I'll keep listening to see if anything develops.

Hi George
=20=20=20=20=20=20=20=20=20=20=20=20=20=20
I did email Justin and enquired about being able to send =
out the temps in F , He indicated that the pic didnt have enough code
space=

reinheit reporting that warranted him looking into it.....I think the code

space issue could be taken care of using a pic 16F88 chip which is a 4k
dev=

I also requested Steve to have a look at xpltom10 and see if he could imp=

If i ever get my probe temp systeming up and running i would be more than=

Frank,

Have you ever heard whether the TOM10 will be able to read temps in F d=
egrees?

Hi All
Thought i would mention a little project i have been working=
on for=20
a few weeks now..
I  currently use the TOM10 board for temp sensing, but thought it wou=
ld be=20
nice if my Probe system could also monitor temp sensors as well as vi=
deo +=20
led probes....This would save me a cat5 cable in each room ..as i hav=
e a=20
probe zone box currently in each room

First thing i did was surf the net for some asm pic code for the dall=
as 1820=20
1 wire temp sensor.
After a frustrating two weeks and trying  bits of different codes  i =
have=20
managed to get my probe system to read the temp sensor...At the momen=
t=20
though it  only has a tolerence of .5degree but hopefully down the tr=
ack i=20
can mod the code to get it down to 1/10 degree.....

Some resistor changed was  required in the Probe zone box ( and also =
the=20
probe hub) , my intension is to make probes 5+6 of each zone box a te=
mp=20
probe  OR standard probe input ..The probe hub will auto detect if a =
temp=20
sensor is present....

Next is to order some dallas 1820 sensors and mod my  probe system an=
d  try=20
it out ...Still a bit of work to be done............

Tonys xPL-PROBE plugin might require a slight mod as can be seen by t=
he=20
captured message below it reports the temp as status rather than=20
current.....

xpl-stat
{
hop=3D1
source=3Daec-probe.test
target=3D*
}
probe.basic
{
zone=3Dtest5
probe=3Dprobe5
status=3D20.5 c
}

More Soon
Frank
