I wonder if questions like this might now be more appropriate to the green@ietf.org
WG mailing list given how that one seems to be mostly around instrumenting
routers with such measurement options. Cc'ed.

Which router product/model are you using , and which MIB OIDs are you using ?

I remember from the past routers with separate environmental support hardware,
so i would not want to exclude that there may be different sources of truth.

Cheers
