Home Assistant OS 11: Low-latency scheduler and VM snapshot improvements

With Home Assistant OS 11, there is no big or flashy feature to highlight. Rather, there are a lot of small improvements and little gems. The increased use of Bluetooth has uncovered quite some issues on Home Assistant OS; some of which we are still working on. One of the main issues in Home Assistant OS 10 was caused by a bug in the processing of Bluetooth advertisements in the Linux kernel’s Bluetooth stack itself. With the help of our community, we managed to reproduce, pinpoint, and provide the necessary hints to the Bluetooth developers. This led to a fix in the Bluetooth stack not only for Home Assistant OS and Supervised users but for the Linux community in general 🎉 (see issue https://github.com/home-assistant/operating-system/issues/2535 for details).

We’ve also worked on the landing page which is bundled with Home Assistant OS 11. The landing page is visible to the user when starting a fresh installation of Home Assistant OS for the first time. It features the same new look as the Home Assistant Core onboarding flow, and tracks issues during the bootstrapping phase, automatically displaying errors if they occur during that critical setup phase.

This month we at Nabu Casa got a new addition to the Home Assistant OS team: With Jan Čermák joining, we will have more bandwidth to implement new features as well as to tackle issues reported by our community. Welcome Jan!

And finally: Home Assistant OS 11 will be pre-installed in the next batch of Home Assistant Green 🎉

Enjoy the latest version of Home Assistant OS!

Removal of Mazda Connected Services integration

On October 11, 2023, we were informed that an open-source contributor received a cease and desist letter from Mazda North American Operations (Mazda) regarding his library to connect with Mazda services. This library was used by the Home Assistant integration Mazda Connected Services, which he also maintained. A DMCA notice was sent to GitHub requesting the removal of all code and forked repositories as well.

The contributor has complied with the cease and desist letter. The library is no longer available, and the Mazda Connected Services integration has been removed from Home Assistant in the 2023.10.2 patch release of Home Assistant released on October 12, 2023.

Home Assistant is disappointed that Mazda has decided to take this position. We’re also sad that Mazda’s first recourse was not to reach out to us and the maintainer but to send a cease and desist letter instead.

We invite Mazda to speak with us about this topic. We would love to have an open and constructive discussion about the potential that a Home Assistant integration has for them and their customers. We genuinely believe there is a common ground between us and Mazda when it comes to enabling the owners of their cars to explore the possibilities of their own data.

After all, other car manufacturers do see this potential. For example, Tesla has recently released official API documentation to support third-party apps. Volkswagen Group’s Audi brand has launched an app store in their cars that features the Home Assistant app. We hope Mazda will see this potential, as well.

Year of the Voice - Chapter 4: Wake words

This year is Home Assistant’s Year of the Voice. It is our goal for 2023 to let users control Home Assistant by speaking in their own language.

We’ve got great news: wake words are finally here! After 4 chapters, we now have the final building block for voice in Home Assistant.

In Chapter 1, we started with text commands such as “turn on the kitchen light” and “open garage door”. We now support 56 languages and have 188 contributors helping to translate common smart home commands for everyone.

Chapter 2 introduced audio for voice commands: both speech-to-text and text-to-speech. This included local options for maximum privacy as well as support for Home Assistant Cloud for incredible speed and language coverage. Lastly in Chapter 3, we added the ability to set Home Assistant as your default assistant on Android phones and watches.

For Chapter 4, we’ve now added wake word processing inside Home Assistant. Wake words are special words or phrases that tell a voice assistant that a command is about to be spoken. Examples are: Hey Google, Hey Siri or Alexa.

Home Assistant’s wake words are leveraging a new project called openWakeWord by David Scripka. This project has real-world accuracy, runs on commodity hardware and anyone can train a basic model of their own wake word in an hour, for free.

To try wake words today, follow our updated guide to the $13 voice assistant.

2023.10: New looks and more tile card features!

Home Assistant Core 2023.10! 🎉

October! 🎃 It means we’ve just celebrated our birthday; we are now 10 years old! 🎂 In case you’ve missed our birthday YouTube stream with all the cool announcements, we’ve summed it all up in our 10 year Home Assistant blog post.

Even more exciting news, as this is Home Assistant’s year of the voice: Chapter 4 of this endeavor has been announced and will be streamed live on YouTube on 12 October 2023, at 12:00 PDT / 21:00 CEST! Be sure to tune in! I’ve seen some early demos… All I’m going to say is: It is mind-blowing! 🤯

As for this release, because of all of the above, it is a bit smaller than usual in terms of features. I promise that chapter 4 is going to make it all worth it. Yet, it contains tons of updates, bug fixes, and a couple of beautiful new features for the tile card! 🤩

Enjoy the release!

[Update Oct 2: data sharing to become optional] Philips Hue will force users to upload their data to Hue cloud

Update Oct 2: In a conversation with The Verge, Philips Hue has announced that they will update their privacy policy to require users to consent to share their usage data with Philips Hue.

Original Post

Today’s story is about Philips Hue by Signify. They will soon start forcing accounts on all users and upload user data to their cloud. For now, Signify says you’ll still be able to control your Hue lights locally as you’re currently used to, but we don’t know if this may change in the future. The privacy policy allows them to store the data and share it with partners.

Last week I wrote how toying with the first Philips Hue hub and their local API led me to start Home Assistant back in 2013. They have played an important role in my smart home and they were a role model for our Open Home vision. Sure, they are expensive but they work reliably, have a local API, can be used completely offline, and you don’t have to share your data with the cloud.

But things are changing, for the worse. When you open the Philips Hue app you will now be prompted with a new message: Starting soon, you’ll need to be signed in.

Introducing Home Assistant Green: Your entry to Home Assistant

Back in 2021, we launched a crowdfunding campaign for Home Assistant Yellow. Home Assistant Yellow was our take on what a smart home hub should look like, with all the features we enthusiasts want. We’re very proud of Home Assistant Yellow, but at the same time, it has become clear that people just starting their smart home journey don’t need all the features Yellow offers. With the global component shortages making the required Compute Module 4 more expensive and harder to find, Home Assistant Yellow is no longer a good fit for beginners.

We’ve taken that to heart, and today, we are introducing an affordable way for new users to upgrade their smart homes to Home Assistant. It’s the Home Assistant Green – and it costs only $99 (MSRP).

A refreshed logo for Home Assistant!

The new Home Assistant logo on a blue background.

Hello all, this is Madelena. You may know me from some of my previous projects. 🙂

As you may have heard from our celebration for the 10th anniversary of Home Assistant, we are making some tweaks to our logo! This is no small feat, as the logo is a big part of the identity of Home Assistant, and by extension a representation of the contributions of our community. This logo has served us well for 8 years. When we see the logo, it represents the culmination of work that we are all proud of.

2023.9: New climate entity dialogs, lots of tile features, and template sensors from the UI!

Home Assistant Core 2023.9! 🎉

Frenck is enjoying a well earned holiday, so I’m taking care of the release this month.

This month, on the 17th, it has been 10 years since Home Assistant started. We’ll be preparing a special event on the Home Assistant YouTube channel to celebrate, reflect and look ahead. We will have some cool announcements too! We hope you can join us on the 17th @ 12:00 PDT / 21:00 CET!

This release is pretty packed! With some very nice updates to the UI with new entity dialogs for climate entities, and lots of tile card features. Template sensors can be created from the UI now, and for the more advanced template sensors, the ability to get data from services! A new service to get the weather forecast, and better options to display different forecasts.

And something you will probably not see when you are already using Home Assistant: the onboarding flow is completely redesigned!

I absolutely love it!

Enjoy the release!
