XONATEC HA Control for Apple TV, "How to" and "Where is" Questions

Hi, Novice HA user here, I just installed the XONATEC HA Control for Apple TV

Step 1, Success, Token Generated and copied to clipboard on Mac.

Step 2, “Create Token File”
Create a file in your Home Assistant’s www folder (or in the /config/ if the www folder doesn’t exist"

How do I do this? Where’s the www folder? the /config/ directory?
I did a lot of searching under settings, I must have missed it.
Or, am I supposed to move the appliance to my computer and USB-cable in, to find this?

I’m still a novice HA user, will highly appreciate the “How to do this.”

Many thanks !!!

Update.
Thanks to this video, I found the extra steps, and installed add on studio code server and file editor, I didnt have to use studio code server as a different youtube star did.

This video answered the “how to” and “where” missing from the documentation.
Home Assistant auf dem Fernseher Steuern for the sake of dealing with the token.

Next I had to install groups from another website.
Groups resides under settings —> Devices —> Integrations —> Helpers
after its installed.

Back to TV room. Apple TV requires 3 loaded groups to be installed,
group.hacontrol_01 thru 03. Apple TV and HA Control displayed error “No groups loaded.”
Troubleshooting —> “Try this, Try that.”
Naming the groups with and without the apostrophe punctuation didn’t work,.
Being careful to use underline instead of dash in naming, didnt help.
Restarting HA didnt help.
Rebooting Apple TV didnt help
Search engine searches went stupid and didn’t come close to a fix
Error persists

How do I make HA Control and Apple TV recognize the 3 group helpers?

Many thanks.

Hi,

========= EDIT ======= Solved =====
Groups

This does NOT work:
settings —> devices —> z-wave —> helpers

This does NOT work until you used File Edit
Developer Tools----> YAML tab —> under YAML Configuration Reloading…

This does work,

Download, Add ONs, install File Editor and Studio Code Server
Within File Editor.,…,
Folder icon up top —> Configuration.yaml
After the bottom line ie. Line 11 is where u will paste newly created file.
Use a text editor or word processor and paste the sample text into text editor.
Settings —> Devices and Services —> Z-Wave —> Entities tab
You need to look up the Entity ID on each entity, not the title,. Click on each one you plan to use and look record the exact entity ID.

Using the sample format you copied into text editor, substitute the newly found entity IDs overwriting the sample. Use spacebar to indent, not the tab key
The sample file comes from this link
Go back to File Editor, to Configuration.yaml
After the last line, paste the newly created file, back out and save.

Developer Tools — YAML tab, click check configuration.
It will puke all over you if theres a syntax error,
Otherwise, if its good, click restart and go back to Apple TV,

Hope for the best.

I hope all this will help others to not have to put in a lot of “try this, try that.”
