iBeacons just send out <em>I’m here</em> packets, and we used this to trigger an update when your phone came close to a fixed beacon.</p>
-<p>But beacons don’t have to be fixed.</p>
-<p>Your phone knows roughly where it is located (based on mobile phone masts, Wi-Fi networks or GPS). If your phone sees an <em>I’m here</em> message then it knows the beacon is close.</p>
-<p>If your phone can remember (or tell a server) where it was when it last saw the iBeacon - then it knows where the beacon was. So the result of this is that you can track where an iBeacon was - even though the iBeacon doesn’t have any tracking technology itself.</p>
-<p>So if you put an iBeacon on your keys or in your car - then you can track them.</p>

-  Here are my keys - with a Estimote Nearable iBeacon stuck to them. Ugly but effective!
