This Pull Request shows in a clear way what happens if the documentation is not as good as it should be. In short, it’s about Templating and how people start to think about creative ways to solve it if it’s not documented. Let’s assume that we want the current year. There are a couple of options available to do that:

0.55: Tibber, DuckDNS, The Things Network, Owntrack

  • Release-Notes
Comments

Beside the improved Wink support which was contributed by @w1ll1am23, ships this release a wide variety of new components and platforms. The input_slider components has received a makeover by @BioSehnsucht and is now input_number. @tinloaf added a feature that allows you to enter dates: input_datetime. Both will help you to improve your automation rules.

DuckDNS

Using Home Assistant with DuckDNS for Dynamic DNS (DDNS or DynDNS) is an old story. DuckDNS is also integrated in Hass.io. 0.55 ships a component for no Hass.io users to get a similar feature.

Recorder

The purging of data was improved. With purge_interval you can schedule regular purges of older events and states. In combination you can specify with purge_keep_days the amount of days you want to keep. The new service recorder.purge allow to handle this task when needed.

Owntracks

Owntracks is an easy way to track your devices. For some times we have the device tracker which depends on MQTT but thanks to a new feature in Owntracks we can now offer support for HTTP. The new platform doesn’t require a MQTT broker but sends messages directly as HTTP requests to Home Assistant.

Tibber

This release introduces a new sensor: Tibber. The sensor provides the current electricity price if you are a Tibber customer. This will allow you to make automation for turning off the heater when the electricity price is high or only charge your electric car when the prices are low. We further plan to add support for showing future electricity prices and historic electricity consumption data. Tibber is currently only available in Norway and Sweden

The Things Network

The Things Network (TTN) is a LoRaWAN based network especially designed for IoT devices. With this integration one can observe the state of devices which are out of range of the local WiFi network as long as they are connected to a TTN gateway.

Deprecating Python 3.4 support

1 minute reading time
  • Technology
Comments

Starting with our next release, 0.55, we will deprecate Python 3.4 support. The current plan is to remove support for Python 3.4 at the beginning of 2018.

Python 3.5 was released on September 13th, 2015. It has since then become the default Python installation on the stable releases of Debian, Ubuntu, Raspbian and Hassbian. Our other own operating system, Hass.io, is more advanced and is already running the greatly improved Python 3.6.

The jump to Python 3.5 as a minimum version is driven by the Home Assistant core, which is based on asyncio. Starting with Python 3.5, asyncio got improved support in the language with dedicated keywords async and await. As this is the proper way of doing async in Python, we’re seeing a move by async libraries to either only support the new syntax from the beginning or dropping support for the Python 3.4 approach. Not moving along means an increased maintenance burden as we cannot use the latest releases of our libraries. Next to that it will prevent our users from being able to leverage the bug fixes and performance improvements that come with Python 3.5.

Hass.io

If you’re running Hass.io, you don’t have to do anything. Your system will always stay up to date.

Hassbian

If you’re running Hassbian it’s recommended that you make a backup of your configuration files and restore them on a fresh install. Upgrading an existing installation isn’t recommended.

Windows

If you’re on Windows, you’re fine as our minimum version for Windows has been 3.5 for a while now.

Other Debian based systems

If you’re running a Debian based system , follow these instructions to upgrade.

Effortless encryption with Let's Encrypt and DuckDNS

two minutes reading time
  • How-To
Comments

When Let’s Encrypt launched we were estatic: finally an easy and free way for our users to securely access their homes remotely. Let’s Encrypt signifianctly lowered the bar to get and renew SSL certificates. However, this process could still be quite an obstacle for our users. It required opening ports on the router and remembering to renew the certificate every so often.

Thanks to a blog post by Andreas Gohr I realized that DuckDNS supports setting TXT records, making it compatible with the DNS-01 challenge of Let’s Encrypt. The DNS-01 challenge is using the DNS record of the domain instead of interacting with the server. This means that it’s not needed for the user to open any ports!

I have worked together with Pascal Vizeli on updating the DuckDNS add-on for Hass.io and today we’re proud to announce it now includes automatic generation and updating of Let’s Encrypt certificates for your DuckDNS domain. The only thing that you have to add to your DuckDNS configuration is that you accept the Let’s Encrypt terms of service and point Home Assistant at the generated certificates and you’re good to go. No other work is required.

To get started today, start with making sure that you have Hass.io installed. After that, go to the Hass.io panel in Home Assistant, open the add-on store, scroll down to DuckDNS and install it. In the DuckDNS settings change “accept_terms” to true and start it.

