LGTM 🎉

[rutkai]

Is it going to be merged in the near future? The version I wrote in the documentation is the next one. :)

You could use that from const.py by core and that helps user because all configs look the same.

Hi @rutkai,

This platform is no longer working in latest HA release 0.100.x. See Issue 27722.

Can you have a look to see if you think it can be fixed or if we have to consider removing it from HA?

Thanks
