2021.6: A little bit of everything

A little bit of everything. That is probably the best way to describe this release. It is a packed release, with a lot of small new features everywhere!

Sonos got quite a bit of love, Hue now supports push updates, the UI has a lot of usability tweaks, MQTT added quite a few attributes, themes can now support modes… seriously, I can go on forever with this list.

So, no new big features (something might be cooking for the next release…), but a nice release that has something for everybody. Definitely worth scanning the all changes section for your favorite integrations.


Support for custom Dark mode themes

Previously, all themes automatically used our light theme as the base to build on. As of today, themes can be based on our default dark theme as well!

Not only that, @spacegaier added support for themes that can support both a Dark & Light mode in a single theme! This allows Home Assistant to select the dark or light mode of your custom theme automatically.

If you are a theme developer, you can find more information on how this works in the frontend documentation.

Oh, and of course, all your existing themes will still just work as before.

Collapsed attributes

Some entities provide quite a few attributes and those show up in the user interface. Most of the time, you don’t need to those and often contain technical data that only confuse or clutter.

To unclutter the more information entity dialog from these attributes a bit, the attributes will now show up collapsed into a bar and can be revealed with a click.

Time format settings

A couple of releases back, we added the possibility to select the number format that Home Assistant uses when showing numbers. Awesome! But… what about the formatting of time?

That question was raised a lot that release and many of you requested the same feature for time formatting, for example, if one prefers a 24-hour format.

Well, you can thank @spacegaier for this one:

You can find this new setting in your user profile.


Disable polling updates on any integration

One returning feature request, for many integrations, is adding controls for tuning the polling interval an integration uses.

For example, if an integration has an API that needs to be paid for and you don’t need too many updates, it can be a cost saver to use a slower polling interval.

Another often requested example is things like battery-powered devices, or maybe a device you only want to poll during the day and not during the night.

This release, we add support for disabling polling on every integration via the integration system options; for ALL integrations.

Wait? Disable polling?! Yes :)

So, there are many different requests on, for example, changing polling rates (also known as scan interval), but also requests for polling on a schedule, or, only based on other input (e.g., triggered by a motion sensor).

Therefore, we decided to provide the maximum flexibility for any use case you can come up with. Disabling polling makes Home Assistant stop polling automatically. However, you can use the homeassistant.update_entity service on those entities to trigger a poll for information.

This means, once you’ve disabled polling for an integration, you can create automations and completely customize when you poll that integration from that point on. All based on your own schedule, conditions or triggers.

Network integration

This release adds a new Network integration, created by @bdraco, to help other Home Assistant integrations to get the right information about your network.

It also provides you a single place to tell Home Assistant about your network. It is an advanced feature and thus will only show up if you have advanced mode enabled on your user profile.

You probably don’t need to change these settings, by default, Home Assistant will auto-detect the right configuration. However, if you have a more complex network configuration, with multiple network adapters or VLANs, you can now select the interface Home Assistant integrations should use.

Please note that this is a new feature that needs to be implemented/used by other integrations. At this point, not all integrations will honor these settings yet.

We welcome the following new integrations this release:

This is a companion discussion topic for the original entry at https://www.home-assistant.io/blog/2021/06/02/release-20216/

Great job as always !
Can we expect UI performance improvements with the migration to Lit 2.0 ?

Time to install the new version and I have to say, lately upgrades don’t cause much issues (of course if you read the breaking changes ;-))

I saw some multicast support for ZWaveJS checked in. Is that available in this release, and how to access that service?

there is an error in the link for bosch smart home controllers. a _ is apparently missing.
it’s only https://www.home-assistant.io/integrations/boschshc/, not https://www.home-assistant.io/integrations/bosch_shc/

I can’t seem to see the update show up on my instance. Is this normal? Usually, I’ve seen it available quickly.

Ooh, I love the VLAN support. Does this also work with addons? My desired config is having the Unifi addon running via Unifi management VLAN and all the rest on the Home Assistant box on an IoT VLAN.

It always takes a bit to roll out to all devices. Best you can do is keep refreshing. Mine just showed up moments ago.

After installing the new version the integration alexa_media_player disappeared

Good catch. It is fixed now (might take a little bit to become visible though).

Great release, thank you!

Will it also be possible to disable polling for the integration “RESTful Sensor”. I can’t see this option for this integration.
I think it’s currently only possible to disable the polling, if the integration is visable in the UI.

Does the time format setting “Use system local” solve this feature request?

Or is it (as I suspect) only the format, not the value from the server local used?

A huge THANK YOU to @djtimca for all of your awesome work on the Omnilogic integration!

Why did you remove tensorflow?

Looking good here. Thanks developers and others involved.

Agreed. Devices/entities are there but the integration pane is missing from the UI.

hass-variables NOT working after the 2021.6.0 update

Any solution?

Read the almost most recent issue? There is a solution mentioned.
