It’s time for the August release and there is some serious good stuff this time. The core of Home Assistant has gone some serious clean up and a bump in test coverage thanks to @balloob. If you’re a developer, make sure you read up on the deprecation notices. @fabaff did another great round of documenting all the various components.
MQTT Support The big new addition in this release is the support for the MQTT protocol by @fabaff with some help from @balloob. It will now be possible to integrate any IoT device that talks via MQTT. For the initial release we support connecting Home Assistant to a broker (no TLS yet). Components can now subscribe and publish to MQTT topics and also support for the automation component has been added. For more information, see the MQTT component page.

# Example configuration.yaml entry mqtt: broker: IP_ADDRESS_BROKER # All the other options are optional: port: 1883 keepalive: 60 qos: 0 username: your_username password: your_secret_password
Another month has passed and some great new features have landed in Home Assistant. This month release has been made possible by balloob, ettisan, fabaff, gyran, jamespcole, michaelarnauts, miniconfig and rmkraus.
IP Camera Support James has worked very hard to add support for IP cameras to Home Assistant which is included in this release. The initial release focusses on providing generic IP camera support. This means that any webcam that can exposes a JPEG image via a URL can be integrated.
Home Assistant will route the requests to your camera via the server allowing you to expose IP camera’s inside your network via the Home Assistant app.

# Example configuration.yaml entry camera: platform: generic name: my sample camera username: MY_USERNAME password: MY_PASSWORD still_image_url: http://18.104.22.168/jpg/image.jpg
Wow, almost a month has gone by since the last release and this release is packed. The biggest part of this release is probably one that you won’t notice: the frontend has been upgraded from Polymer 0.5 to the brand new released Polymer 1.0. Polymer has been declared stable by the Google overlords which will allow us to expand functionality that was waiting for this moment to arrive.
A big improvement has been brought this release by wind-rider. He took the time to revive the Chromecast support and started improving the media player integration. This triggered other people to join in resulting in a revamped media player experience and support for the Music Player Daemon.

Almost three busy weeks have past since the last release. We used this time to finally make the overhaul to use UTC as the internal date time format. We added a bunch of test coverage in the process to make sure the transition went smoothly. Pleas see the blog post about the UTC refactor for backwards incompatible changes.
This release includes a significant startup boost for the frontend and a fix for Wemo discovery after their latest firmware upgrade.
I would like to give a big shout out to our newest contributor fabaff for taking the time to improve the documentation.Read on →
I have recently merged code to refactor Home Assistant to use only UTC times internally. A much needed refactor. I’ve added some extra test coverage to time sensitive parts to ensure stability. The code has been live in the dev branch for the last 9 days and will be soon released to the master branch.
From now on all internal communication will be done in UTC: time changed events, datetime attributes of states, etc. To get the current time in UTC you can call
homeassistant.util.dt.utcnow(). This is a timezone aware UTC datetime object.
homeassistant.util.dt is a new util package with date helpers.
There is also such a thing as local time. Local time is based on the time zone that you have setup in your
configuration.yaml. Local times should only be used for user facing information: logs, frontend and automation settings in
Setting up a time zone happens in
configuration.yaml. If you have no time zone setup, it will be auto detected using the existing detection code using freegeoip.net. You can find a list of compatible time zones on Wikipedia.
homeassistant: time_zone: America/Los_Angeles
The changes to the code are mostly backwards compatible. The old
hass.track_point_in_time use now internally two new methods:
hass.track_point_in_utc_time. The usage of the old methods have not changed and should be backwards compatible.
This refactor adds a new migration for the database adding a
utc_offset column to events and states. This information is currently not used but can prove useful in the future when we start analyzing the historical data.
All built-in components have been upgraded. The following list is only for people that run custom components:
hass.track_point_in_timewill now return a time zone aware datetime object. Python does not allow comparing a naive with an aware datetime object.
- the sun attributes for rising and setting are now in UTC. The methods
sun.next_setting(hass)are backwards compatible, just be careful if you used to read the raw attributes.
- the API sends all times in UTC. If you use anything else besides the frontend to talk to HA, make sure it handles it differently.
It’s been a month since the latest update and a lot has happened again. Here a quick overview of the new things.
Line Charts James has upgraded the history in the frontend to support line graphs. Line graphs will be shown for any entity that has a unit of measurement. The line graphs will also be shown in the more info card of an entity. See the demo for a live example.
ISY994 hub support Ryan has contributed support to integrate the ISY994 hub by Universal Devices. This allows you to integrate your X10/Insteon sensors, switches and lights.
He has created an extensive getting started guide which can be found on the ISY994 component page.
# Example configuration.yaml entry isy994:
Logbook I (Paulus) have added a logbook component. The logbook component provides a different perspective on the history of your house by showing all the changes that happened to your house in chronological order. See the demo for a live example.

