Hi Kim,
I’m still on 1.8.3 (never change a running system 
) so I can’t say. But you can just use the file as is. If Yahoo/the binding delivers something unknown you should see a “-” in your sitemap. Then grep your openhab.log for “no mapping”(not 100% sure here, might need some adjustment) and add whatever it complains as missing to the file. It did this quite often when i put the file together, but there was no need to do so for month now.
By the way, there is a version of this file spiced up with nice unicode symbols here:
HTH,
