I have been optimizing my DMX scripts for the LogicMachine. The following is a set of functions that will enable you to turn a set of DMX channels on/off.

-- set of variables for zones in the apartment
 alllights = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24}

 bathroomlights = {7,8,20}
 livinglights = {5,6,9,10,11,12,14,15,16,17,18,19}
 kitchenlights = {13}
 bedroomlights = {1,2}
 entrancelights = {4}

-- turns DMX stripe to full on or off based on two groups
function dmxtoggle(channel, state)
 -- group that contains the value for ON
 on = grp.getvalue('5/7/17')
 -- group that contains the value for OFF
 off = grp.getvalue('5/7/18')
 if (state == true) then
  DMX.set(channel, on)
 else
  DMX.set(channel, off)
 end
end

-- loops through all lights
-- lights is an array of the channel(s) to be set
-- state is the state of the group
function dmxlooptoggle(lights, state)
 for index, value in ipairs(lights) do
  dmxtoggle(value, state)
 end
end

--Loops through an array of channels and sets them to a value
function dmxloopset(lights, value)
 for index, channel in ipairs(lights) do
  DMX.set(channel, value)
 end
end

To use it, create a user library, I called it mydmx. Then copy/paste the above code and change the variables to the light groups you want to switch together.

To then run it use the following code. The first line enables the above user library. Then the dmxlooptoggle is called to change the bathroom light to the value of the group (on/off). the last code updates a group that holds the status object (on/off).

require('user.mydmx')
dmxlooptoggle(bathroomlights, event.getvalue())
grp.write('5/7/24', event.getvalue())
