@oblogic7 Good work on this. I just closed my own PR because I forgot to check to see if someone else did it already. Please remember to conform the docs to your code so we can see this in the next release. ;)

Wanted to make sure I had all of the requested changes done before updating the docs. Gonna work on that today.

Documentation has been updated to match changes on home-assistant/core#13994

Could you recycle and update the config section of #5414. It's the preferred format for config schemas.

Approved by accident. :-)

[syssi]

Please update the section, too. It doesn't include the multiple device support right now.

Please rebase the docs and fix the merge conflict. Does all changes still apply?

[oblogic7]

Yes, it is up to date with all changes on home-assistant/core#13994
