OK, Maybe I'm dense. Or maybe I'm still programming at 01:30, but I can't
make sense of this:
I have 3 device serialnumbers in a database. I want to check to see if
they are really there. Seems straightforward, right? This is a bit of my
code:
#Check to see if we really have the device, or it's just in the DB
if ($owserver->present("/$serialnum"))
{
$sensors{$serialnum}->{sensorid}=$sensorid;
$sensors{$serialnum}->{sensortype}=$sensortype;
$sensors{$serialnum}->{name}=$name;
$sensors{$serialnum}->{calibmult}=$calibmult;
$sensors{$serialnum}->{calibadd}=$calibadd;
}
else
{
print "$serialnum not found. Skipping.\n";
}
I never see the 'not found' even though I only have 2 devices currently on
the bus. Now, I run my code, and it reads all the devices, and I have it
print out the unixtime, serialnumber, and values to stdout right now. This
is what I get:

Now, how is the 26.9A device showing up when it's not there?
