<p>Today we announce the release of Home Assistant v0.7.2 which includes brand new support by
<a href="https://github.com/sfam">@sfam</a> to integrate with <a href="https://ifttt.com">IFTTT</a>. IFTTT stands for If This, Then That and is a
webservice that integrates with almost every possible webservice out there. Adding Home
Assistant to this mix means Home Assistant can connect with all via IFTTT.</p>
<p>It is now possible to disable your irregation system if it is going to be cloudy tomorrow or tweet
if your smoke alarm goes off.</p>
<p class='img'>
<img src='/images/blog/2015-09-ifttt/splash.png'>
</p>
<p>Head over to the <a href="/components/ifttt.html">setup instructions</a> to get started with IFTTT. Click the
read more button for some example recipes.</p>

Inspried by a <a href="https://github.com/balloob/home-assistant/issues/310">feature requests</a> I started looking into the available options to do monitoring of remote hosts. The feature request is about displaying system information in a similar way than the <a href="/components/sensor.systemmonitor.html">systemmonitor</a> sensor does it for the local system. After a while I started to think that it would be a nice addition for a small home network where no full-blown system monitoring setup is present.</p>
<a name="read-more"></a>
<p>In each of the following examples, make sure to replace the XXX in the url with your correct
host address and api password.</p>
<p>The basic problem is to get the data from the remote host. Starting with <a href="https://pypi.python.org/pypi/psutil">psutil</a> that is used by the systemmonitor sensor, a possible solution is only a click away and named <a href="https://github.com/nicolargo/glances">Glances</a>. Glances has a nice curses-based interface and a <a href="https://github.com/nicolargo/glances/wiki/The-Glances-RESTFULL-JSON-API">RESTful API</a>.</p>
<h2><a class='title-link' name='turn-off-irregation-system-when-not-needed' href='#turn-off-irregation-system-when-not-needed'></a> Turn off irregation system when not needed</h2>
<p>The <a href="/components/sensor.glances.html">Glances sensor</a> sensor uses that API to get all needed data.</p>
<p>In this post a default Fedora 22 Workstation installation is used on the host that should be monitored. In fact, it doesn&rsquo;t matter if the system is the local one or a remote one as long as Glances is available. With some adjustments it should work on your own systems too. The difference will be the package and the firewall management tools.</p>
<p>First some extra packages are needed beside Glances, especially the <a href="http://bottlepy.org/docs/dev/index.html">bottle</a> webserver. I guess that Glances is available for your distribution as well. Otherwise follow those <a href="https://github.com/nicolargo/glances#installation">instructions</a>.</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
</pre></td><td class='code'><pre><code class=''><span class='line'>sudo dnf -y install glances python-bottle</span></code></pre></td></tr></table></div></figure>
<p>On Fedora the Firewall settings are strict. Let&rsquo;s open port 61208 to allow other hosts to connect to that port. This is not needed if you just want to observe your local machine.</p>

</span><span class='line'>sudo firewall-cmd --reload
</span></code></pre></td></tr></table></div></figure>
<p>Launch <code>glances</code> and keep an eye on the output.</p>
