0.25: Custom frontend panels, Jupyter notebooks, DirecTV.

When Home Assistant started the focus has always been on making a great developer experience. Allowing anyone to add support for their favorite devices to Home Assistant easily. This focus has been a great success since we now have 339 components and platforms!

Starting with this release, we are extending our extensibility to the frontend. Starting this release, any component can add its own page to the frontend. Examples of this today are the map, logbook and history. We are looking forward to all the crazy panels you’ll come up with!

We have also seen an exciting trend of people starting to visualize their Internet of Things data using Jupyter Notebooks, which are a great way to create and share documents that contain code, visualizations, and explanatory text. In case you missed it, the blog post by @kireyeu shows an advanced usecase while our Notebooks in the Home Assistant Notebooks repository cover the basics.

This release also includes a bunch of new integrations, among others three new media player platforms. This means that today Home Assistant can talk to 26 different media players!

The brand-new iFrame panel component allows you to add other websites as pages in the Home Assistant frontend. They will show up in the sidebar and can be used the same way as you open the frontend in your browser but all within one view.

I would like to do a shoutout to @fabianhjr. He has started adding typing data (PEP484) to the Home Assistant core. This will help us identify issues before they are released.

ESP8266 and MicroPython - Part 1

The first release of Micropython for ESP8266 was delivered a couple of weeks ago. The [documentation](http://docs.micropython.org/en/latest/) covers a lot of ground. This post is providing only a little summary which should get you started.

Until a couple of weeks ago, the pre-built MicroPython binary for the ESP8266 was only available to backers of the Kickstarter campaign. This has changed now and it is available to the public for download.

IoT Data Exploration with Jupyter Notebooks

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.

As we learned in the recent blog post by Fabian, all operational data of your Home Assistant application is stored locally and is available for exploration. Our first steps were querying data with the DB Browser for SQLite, 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?

This post will help you get set up using a few popular data scientist tools to allow you to locally process your data:

  •  Pandas: an open source tool for data analysis for Python
  •  matplotlib: a Python plotting library
  •  Jupyter notebook: application for creation and sharing of documents containing live code, visualizations and explanatory text

One of the graphs created with this tutorial.

TL; DR: Use this Jupyter Notebook to visualize of your data

Visualize your IoT data

The history component is tracking everything that is going on within Home Assistant. This means that you have access to all stored information about your home. Our history is not a full-fledged graphical processing and visualization component as you may know from systems and network monitoring tools. The current limitation is that you only can select a day for a visual output of your information and not a period. Also, there is no possibility to drill down on a specific entity.

This blog post will show you ways to export data for reporting, visualization, or further analysis of automation rules.

0.24: SQLAlchemy, KNX, Join by Joaoapps, and SimpliSafe.

It’s time for Home Assistant 0.24 and it’s full of new integration for your Home. It contains some structural changes to our history which requires action from your end, so please keep reading.

MapQuest discontinued their free and direct tile access by Monday, July 11, 2016. With CARTO we found a very cool and suitable solution. They allow us to use their tile for the map. Thank you, CARTO.

Roy Hooper did an amazing job migrating the history support from being tied to SQLite to use the ORM SQLAlchemy instead. This means that you can now use any SQL backend for the history. So besides SQLite you can now databases like MySQL or PostgreSQL. However, this does require that you install SQLAlchemy and run a command to migrate your existing history over. We tried to make the process as seamless as possible by introducing a new command line script:

pip3 install SQLAlchemy
hass --script db_migrator --config /path/to/config

You can omit the --config option if you use the default configuration directory. Run the script with --help to get more options.

Hotfix 0.24.1 - July 21

Quick hot fix after we found a bug in the migrator where it wouldn’t work with a database in a non-standard location. Thanks to @n8henrie and @AlucardZero.

Backward-incompatible changes

  • Migrating existing databases (see above).
  • The APCUPSd Sensor was updated. This will need that you modify your configuration.yaml file.
  • Entity IDs of Verisure locks will change. This is a one time change but should improve readability.

PocketCHIP running Home Assistant

Over a year ago I participated in the [kickstarter campaign](https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer/description) for "CHIP - The World's First Nine Dollar Computer" by [Next Thing Co.](https://www.nextthing.co/). 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...

