<p>Today we’re happy to announce our brand new Raspberry Pi image! It is based on Raspbian Lite combined with HASS so we decided to call it Hassbian.</p>
<p>This image comes pre-installed with everything you need to get started with Home Assistant right away.</p>
<p>To get started, check out the installation instructions in <a href="/getting-started/installation-raspberry-pi-image/">the getting started section</a> or watch the latest video by <a href="https://www.youtube.com/channel/UCLecVrux63S6aYiErxdiy4w">BRUHAutomation</a>:</p>
<div class="videoWrapper">
<iframe width="560" height="315" src="https://www.youtube.com/embed/iIz6XqDwHEk" frameborder="0" allowfullscreen=""></iframe>
</div>
<h3><a class="title-link" name="under-the-hood" href="#under-the-hood"></a> Under the hood</h3>
<p>It’s based on Raspbian Lite and generated with a fork of the same <a href="https://github.com/home-assistant/pi-gen">script</a> that builds the <a href="https://raspberrypi.org/downloads/raspbian/">official Raspbian images</a>. For installation of HASS it follows the same install instructions as the <a href="/getting-started/installation-raspberry-pi/">Manual installation</a>. Please note that this project has no association with the Raspberry Pi foundation or their projects.</p>
<p>On first boot the latest release of Home Assistant will be installed and can be reached after 3~5 minutes. Pre-installed on this image is the MQTT broker <a href="https://mosquitto.org/">Mosquitto</a>, Bluetooth support and settings for the <code class="highlighter-rouge">homeassistant</code> account to use the GPIO pins of the Raspberry Pi. Mosquitto is not activated by default.</p>
<p>As it is today there is no pre-compiled Z-Wave support but it can be installed by following the <a href="/getting-started/z-wave/">Getting started instructions for Z-Wave</a>.</p>
<p>Happy Automating!</p>

<div class="entry-content clearfix">
<p>Two weeks ago, September 17 marked our 3 year anniversary. In this time Home Assistant managed to grow from a simple script that turned on my lights when the sun set to a kick ass open source project with the best community an open-source project could wish for. This release contains features, bug fixes and performance tweaks by a total of <strong>50</strong> different people! We have also managed to cross the 1000 forks on GitHub. Talking about momentum!</p>
<p>This is a big release as we’ve completely overhauled the internals of Home Assistant. When I initially wrote Home Assistant, still figuring out the ins and outs of Python, I went for an approach that I was familiar with for an application with many moving parts: threads and locks. This approach has served us well over the years but it was slower than it needed to be, especially on limited hardware.</p>
<p>This all changed when <a href="https://github.com/bbangert">@bbangert</a> came around and took on the tough job to migrate the core over to use asynchronous programming. He did an amazing job and I am happy to say that the initial port has been done and is included in this release! On top of that, we have been able to keep our simple and straightforward API at the same time. We are still in the process of migrating more and more components over to the asynchronous API, so expect more speedups and awesome features in the upcoming releases.</p>
<h3><a class="title-link" name="sleepiq-and-openalpr" href="#sleepiq-and-openalpr"></a> SleepIQ and OpenALPR</h3>
<p>There now is support for two new super cool things: Beds and license plates. <a href="https://github.com/technicalpickles">@technicalpickles</a> created a <a href="/components/sleepiq/">SleepIQ</a> component that let you monitor the sensor data of your bed. <a href="https://github.com/pvizeli">@pvizeli</a> has added license plate recognition based on <a href="/components/openalpr/">OpenALPR</a>! This means that you can now be notified about which car is parked on your driveway or in your garage. I also would like to use this opportunity to give a big shoutout to <a href="https://github.com/pvizeli">@pvizeli</a> for being such an awesome member of our community. He joined us at the end of June and has helped crush bugs and add awesome features ever since (65 pull requests already!).</p>
<h3><a class="title-link" name="configuration-validation" href="#configuration-validation"></a> Configuration validation</h3>
<p>On the voluptuous front we have also made great progress. We were able to fully remove the legacy config helpers and have migrated 323 of the 346 components and platforms that needed migrating! This does mean that for some components the configuration has slightly changed, make sure to check out the breaking changes section at the bottom for more info. Thanks everybody for reviewing the Pull requests, testing the changes, and reporting issues.</p>
<h3><a class="title-link" name="delayed-release" href="#delayed-release"></a> Delayed Release</h3>
<p>As you might have noticed, this release has been delayed by 5 days. This was due to a rare, difficult to reproduce problem with the Python interpreter. A huuuuge thanks to all the people that have helped countless hours in researching, debugging and fixing this issue: <a href="https://github.com/bbangert">@bbangert</a>, <a href="https://github.com/turbokongen">@turbokongen</a>, <a href="https://github.com/lwis">@lwis</a>, <a href="https://github.com/kellerza">@kellerza</a>, <a href="https://github.com/technicalpickles">@technicalpickles</a>, <a href="https://github.com/pvizeli">@pvizeli</a>, <a href="https://github.com/persandstrom">@persandstrom</a> and <a href="https://github.com/joyrider3774">@joyrider3774</a>. I am grateful to have all of you as part of the Home Assistant community.</p>
<h3><a class="title-link" name="hide-automation-rules" href="#hide-automation-rules"></a> Hide automation rules</h3>
<p>Since 0.28 <a href="/blog/2016/09/10/notify-group-reload-api-pihole/#reload-automation-rules">automation rules</a> can be reloaded directly from the frontend. By default all automation rules are shown.

