Help example on simple light controll, lux

[admin]

Try this (untested):

Code:

min = 10
max = 100
hysteresis = 20
delay = 0.1

lights = {
  { active = '0/0/211', current = '3/0/11', setpoint = '3/1/11', status = '2/4/11', output = '3/3/11' },
  { active = '0/0/212', current = '3/0/12', setpoint = '3/1/12', status = '2/4/12', output = '3/3/12' },
}

function lightcontrol(opts)
  if not grp.getvalue(opts.active) then
    return
  end

  local current = grp.getvalue(opts.current) -- Area Lux Value
  local setpoint = grp.getvalue(opts.setpoint) -- Area Lux Setpoint Value

  if math.abs(current - setpoint) < hysteresis then
    return
  end

  local status = grp.getvalue(opts.status) -- Status dim value
  if status == 0 then
    return
  end

  local diva_up = math.min(status + 5, max)
  local diva_down = math.max(status - 5, min)

  if current < setpoint then
    grp.checkwrite(output, diva_up)
  elseif current > setpoint then
    grp.checkwrite(output, diva_down)
  end
end

for _, light in ipairs(lights) do
  lightcontrol(light)
  os.sleep(delay)
end
