This week’s blog post could only be possibly described by exactly one hashtag:


or maybe#supersized

Keep reading to see what #Amazing 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 :)

But first…

Some general housekeeping

Paulus (@balloob) is on vacation in Europe this week, so you will all have to deal with me, Robbie (@robbiet480) for this release blog post. Don’t worry, Paulus will be back to tearing apart your pull requests in no time 😈.

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: @Teagan42, @infamy and @fabaff.

For my next trick, let’s hand out some…


I felt that I had to 1-up Paulus (@balloob) somehow with his 500,000 pageviews stat he shared in the 0.26 blog post, 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 #Amazing stats for this release. As of 0.27, we have now surpassed the following milestones:

In addition,

Now that we have that great news out of the way, onto this week’s release which is going to keep the #Amazing gravy train rolling right along and get to the stuff you all really are here for.


While this release is #Amazing, 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 Breaking Changes section below.

Hue Bridge Emulation

Thanks to @mgbowen we now have the functionality previously provided by @blocke’s ha-local-echo built right into Home Assistant! 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 @auchter’s Haaska previously but found that it was slow to respond and sometimes failed entirely. With the new emulated_hue component, you can have local control of entities through Amazon Echo.

Notification improvements

We have some excellent upgrades to the notification system coming to you in 0.27, courtesy of me, @robbiet480.

HTML5 Push Notifications

This release adds support for HTML5 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 (@robbiet480) and Paulus (@balloob) for all the hard work on this!

Notification Groups

Using the new notify group platform allows you to cut down a lot of duplicate automation logic by combining multiple notification platforms and targets into a single notify service. Check out the docs for more info.

target is no longer needed!

For platforms that support it, starting with the new HTML5 platform, any targets that are available will be exposed as individual services, so no more having to remember which targets to use. Please note that the existing services also still exist so you can keep using target if you wish.

Validate configuration before restarting Home Assistant

Ever restarted Home Assistant to test a configuration change just to find out there is a validation error? Well, not anymore! @kellerza has added a command line script that will validate your configuration as if you started Home Assistant.

$ hass --script check_config

Configuration validation

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 @fabaff, @pavoni, @pvizeli, @nkgilley for all the hard work on this, you all rock!

FFMpeg motion/noise sensing

It’s now possible to use FFMpeg to monitor a video stream and detect motion thanks to a new binary sensor platform by @pvizeli.

Component clean up - Thermostat & HVAC -> Climate. Rollershutter & Garage Door -> Cover.

Due to our wild growth we ended up with a few components that had a lot of overlapping functionality. @turbokongen 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 thermostat with climate. The old components have been deprecated and will be removed in the near future.

A new fan component

Along with the new climate component, @Teagan42 and I (@robbiet480) 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 😢.

All changes

Breaking changes

  • Ecobee3 occupancy sensors have moved from sensor platform to binary sensor platform.
  • Forecast.io entity IDs are now like sensor.forecastio_temperature. Previously they were like sensor.weather_temperature. Apologies for this change, but we needed to make Forecast.io more generic now that we have many weather platforms.
  • The Loop Energy sensor configuration format changed slightly, please reformat based on the revised documentation.
  • The configuration for the SABnzbd sensor has slightly changed. The prefix type: is no longer required for monitored variables.
  • The IMAP sensor now uses username instead of user.
  • The NZBGet sensor has had so many changes I can’t list them all. Please refer to the documentation for more info.


  • Using the thermostat and hvac components has been deprecated. Please migrate to the new climate component. (just change the component name, the configurations are compatible)
  • Using the rollershutter and garage_door components have also been deprecated. Please migrate to the new cover component. (just change the component name, the configurations are compatible)

Finishing up

Thanks all for sticking with me to the end. I’ll be taking over a lot of Paulus’s (@balloob) work while he is gone, but as I said, don’t worry because he’ll be back well before 0.28.0 comes out. Hopefully you didn’t find this jovial blog post too jarring from our standard style, I just wrote a lot of this at 2am after being awake for almost 20 hours, so I’m a little loopy hahaha 😴.

Also, thanks as always to our developer contributors, documentation contributors, but most of all our users! This would’ve just been a script that Paulus (@balloob) used to control his lights at home if we didn’t have your enthusiasm.

Feel free to let me know what you thought of this blog post and release on Gitter or my Twitter, or even the Home Assistant Twitter. Did I mention we have a brand new Facebook page that you should absolutely Like? There’s a convenient Facebook Like and Twitter follow button right on the sidebar.

I almost forgot about your 🎁 for reading all the way to here: a 🍪! Hope you enjoy it in good health 😄.

Talk to you soon on Gitter and in your pull request comments!