<p>It’s already time for 0.28 thanks to our super short release cycles. Now, it’ official…we hit 4000 stars on Github. That’s amazing. Sorry, not as amazing as all the stuff that was going on for 0.27 but still pretty awesome.</p>
<h3><a class="title-link" name="reload-automation-rules" href="#reload-automation-rules"></a> Reload automation rules</h3>
<p>This release brings you a huge improvement of the <a href="/components/automation/">automation</a> and <a href="/components/group/">group</a> handling. Both can be reloaded without a Home Assistant restart by calling their new reload services. The automations can be controlled directly from the frontend.</p>

<h3><a class="title-link" name="raspberry-pi-installation-guide" href="#raspberry-pi-installation-guide"></a> Raspberry Pi installation guide</h3>
<p>Singleboard computers are very popular to run Home Assistant. To support this fact, the <a href="/getting-started/installation-raspberry-pi/">installation documentation</a> for the Raspberry Pi devices was re-written to get users started as quickly as possible. <a href="https://github.com/Landrash">@Landrash</a> took the lead with on this tasks with help from <a href="https://github.com/kellerza">@kellerza</a> and <a href="https://github.com/MartinHjelmare">@MartinHjelmare</a>.</p>
<h3><a class="title-link" name="climate-and--cover" href="#climate-and--cover"></a> Climate and cover</h3>
<p>There are countless bugfixes included in this release which will make your experience with the <code class="highlighter-rouge">climate</code> and the <code class="highlighter-rouge">cover</code> platforms better. Two week ago was the biggest merger of implementations released that ever happened in the history of Home Assistant. Thanks to <a href="https://github.com/turbokongen">@turbokongen</a>, <a href="https://github.com/pvizeli">@pvizeli</a>, <a href="https://github.com/djbanks">@djbanks</a>, <a href="https://github.com/danielperna84">@danielperna84</a>, and others the improvements on the code and the frontend side is continuing…</p>
<h3><a class="title-link" name="api-documentation" href="#api-documentation"></a> API documentation</h3>
<p>The <a href="https://dev-docs.home-assistant.io/en/dev/">Home Assistant API Documentation</a> is a great addition to the already exisiting user documentation. The focus is not end-users but developers who whant to get details about the code without actually browsing the code on Github.</p>
<h3><a class="title-link" name="configuration-validation" href="#configuration-validation"></a> Configuration validation</h3>
<p>The validation of the configuration is still on-going. Approximatly 80 % is done. This means that we will propably talk about this topic in the next release notes again. To align the configuration of components and platforms we needed to break some. Please refer to the Breaking changes section to check if you need to update your configuration or simple check your log for configuration validation errors. Thanks to <a href="https://github.com/kellerza">@kellerza</a>, <a href="https://github.com/fabaff">@fabaff</a>, <a href="https://github.com/Teagan42">@Teagan42</a>, and <a href="https://github.com/pvizeli">@pvizeli</a> for your effort!</p>

So, part 1 of <a href="/blog/2016/07/28/esp8266-and-micropython-part1/">ESP8266 and MicroPython</a> was pretty lame, right? Instead of getting information out of Home Assistant we are going a step forward and create our own sensor which is sending details about its state to a Home Assistant instance.</p>

