Staircase script with dimming option

[Dirk79]

Post your full script listing. Also enable logging for mapped object and see if they change values. Check Error logs as well.

Thanks. Here is my answer:
Sorry for not noticing the error log. There are errors:

---
Resident script:19: attempt to compare nil with number
stack traceback:
Resident script:19: in function 'setinputvalue'
Resident script:54: in function <Resident script:47>

'1/1/7' is the object of the dimming value.
I have logged 1/1/7. No logs registered.

Code:

if not client then
  timers = {
    {
      input = '9/0/1', -- binary PIR status
      output = '1/1/7', -- dimmer control (0..100%)
      onvaluehigh = 90, -- high output value in %
      onvaluelow = 10, -- low output value in %
      timeout = 5, -- in seconds
    }
  }

  function setinputvalue(timer, event)
    local value = busdatatype.decode(event.datahex, dt.bool)

    if not value then
      return
    end

    if timer.value < timer.onvaluelow then
      value = timer.onvaluelow
    elseif timer.outvalue < timer.onvaluehigh then
      value = timer.onvaluehigh
    else
      value = nil
    end

    if not timer.ticks and value then
      grp.write(timer.output, value, dt.scale)
    end

    timer.ticks = timer.timeout
  end

  function setoutputvalue(timer, event)
    timer.outvalue = busdatatype.decode(event.datahex, dt.scale)
    timer.ticks = nil -- stop timer
  end

  for _, timer in ipairs(timers) do
    timer.outvalue = grp.getvalue(timer.output)
  end

  sender = 'tm'
  grp.sender = sender

  client = require('localbus').new(0.1)
  client:sethandler('groupwrite', function(event)
    if event.sender == sender then
      return
    end

    for _, timer in ipairs(timers) do
      if timer.input == event.dst then
        setinputvalue(timer, event)
      elseif timer.output == event.dst then
        setoutputvalue(timer, event)
      end
    end
  end)
end

client:loop(1)

for _, timer in ipairs(timers) do
  if timer.ticks then
    timer.ticks = timer.ticks - 1

    if timer.ticks == 0 then
      grp.write(timer.output, timer.outvalue, dt.scale)
      timer.ticks = nil
    end
  end
end