Next up is to configure Home Assistant with the config below and restart it. You’re now good to go! Make sure to use the right protocol when browsing to your instance: https://<your_domain>.duckdns.org. Happy secure controlling your house!

# Example configuration.yaml entry for the HTTP component
http:
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem

If you’re not using Hass.io, check out the blog post by Andreas for instructions.

If you enjoy the free service provided by DuckDNS and Let’s Encrypt, consider donating to their cause:

Improved Hass.io build system

two minutes reading time
  • Technology
Comments

This is going to be a technical post for Hass.io add-on developers and people that run locally build add-ons (not the default).

Two months ago we introduced Hass.io, allowing our users to easily install, update and manage their Home Assistant installation. In this short time we’ve seen great adoption from the community. Around 20% of our users are choosing Hass.io as their method of running Home Assistant today. We’ve also seen many add-ons being made available on the forums. There are currently 14 reposities full of add-ons being shared!

Hass.io is built on top of Docker, a container runtime. One thing that Docker did not support was dynamic build environements. That was annoying for Hass.io because by supporting multiple CPU architectures, that was exactly what we needed! Luckily this feature has been added in Docker 17.05. By moving to Docker 17.05 as the minimum supported version we will be able to replace our templated Dockerfile approach with standard Dockerfiles that work out of the box. Thanks to Frenck for notifying us of this new build feature.

This change only impacts people that build add-ons or use add-ons that are built locally. You can check if your add-on is building locally on the detail page of add-ons.

If you are an add-on developer, read the documentation on how to publish your add-ons to Docker Hub. This will greatly improve the user experience.

Template changes

As an add-on developer, you will only have to change one line in your template to make it compatible with the new system. If you wish, you can also change the default build options for your image using the new build.json file.

Old:

FROM %%BASE_IMAGE%%

New:

ARG BUILD_FROM
FROM $BUILD_FROM

When

The new system will become active with Hass.io 0.64 and Host OS 1.1. Host OS 1.1 is available today. Navigate to Advanced Settings in the Hass.io panel to start the OTA update.

We have also updated our build scripts and replaced it with a builder docker engine. This builder makes deploying Hass.io components very easy. All basic functionality is supported. If you want more functionality, check out the builder by the Community Hass.io Add-ons project.

We’re approaching the end of September and that means that it was our birthday! We are now officially 4 years old and are getting more amazing with every release. This release too will include some great new stuff and tons of bugfixes. Included is a bug fix by @fanthos that should fix the frontend in some browsers. If you had issues with your browser before, make sure to check out this release.

This release we’ve started the work to make our Xiaomi integrations more robust. This meant that we’ve had to rename the components to make it more clear which of the Xiaomi protocols are being used. We have some developers working on making this very affordable home automation solution a first class citizen in the Home Assistant ecosystem, stay tuned for more integrations!

Another cool thing in this release is the new mqtt_statestream component to export state changes to MQTT. Each entity will be exported on their own topic which makes it very easy to subscribe to individual entity updates.

Comments

The Home Assistant community has been super busy in the last two weeks to bring you this amazing release. 60 different contributors have done over a 100 PRs filled with new features, bug fixes and performance improvements.

9 days away from our 4th birthday, we’ve just accomplished a couple of great milestones that I would love to share with you. We’ve hit over 8000 stars 🌟 on GitHub and starting this release we now ship over 800 platforms and components!

Customize editor

Another step in making Home Assistant configurable via the frontend has been contributed by @andrey-git: a customization editor! You are now able to inspect all (possible) customizations of an entity and update them with just a few taps. Want to change the name or icon of an entity? All possible in mere seconds.

Screenshot of the new customize editor.

New Home Assistant configurations will be created correctly automatically. If you are an existing user, make sure you have the config screen enabled and that you include customizations from customize.yaml.

# Example configuration.yaml entry
homeassistant:
  # Include the customizations.
  customize: !include customize.yaml

# Enable the config screen
config:

Tesla

Thanks to the contribution by @zabuldon, you will now be able to control your Tesla car from Home Assistant. You’re able to check the temperature inside and outside your car, control your AC and unlock the car.

Input text

This release introduces a new input component: input_text contributed by @BioSehnsucht. With this component you will be able to set free form from the UI and then let that be used by your automations or templates.

KNX

This release ships a new KNX implementation thanks to @Julius2342. It will instantly show all changed states of KNX devices within Home Assistant. Additionally it brings support for HVAC devices and notification services. It also adds a service for direct communication with the KNX bus. You can connect to KNX/IP routing and tunnelling devices. In the background it uses asyncio communication. Check the climate integration in action here and see the lights in action below:
