Event script:

Code:

if event.getvalue() then
  storage.set('presence_time', os.time())  
end

Resident script with sleep time set to 1 second:

Code:

curr_trig_time = storage.get('presence_time', 0)

if not prev_trig_time then
  prev_trig_time = curr_trig_time
end

if curr_trig_time > prev_trig_time then
  prev_trig_time = curr_trig_time

  grp.write('0/0/2', true)
  os.sleep(5 * 60)
  grp.write('0/0/2', false)
  os.sleep(15 * 60)
end
