[RE-wrenches] 0% on FNDC readings yesterday and today

[Jerry Shafer]

Oddly enough l have a few with blue planet doing this same thing, in the
past l get the batteries fully charged then reset the FNDC but if this is
more global then a possible SW update may be it but l dont think it would
do that.
Funtimes