# Example configuration.yaml entry logbook:
Andythigpen has contributed a script component. This allows users to create a sequence of service calls and delays. Scripts can be started using the service
script/turn_on and interrupted using the service
script/turn_off. A separate page has been added to the frontend to see the status of your scripts.

# Example configuration.yaml entry script: # Turns on the bedroom lights and then the living room lights 1 minute later wakeup: alias: "Wake Up" sequence: - alias: "Bedroom lights on" execute_service: light.turn_on service_data: entity_id: group.bedroom - delay: # supports seconds, milliseconds, minutes, hours, etc. minutes: 1 - alias: "Living room lights on" execute_service: light.turn_on service_data: entity_id: group.living_room
It has only been a little over a week since Theodor introduced YAML support for Home Assistant but so much has already happened that it is time for a summary of recent changes. Before mentioning the highlights I want to thank andythigpen, jamespcole and theolind for numerous bug fixes, enhancements and new contributions. Thanks!
Monitor local resources.
Theodor has contributed a new sensor platform to allow you to monitor disk usage, memory usage, CPU usage and running processes. This platform has superseded the process component which is now considered deprecated.
# Example configuration.yaml entry sensor: - platform: systemmonitor resources: - type: disk_use_percent arg: /home - type: memory_free - type: process arg: kodi
Experimental Z-Wave support
There is now experimental support for connecting Z-Wave networks using a Z-Wave USB stick. Right now it only integrates Z-Wave sensors into Home Assistant. Our goal is to get this tested by more people before adding support for other Z-Wave devices.
The new component is built on top of python-openzwave. This package is currently not distributed on PyPi so we’ve added a script
scripts/build_python_openzwave to install it on your machine. Alternatively you can use the Docker image which is ready to go.
The development was done using an AEON Z-Wave USB stick and an AEON Z-Wave MultiSensor.
# Example configuration.yaml entry zwave: usb_path: /dev/ttyUSB0
An initial version of voice control for Home Assistant has landed. The current implementation consists of two parts.
The first part is a component called
conversation that exposes the service
conversation/process. This service is capable of processing text and translating them into commands for devices. For now it will only support commands in the format of
Turn <Friendly Name> <on/off>.
The second part is an upgrade to the frontend to use the speech-to-text in Chrome to allow users to speak commands. If you’re using Chrome, you can test this out in the demo.
# Example configuration.yaml entry conversation:
It is well known that you are either a good programmer or a good designer. It’s rare you’ll meet someone that is both. That’s why it wasn’t surprising to anyone that the logo that I made was mediocre — at best. Luckily, Jeremy Geltman has come to the rescue and contributed a brand new logo for Home Assistant.
The new logo follows Googles material design spec. It uses the blue color that Home Assistant uses in the interface and it comes in two versions: a high detailed version (for homescreen icon etc) and a simple version (for favicon etc).
The old logo, the new detailed logo and the new simple logo.
Home Assistant is now using YAML for its configuration file. YAML allows the use of lists, which should make the configuration file a bit more flexible and useful. The new configuration file format is backwards compatible with existing components. Because of this, there is no need for component developers to update their components.
The new file is named configuration.yaml and if it can’t be found in your config directory, Home Assistant will instead try to find the old configuration file, home-assistant.conf.
The home-assistant.conf.example has been replaced with an updated configuration.yaml.example.
Users of Home Assistant should migrate as the old configuration format is deprecated.
