Nice indeed.
Wow this is so awesome! Thanks for suprising us time and again with these cool solutions & Happy birthday!
Happy Birthday! Nice work!
Thats awesome.
Happy Birthday
Happy birthday! sounds like a nice feature!
I’d like to add to schmurtz question:
Can you also see a live stream as soon as an event is triggered?
Happy birthday Paulus. Have a good one. Glad you got this going 5,5 years ago!
Happy Birthday, sir!!!
This is beyond awesome, hope to try it out ASAP.
Looks cool, I haven’t quite come around to having mics installed all over the house … yet so no Google (stealing? the name) Home Assistant here yet.
But that functionality (beyond the GHA), isn’t that just what I already have with my old Surface Windows tablet/PC and Chrome + my HA??? Just with all the Windows world incl…
Still not convinced I need the GHA, Alexa, Samsung TV remote+MIC, Sonos+mic etc. The cloud is a thing I try to avoid with my HA as much as possible.
Happy birthday, damn sounds like a awesome feature, can’t wait to play with it!! 
Happy Birthday!
If this feature came to HA i would maybe buy at least one of these, but even without it, home assistant is so amazing!
It won’t require a subscription. Your Home Assistant instance will need to be accessible outside of your network if you want to cast to a Chromecast outside of your network (as the Chromecast needs to talk to your instance)
It only took long to load because I synchronized it with the story. As soon as it said connected it could start showing a UI.
And to to run it from the Google Nest itself, you should be able to expose a Home Assistanr script via the Smart Home integration of Google Assistant that will open Home Assistant Cast.

Happy Birthday Paulus and thanks for all the hard work you have and are doing.
My house will never be boring thanks to Home Assistant. 
This is awesome! Actually makes the Google/Nest Hub worth it. I have one, and was kind of disappointed by the lack of usable features that the screen brings vs a regular assistant device. Happy Birthday Paulus
maybe a stipid question, i dont own a “hub” yet, just some mini’s
but if you cast a screen to it, so you are actually using another frontend, can you still use GA on it?
does it still accept voice commands when GA is in background?
Guys you can see my implementation here if you don’t want to wait. As far as the home hub is concerned it’s just another casted stream like any other so the hub behaves as normal
This looks very cool! So if I use a Xiaomi button as my doorbell, as I currently do I would think that it would be possible to have my camera turn on a live stream on a television that had a chrome cast hooked into it? Correct?
If so I may have to invest in one soon! That’s for all you and the team do! I love HA and everything it stands for! May thanks my friend!
Cant wait for a tutorial on how to use this!
This is so cool! This kind of stuf is why I love Home Assistant and the community so much.
excited for tomorrow’s beta release
Is balloob going to be in the next Macklemore music video?
That looks very interesting. Great idea to be able to trigger a cast to a screen in case of an event (like the doorbell you mentioned).
Is it possible to cast different Lovelace screens to different hubs? So every room is personalised?

You can with the method I’m using (though it currently requires the use of a second Pi).

Awesome! Can’t wait. Happy birthday!!
Basically you need to install “cast all the things” on a second pi which you can use to cast any URL. Use a command line switch with SSH to connect to the other Pi and trigger the catt. If you want to use Lovelace you’ll have to enable trusted networks auth and allow the IP of the device you’re casting to as it’s not possible to type on the Google home hub to enter login details.

Thanks for working on this. I’ve been pestering Google to allow webpages to load on the smart display https://support.google.com/assistant/thread/232545?hl=en for over a year now so I can use Home Assistant on the Smart Display.
Can’t wait to get this working!!!
Because you can’t install the required catt on the hass.io pi unless you potentially set up another docker container which isn’t something I’ve looked into
scratch that, you can just use portainer to install catt directly into the home assistant container.

Because of you I might not return my Google/Nest Home Hub after all. If you can implement the possibility to view the “Plant” (MiFlora) enteties on my Hub I would… well. I don’t know if a kiss from me is worth much to you… but I could send some cash for a beer or five in your direction! 
Yeah but it’s by far the easiest method of installing catt rather than another pi etc and would take 2 seconds to reinstall it.
Not yet released but if you run the code before it’s released you should be able to do it. See post 4

How can I use it, at the moment? Where do I have to place this files?
Hell yes!!!
Smart displays are finally useful! Do you think we could get it early if we pay or is it not ready? I would be willing to pay a patreon or something I have home assistant cloud. Thanks
If not maybe a automation?
Theoretically it is possible, but they likely won’t
So should we use home-assisant-cast branch from pychromecast for and cast branch from home-assistant-polymer?
This is great It works perfectly on my nest Hub, anyone knows an automation to keep always casting? i Tried tô watch YouTube Just to teste and when returned It stopped casting home assistente.
Did this stopped working for everyone?
I can’t get this to work at all. And strangely nobody has mentioned it or said anything about why it fails to work.
I can cast from my laptop to my chrome cast with no problem but can’t setup automations to do so.
My fingers are crossed this eventually gets looked at by somebody that knows what they are doing…
Is this effort dead?
not as far as i know.
I use Home Assistant Cast to cast a Lovelace view with a single and very simple entity card to my Samsung 46 inch TV via a Goggle ChromeCast device. Everything works, except for the fact that the result on my TV is a tiny card with a lot of white space around it. The card fills less than 1/4 of the screen and it is centered at the top of the screen.
In reality, this is useless cause one cannot read the text from a normal viewing distance.
Is there a way to make a card fill the whole width of the screen ?
I have a feeling that changing the resolution of the ChromeCast would solve the issue, but regretfully, that’s not possible.
