In your code module, instantate the Owfs_Thermostat class. Next, inform the Thermostat of the one-wire devices which control the various HVAC equipment, all of which are optional.
add_thermometer ( "<device_id>", "<location>", zone );
set_heat_relay ( "<device_id>", "<location>");
set_heat_sensor ( "<device_id>", "<location>", "<channel>");
set_cool_relay ( "<device_id>", "<location>");
set_cool_sensor ( "<device_id>", "<location>", "<channel>");
set_fan_relay ( "<device_id>", "<location>");
set_fan_sensor ( "<device_id>", "<location>", "<channel>");Usage:
$thermostat = new Owfs_Thermostat ( );
if ($Startup or $Reload) {
$thermostat->add_thermometer ( "10.A930E4000800", "Sewing Room", 3 );
$thermostat->add_thermometer ( "10.6D9EB1000800", "Kitchen", 1 );
$thermostat->add_thermometer ( "10.4936E4000800", "Living Room", 1);
$thermostat->add_thermometer ( "10.6474E4000800", "Master Bedroom", 2);
$thermostat->add_thermometer ( "10.842CE4000800", "Guest Room", 3);
$thermostat->set_heat_relay ( "05.14312A000000", "Furnace" );
$thermostat->set_heat_sensor ( "20.DB2506000000", "Furnace", "B");
$thermostat->set_cool_relay ( "05.F2302A000000", "Air Conditioner" );
$thermostat->set_cool_sensor ( "20.DB2506000000", "Air Conditioner", "A");
$thermostat->set_fan_relay ( "05.14312A000000", "Air Fan" );
$thermostat->set_cool_sensor ( "20.DB2506000000", "Air Fan", "C");
}Use this module to create a software based thermostat control which is manipulated by the MisterHouse web browser. This library module interacts with the perl cgi scripts found in code/public/Owfs_hvac.pl. This cgi script needs to be copied to web/ia7/outside/Owfs_hvac.pl. You will need to update web/ia7/outside/hvac.stml to call Owfs_hvac.pl.
Download and install OWFS from http://www.owfs.org