<p>This week’s blog post could only be possibly described by exactly one hashtag:</p>
<h1>#Amazing</h1>
<p><sup>or <sup>maybe<sup>#supersized</sup></sup></sup></p>
<p>Keep reading to see what <strong>#Amazing</strong> things we have in store for you this week 😄! And make sure you read all the way to the end, because I left a present down there for those committed few among you :)</p>
<p>But first…</p>
<h2><a class="title-link" name="some-general-housekeeping" href="#some-general-housekeeping"></a> Some general housekeeping</h2>
<p>Paulus (<a href="https://github.com/balloob">@balloob</a>) is on vacation in Europe this week, so you will all have to deal with me, Robbie (<a href="https://github.com/robbiet480">@robbiet480</a>) for this release blog post. Don’t worry, Paulus will be back to tearing apart your pull requests in no time 😈.</p>
<p>Special thanks to my awesome helpers for this week’s release who are looking over my shoulder to make sure I’m crossing my t’s and dotting my i’s: <a href="https://github.com/Teagan42">@Teagan42</a>, <a href="https://github.com/infamy">@infamy</a> and <a href="https://github.com/fabaff">@fabaff</a>.</p>
<p>For my next trick, let’s hand out some…</p>
<h2><a class="title-link" name="trophies" href="#trophies"></a> Trophies</h2>
<p>I felt that I had to 1-up Paulus (<a href="https://github.com/balloob">@balloob</a>) somehow with his 500,000 pageviews stat he shared in the <a href="/blog/2016/08/13/foursquare-fast-com-ffmpeg-gpsd/">0.26 blog post</a>, so I pushed myself and our development community as a whole super hard the last two weeks to put a lot of love into Home Assistant to bring you not just one, but six <strong>#Amazing</strong> stats for this release. As of 0.27, we have now surpassed the following milestones:</p>
<ul>
<li><a href="https://travis-ci.org/home-assistant/home-assistant/builds/154660811">10,000</a> builds on Travis (congrats to <a href="https://github.com/BluGeni">@BluGeni</a>)</li>
<li><a href="https://github.com/home-assistant/home-assistant/pull/3000">3,000</a> issues and pull requests (thanks <a href="https://github.com/kellerza">@kellerza</a>!)</li>
<li><a href="https://github.com/home-assistant/home-assistant/pull/2991">2,000</a> pull requests alone (awesome <a href="https://github.com/fabaff">@fabaff</a>!!)</li>
<li>900 forks on Github!</li>
</ul>
<p>In addition,</p>
<ul>
<li>We are very close to 4,000 stars on Github!</li>
<li><a href="https://github.com/home-assistant/home-assistant/graphs/contributors">I’m now #5 contributor by most commits!!!</a> Hey wait, how’d this get in here 😳…</li>
</ul>
<p>Now that we have that great news out of the way, onto this week’s release which is going to keep the <strong>#Amazing</strong> gravy train rolling right along and get to the stuff you all <em>really</em> are here for.</p>
<h2><a class="title-link" name="027" href="#027"></a> 0.27</h2>
<p>While this release is <strong>#Amazing</strong>, we had to break a few eggs (now you understand the title reference!) to make a beautiful omelette (using home automation obviously) so some platforms and components have needed to introduce breaking changes. Please make sure to read the <a href="#breaking-changes">Breaking Changes</a> section below.</p>
<h3><a class="title-link" name="hue-bridge-emulation" href="#hue-bridge-emulation"></a> Hue Bridge Emulation</h3>
<p>Thanks to <a href="https://github.com/mgbowen">@mgbowen</a> we now have the functionality previously provided by <a href="https://github.com/blocke">@blocke</a>’s <a href="https://github.com/blocke/ha-local-echo">ha-local-echo</a> <a href="/components/emulated_hue/">built right into Home Assistant</a>! This means that for those of you with devices that either lack or have a subpar integration with Home Assistant (looking at you Amazon Echo) you can now have a better experience by having your Home Assistant pretend to be a Hue Bridge. Personally, I have used <a href="https://github.com/auchter">@auchter</a>’s <a href="https://github.com/auchter/haaska">Haaska</a> previously but found that it was slow to respond and sometimes failed entirely. With the new <a href="/components/emulated_hue/"><code class="highlighter-rouge">emulated_hue</code></a> component, you can have local control of entities through Amazon Echo.</p>
<h3><a class="title-link" name="notification-improvements" href="#notification-improvements"></a> Notification improvements</h3>
<p>We have some excellent upgrades to the notification system coming to you in 0.27, courtesy of me, <a href="https://github.com/robbiet480">@robbiet480</a>.</p>
<h4><a class="title-link" name="html5-push-notifications" href="#html5-push-notifications"></a> HTML5 Push Notifications</h4>
