I thought of another possibility. Your rrd configuration may somehow be be
non-standard so AVERAGE has no data to fetch.
Try `/usr/local/bin/rrdtool fetch <file> AVERAGE --start now-800 --end now`
and `/usr/local/bin/rrdtool fetch <file> MAX --start now-800 --end now`
and `/usr/local/bin/rrdtool fetch <file> MIN --start now-800 --end now`

phpweathermap is running rrdtool fetch to get the data. From your debug, it is
retreiving the nan's:

It must not be reading the same rrd file that smokeping is using. Check the
datadir configuration option in your smokeping config file to see if the path
is the same.

Addendum...
BTW, here is my phpweathermap node config:
NODE node09727
LABEL Latency {node:this:bandwidth_in:%d} ms / Loss
{node:this:bandwidth_out:%d}%
TARGET
gauge:/www/phpweathermap/htdocs/fs_smokeping/Network/switches/sw-mm2sqpk.rrd:median:loss
USESCALE pingloss in
POSITION 153 76
Thank you,
