[mh] xPL Help

[Andy M. <myi...@st...>]

Hi All (and Greg Liming - in particular!),

  I am trying to interface my newly written xPL HVAC Gateway (for my 
newly built AirCon Zone Controller!) to MisterHouse.

  The problem I am having is trying to setup MH to extract the data from 
the HVAC Schema. My schema is standard (well, maybe a little extra info 
- but nothing missing).

  The main difference from many schema (eg. sensor.basic) to hvac.basic 
is that "zone" is the equivalent to "device". I need to tell MH to 
differentiate on "zone", not the usual "device".

  So, my code is:

$xpl_AirCon_Zone1 = new xPL_Item('mandoon-gateway485.arwen');
$$xpl_AirCon_Zone1{'state_monitor'} = 'hvac.zone : hvac-mode'; # noloop
$xpl_AirCon_Zone1->device_monitor("zone = 1");  # noloop
$xpl_AirCon_Zone1->tie_event('print_log "AirCon: Zone 1 - state=".$state');

  The problem is that MH is ignoring the device_monitor() setup. In 
debug mode, it appears that there is no device monitor restriction set - 
unlike other xPL items setup via MHT tables.

  Presumably, my call to device_monitor() is wrong. Looking at the MH 
code, I can't really see the correct way (yet).

  Greg, or anybody else, could you quickly point me in the right direction?

  Greg - Are you interested/have time in writing some extra code to 
support HVAC table entries similar to xPL_SENSOR??

Thanks in advance,
Andy.
