How do I get the uuid of a chromecast device?

[marcus13371337]

The problem

Previously (< 0.113.1), when adding a specific list of cast devices to the cast integration you were supposed to provide the ip-address to the device (by setting the host attribute in the configuration). Now when I booted up 0.113.1, I got the message that the host attribute is deprecated and supposed to be replaced by the uuid. As I have no idea how I can find the uuid of a cast device I went to the documentation for the cast integration, but I couldn't get any information on how I could find such uuid. Would it be possible to add some kind of explanation on how you could find this uuid?

Also, I noticed that the example in the manual configuration also refers to the deprecated host attribute

Also curious how to go about the same. I was initially confused by the example showing the deprecated host attribute as well. Hope someone can update the documentation and include a couple ways/best way to get UUIDs.

Any update on this? I am wondering as well.

Same. My integrations does not discover any of my 3 Chromecasts.
And none of the old configurations are working.

Hey guys! I took a dive and figured this out! Home Assistant uses a python library, PyChromecast to interact with Chromecast devices. You can see in their example that you can query for Chromecasts by friendly name, then print the resulting UUIDs.

I’m no python expert, so I wonder if there is a one-liner we might be able to use to accomplish this. I ended up using the python REPL to print the UUIDs and copied them over to my secrets file. Here are the steps I took:

1. SSH into home assistant. (You can do this on your local machine if you prefer. I used an addon that comes with a terminal and did this all from the web interface)

2. Install PyChromecast: $ pip install pychromecast

3. Enter the python REPL: $ python3

4. Type the following (replacing the list of friendly names with your actual Chromecast names):

   import pychromecast
   print(pychromecast.get_listed_chromecasts(friendly_names=["Living Room TV", "Bedroom TV", "Office Chromecast"]))

Since PyChromecast comes with HA, I wonder if we can skip step 2 by being in the correct docker container?

In any case, I hope this helps y'all along with anyone else finding this issue!

Editing to add: you can execute python inline with the -c flag. So you should be able to do something like this in lieu of steps 3 & 4 above: $ python3 -c "import pychromecast; print(pychromecast.get_....."

LEGEND!!! Can't believe the docs don't explain how to do this.

I can also confirm if you have access to the HA docker container then step 2 is not required.

Thanks for solving this issue.

I have added a pull request to the docs to incorporate this. See if it gets approved...

Works like a charm!

Mind the name is case sensitive!

Thanks for figuring this out!