<p>This release adds support for <a href="/components/notify.html5/">HTML5</a> push notifications on Chrome/Firefox/Opera on both desktop and Android devices. This means that you can send a notification to your phone even when your Home Assistant is not open in your mobile browser. When using Chrome you can even include 2 action buttons so that you can control your Home Assistant from your phone’s lock screen, allowing you to do things like sound alarms or unlock your front door, all without leaving the notification. Thanks again to me (<a href="https://github.com/robbiet480">@robbiet480</a>) and Paulus (<a href="https://github.com/balloob">@balloob</a>) for all the hard work on this!</p>
<p class="img">
<img src="/images/screenshots/html5-notify.png" />
</p>
<h4><a class="title-link" name="notification-groups" href="#notification-groups"></a> Notification Groups</h4>
<p>Using the new notify <code class="highlighter-rouge">group</code> platform allows you to cut down a lot of duplicate automation logic by combining multiple notification platforms and <code class="highlighter-rouge">target</code>s into a single notify service. Check out the <a href="/components/notify.group/">docs</a> for more info.</p>
<h4><a class="title-link" name="target-is-no-longer-needed" href="#target-is-no-longer-needed"></a> <code class="highlighter-rouge">target</code> is no longer needed!</h4>
<p>For platforms that support it, starting with the new HTML5 platform, any <code class="highlighter-rouge">target</code>s that are available will be exposed as individual services, so no more having to remember which <code class="highlighter-rouge">target</code>s to use. Please note that the existing services also still exist so you can keep using <code class="highlighter-rouge">target</code> if you wish.</p>
<h3><a class="title-link" name="validate-configuration-before-restarting-home-assistant" href="#validate-configuration-before-restarting-home-assistant"></a> Validate configuration before restarting Home Assistant</h3>
<p>Ever restarted Home Assistant to test a configuration change just to find out there is a validation error? Well, not anymore! <a href="https://github.com/kellerza">@kellerza</a> has added a command line script that will validate your configuration as if you started Home Assistant.</p>
<div class="language-bash highlighter-rouge"><pre class="highlight"><code><span class="gp">$ </span>hass --script check_config
</code></pre>
</div>
<h3><a class="title-link" name="configuration-validation" href="#configuration-validation"></a> Configuration validation</h3>
<p>This release includes a big push on making sure all platforms contain proper configuration validation. This should help in getting your configuration right. Thanks to <a href="https://github.com/fabaff">@fabaff</a>, <a href="https://github.com/pavoni">@pavoni</a>, <a href="https://github.com/pvizeli">@pvizeli</a>, <a href="https://github.com/nkgilley">@nkgilley</a> for all the hard work on this, you all rock!</p>
<p class="img">
<img src="/images/screenshots/config-validation.png" />
</p>
<h3><a class="title-link" name="ffmpeg-motionnoise-sensing" href="#ffmpeg-motionnoise-sensing"></a> FFMpeg motion/noise sensing</h3>
<p>It’s now possible to use <a href="/components/binary_sensor.ffmpeg/">FFMpeg</a> to monitor a video stream and detect motion thanks to a new binary sensor platform by <a href="https://github.com/pvizeli">@pvizeli</a>.</p>
<h3><a class="title-link" name="component-clean-up---thermostat--hvac---climate-rollershutter--garage-door---cover" href="#component-clean-up---thermostat--hvac---climate-rollershutter--garage-door---cover"></a> Component clean up - Thermostat &amp; HVAC -&gt; Climate. Rollershutter &amp; Garage Door -&gt; Cover.</h3>
<p>Due to our wild growth we ended up with a few components that had a lot of overlapping functionality. <a href="https://github.com/turbokongen">@turbokongen</a> took on the hard job on merging them. Thermostat and HVAC platforms are now combined under the new Climate component. Rollershutter and Garage Door platforms are now combined under the new Cover component. You can easily upgrade by just swapping out the name. For example replace <code class="highlighter-rouge">thermostat</code> with <code class="highlighter-rouge">climate</code>. The old components have been deprecated and will be removed in the near future.</p>
<h3><a class="title-link" name="a-new-fan-component" href="#a-new-fan-component"></a> A new <code class="highlighter-rouge">fan</code> component</h3>
<p>Along with the new <code class="highlighter-rouge">climate</code> component, <a href="https://github.com/Teagan42">@Teagan42</a> and I (<a href="https://github.com/robbiet480">@robbiet480</a>) decided we needed something simpler to just control a fan. Currently it has support for controlling Insteon fans. MQTT support will appear in 0.28.0. I tried to get it implemented before 0.27.0 but spent too long writing this blog post 😢.</p>