0.23: Envisalink, Homematic, HDMI-CEC and Sony Bravia TV

It’s time for Home Assistant 0.23 and it’s full of goodies. It’s also the release that bumps us over a 1000 tests and to 94% test coverage! Also our install issues on the Raspberry Pi and Synology have been resolved.

This release brings support for two new ecosystems: Envisalink and Homematic. We can now also control your TV via HDMI using HDMI-CEC (which works on the Pi!) and another cool feature is the persistent notifications which allow you to add a notification to the frontend till dismissed.

Wink support has been dramatically improved by migrating to the PubNub API. This allows Wink to push changes from their system to Home Assistant. This change came just in time as somehow our Wink integration was causing a lot of requests to their servers. Thanks to Wink for letting us know so we could solve it instead of blocking us.

On the config side, you can now store your passwords in your OS keyring or just in a standalone file. We also got a new service to reload the core config so no reboots needed anymore after changing customize settings!

Backward-incompatible changes

  • Homematic thermostat configuration has changed and now depends on the new Homematic component.

Hotfix 0.23.1 - July 2

  • Bump PyVera to 0.2.13 to fix traceback and pyvera thread dying related to bug (@rhooper)
  • HTTP - SSL: Check for OP_NO_COMPRESSION support before trying to use it (@AlucardZero)
  • Wink: Downgraded pubnub to work around pycryptodome conflicts (@w1ll1am23)


  • elevation: was introduced to the configuration for weather/sunrise data. For existing configurations add the value shown in the warning [homeassistant.config] Incomplete core config. Auto detected elevation: 665 to your configuration.yaml file.

Using USB webcams with Home Assistant

In the past month I was thinking about ways to integrate USB webcams into Home Assistant again. The main reason was that this would give those devices a second life and enable one to benefit from low-cost video surveillance. There are a couple of options available like [pygame](http://www.pygame.org/hifi.html) or [SimpleCV](http://www.simplecv.org/) but I never finished something. With the [Local File camera platform](/integrations/local_file) by [Landrash](https://github.com/Landrash) and [motion](http://lavrsen.dk/foswiki/bin/view/Motion/WebHome) you could integrate a local USB webcam with a few very easy steps.

In this blog post I am using a Fedora 24 (will most likely work on other distributions too) installation with Home Assistant 0.22.1 on a Foxconn nT-330i with an old Logitech QuickCam Orbit AF and a Logitech HD Webcam C270. As a start only the Quickcam is used. No multi-camera setup for now.

0.22: Pandora, BT Home Hub 5 and local file camera.

It’s time for the 0.22 release. This was a pretty rough release cycle and we had to issue two hot fixes for our core improvements. But it seems now that all is good and a lot of people have reported that their installs are faster than ever and the occasional quirks no longer occur.

We are aware that our new web stack has caused issues installing Home Assistant on ARM-based platforms. This sadly includes the Raspberry Pi and Synology NAS systems. We’re working on getting to a better solution. For Raspberry Pi, the All-in-One installer will take care of everything for you. We’re working on updating our standalone Raspberry Pi installation guide.

There are two cool things that I want to highlight in this release. The first is Pandora support. This is based on the CLI player called pianobar. This means that your machine running Home Assistant can be connected to the speakers and provide your house with tunes.

Another cool addition is the local file camera. This seems very basic at first but will allow you to generate a graph with your favorite 3rd party graphing tool and display it on your Home Assistant dashboard. We’re looking forward to see what you can do with this!

Breaking change

  • The new Netatmo support caused us to change how Netatmo are configured. It’s now done via its own component.

Home Assistant at PyCon 2016

It’s been already almost two weeks ago that a few of the Home Assistant developers headed towards Portland for PyCon 2016 - the conference about everything Python. We were there to learn all the nifty tricks to make our code better but most of all, to talk Home Automation.

Home Assistant developers Couple of Home Assistant devs. Left to right: [Paulus (@balloob)], [Alex (@infamy)], [Ryan (@rmkraus)].

On Monday I (Paulus) gave a presentation about Home Assistant to an audience of over 400 people! It was a bit scary at first but after a couple of minutes it went all great including some great questions afterwards. Slides can be found here and the talk is embedded right below:

One of the things that really impressed me was the amount of people that approached us to tell how they love Home Assistant, how it has replaced their previous solution, how they enjoyed contributing to Home Assistant and how helpful our community is. It makes me proud of Home Assistant and especially our community.
