Hi,
There is no central register to assign UIDs rather they should be up to
the installer to configure. The main reason for this is that a UID must
be unique on a network and if there were multiple copies of an
application running you would need to pre-register a large block of
UIDs, not really a practical solution. The normal way to deal with them
is set the UID to a random hex number at install and give the user an
option to change it later if needed. Your example header looks fine btw.
I notice you are planning on using the pc.status schema. Let me know if
you require any expansions to it. I remember when we last spoke some
additions were made but more can be added.
Guessing the first few feature requests that may well be asked. Firstly,
making the interval between sending of pc.status messages customisable
and secondly the sending of a display message when an alert/alarm happens.
The message schema is here:
http://www.mi4.biz/modules.php?name=Content&pa=showpage&pid=9
and an
example message would be:
xap-header
{
v=12
hop=1
uid=FF671100
class=PC.status
source=almico.speedfan.officepc
}
Display.Text
{
Line1=CPU has got hot
Line2=It is now 100C !
Priority=1
Duration=30
}
and with that your Squeezebox, IM client, PC, LCDs.. would show it. So
you'd never miss an alert again!

I'm going to add xAP support to SpeedFan. SpeedFan is a Windows <br>
hardware monitoring tool that can read temperatures, fan speeds and

voltages in a PC. Is it correct if the xap-header sent by SpeedFan
is:<br>
<br>

}<br>
<br>
?<br>
<br>
Or should I force the user to configure by hand the "6711" part
of <br>
the "FF671100" UID in order to ensure unicity?<br>
<br>
Thank you.<br>