<p>Thanks all for sticking with me to the end.

<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>I have been working on a new subsystem to complement Home Assistant’s Automation and Scripting components. <code class="highlighter-rouge">AppDaemon</code> is a python daemon that consumes events from Home Assistant and feeds them to snippets of python code called “Apps”. An App is a Python class that is instantiated possibly multiple times from <code class="highlighter-rouge">AppDaemon</code> and registers callbacks for various system events. It is also able to inspect and set state and call services. The API provides a rich environment suited to home automation tasks that can also leverage all the power of Python.</p>

<p>It’s time for 0.26 and it’s again full of new features and fixes. First I want to highlight that we are now having 500 000 monthly pageviews on the website. A big milestone for us! It’s been an amazing journey. Big thanks to the Home Assistant community for being such a delightful bunch.</p>
<p>This release includes code contributed by 31 different people. The biggest change in this release is a new unit system. Instead of picking Celsius or Fahrenheit you’ll have to pick imperial or metric now. This influences the units for your temperature, distance, and weight. This will simplify any platform or component that needs to know this information. Big thanks to <a href="https://github.com/Teagan42">@Teagan42</a> for her hard work on this!</p>

<p><em>This blog post will go into detail about the recent performance optimizations that went into the Home Assistant front end. For people not familiar with the app, check out <a href="https://home-assistant.io/demo">the demo</a> and <a href="https://github.com/home-assistant/home-assistant-polymer">the source</a>.</em></p>
<p>TL; DR: Don’t hack the framework, separate responsibilities, ship less, use service workers, use (future) web standards.</p>
<p>This year at Google I/O I saw Monica from the Polymer team talk about web components and performance. In her talk <a href="https://www.youtube.com/watch?v=zfQoleQEa4w&amp;feature=youtu.be&amp;t=1380">she mentions a mantra</a> that they use in the Polymer team to make things fast: <strong>Do less and be lazy</strong>.</p>
<p>Do less and be lazy. It sounds so obvious and it took a while before it started to dawn on me. I think most of the code I write is pretty fast, but I don’t often stop to take a harder look at how and when it runs in practice. When do we need the result, can it be postponed?</p>
<p>And thus started my journey to take a critical look at how the Home Assistant app was working and how to make things faster. Below is the list of the different things that I did to make it fast.</p>
<p>I hope this list can be useful to other people, as a guide for optimizing their own apps or for avoiding pitfalls when building a new one.</p>
<p>The first thing to do is to measure. The Home Assistant front end is a mobile web app, so we shouldn’t measure this on a machine with 8 cores and gigabytes of ram but instead measure on devices you expect a mobile web app to run: phones. Below are two timelines recorded with Home Assistant 0.18.2 (pre-optimizations) and Google Chrome 53. <strong>On my Mac the app starts in 1400 miliseconds and on my Nexus 5x in ~6500 miliseconds (~4.5 times slower!).</strong></p>

</p>
<p>Although the app takes 6500 milliseconds to load on my phone, it would perform well afterwards. Still, that initial load is unacceptable. You expect to open an app on your phone and be able to use it, quickly. After I applied all the changes described below, I managed to reduce startup time to 900 miliseconds (-35%) on my Mac and 2400 miliseconds (-63%) on my Nexus 5x. <a href="https://home-assistant.io/demo">Check out the demo here.</a></p>
