[mh] the persistence of memory

[David N. <dno...@ya...>]

I am using a one wire temperature sensor connected to misterhouse via =
Gregg's oxc program.  The flow of data is:=20

digitemp=20
oxc=20
xap=20
owx
analog sensor item=20
weather hash=20

I recently noticed the temperature wasn't changing and found that the =
device file that digitemp was using had changed names.  (I have a serial =
1-wire adaptor plugged into a usb-to-serial hub, and it's device files =
tend to change name depending on what other usb devices are plugged in.)

Anyway, it would have been nice to have had a better indication that it =
was broken.  It seems to me the temperature should become undefined if =
there is a problem, but I don't know where this should be done.  Maybe =
an optional feature in all items that allows you to specify a time after =
which data reverts to undefined if not updated?  =20

Ideas?  =20
