AFAIK there's no way to access the Hub variables via MakerAPI which is how HD+ gets info about every device (and it works locally and remote)
I do access a few things outside of MakerAPI -- like File Manager for uploading/downloading. They only work locally though (and harder if Hub Security is enabled).
Is there some other page which lists all variables?
That would work for a Hubitat app/driver but I'd still need to get it from a phone app (HD+). Actually, I wonder if a Hubitat app exists (or could be written) to return a list of variables and their value?
Let me know if you know of anything new here.. I did find this old post which asked a similar question I think
