# plugin must be linked as climate_FQDN_VAR, where FQDN is that

#  of climate server and VAR is the variable (temp, rh, air, light, sound)

#  you wish to retrieve

# eg climate_mycm2.foo.com_temp

# HOST is the hostname of the climate server, must be in /etc/hosts

HOST=`basename $0 | cut -f2 -d_`

# VAR is variable to grab (temp, rh, air, light, sound)

VAR=`basename $0 | cut -f3 -d_`

# it will retrieve and make available five data,

#  temp (Temperature), rh (relative humidity), air (Air Flow), light

#  (Light Level) and sound (Sound Level)
