Re: [mh] Weather questions

[Robin E. <ro...@ji...>]

Strange, I think I know what the problem might be, but I find it hard to
believe.  Can someone who has better understanding of Perl than I help
me by looking at the code.
It could be in weather_wmr968 or in the rrd code.  The one thing I know
is that temperatures make it to the summary line ok.  However, it
appears that when the outside temp goes below zero I no longer get temp
data(inside or outside) appearing on the graphs.  We've had some
reasonably cold weather in the UK recently and every time it goes above
zero I get entries on the weather graphs, once it dips below nothing.

This only seems to impact temperatures as everything else reports correctly.

regards, robin
