??Vars held in the settings dict (gv.sd), default values shown

from controller values (cvalues):
en:1	enabled (system operation)
rd:0	rain delay (hours)
mm:0	manual mode (bool)
rbt:0	reboot (bool) 

from options:
htp:8080 http port the program will use
seq:1	sequential/concurrent operation (bool)
sdt:0	station delay time
mton:0	master on delay
mtoff:0	master off delay
nbrd:1	number of boards (includes base unit and expansion boards)
tz:16	time zone -- no longer used by the program as of v2.0
tf:1	time format (24 hour clock == 1)
urs:0	use rain sensor (bool)
rst:1	Rain sensor type (normaly open=1 (dafault), or normaly closed=0)
wl:100	water level (percent adjustment of watering time)
mas:0	master station index
ipas:1	ignore password (bool)
pwd:"b3BlbmRvb3I=" encoded password (default 'opendoor' shown here)

rdst:0	rain delay stop time (unix time stamp)
rs:0	rain sensed (bool)
nopts:14 Number of optiions to be displayed
name:"SIP"	configurable name for system
snlen:32 max size of station names

for scheduling:
bsy:0	program busy
nprogs:0 number of programs (can be calculated form length of prog array)
mo:[0] master operation bytes - contains bits per board for stations with master set
ir:[0] ignore rain bytes - contains bits per board for stations to ignore rain delay and rain sensor
iw:[0] ingore water level - contains bits per board for stations to ignore water level (both general scaling and plugin adjustments)
rsn:0 Reset all stations
nst:8 number of stations
radiost number of radio stations (included in nst count)

for logging:
lg:0 log runs if = "checked"
lr:100 limit number of log records to keep, 0 = no limit

for substations:
master:0 this station is operating as a master
slave:0 this station is operating as a slave
master_ip:'' ip address of master (only valid if slave != 0
substation_network: name of private network for master and slaves
