changing the state of the button to switch the widget

[admin]

You will need to attach an event script to the control object (0/1/24) and create two status objects for plus/minus (32/1/13 and 32/1/14 in this example, change as needed). Then you need to attach status objects to the plus/minus buttons.

Event script:

Code:

stat_1 = '32/1/14'
stat_0 = '32/1/13'

if event.getvalue() then
  stat_c = stat_1
  stat_i = stat_0
else
  stat_c = stat_0
  stat_i = stat_1
end

-- toggle status
grp.write(stat_c, not grp.getvalue(stat_c))
-- turn off opposite status
grp.write(stat_i, false)
