/* This file is specifically to cover the legacy WxGoos-II devices since MIB handling is a bit different.
 * These devices have a builtin suite of sensors as well as some optional extra sensors. This code will add
 * the builtin sensor first, and add external sensors if enumerated.
 */


#Builtin sensor resides at the below:
# IT-WATCHDOGS-MIB::climateName.1       - Name of sensor, usually "Climate Monitor".
# IT-WATCHDOGS-MIB::climateAvail.1      - Whether or not the sensor is "available".  This should always be "1".
# IT-WATCHDOGS-MIB::climateTempC.1      - Builtin Temperature in Celsius.
# IT-WATCHDOGS-MIB::climateHumidity.1   - Builtin Humidity sensor in percent 0-100.
# IT-WATCHDOGS-MIB::climateAirflow.1    - Builtin Airflow sensor (not used for this script).
# IT-WATCHDOGS-MIB::climateLight.1      - Builtin Photoelectric Cell sensor (not used for this script).
# IT-WATCHDOGS-MIB::climateSound.1      - Builtin Sound Sensor (not used for this script)

# Add-on sensors are enumerated in IT-WATCHDOGS-MIB::tempSensorCount.0 and reflect non-builtin sensors.
#   If you have two external sensors, this will return "2", with "1" being the first sensor detected and so on.
# Add-on sensor names are reflected in IT-WATCHDOGS-MIB::tempSensorName.(SensorID).
#   The return from this structure is free-text.
# Add-on sensor temperatures are reflected in IT-WATCHDOGS-MIB::tempSensorTempC.(SensorID)
#   The return from this structure is Integer.
