regulate heater with door sensors

[Guest Forall]

Please help!

I am trying to use some inspiration from

to regulate my air heather pump, What I want it to do is that when any of my doors has been open for more than 45 sec, turn off the heater and then wait untill all the doors has been closed for 45 sec before turning on again. But unfortionatly i dont get it to work and cant se what the problem is. Sadly i am yet not experienced enought with lua butneed to learn, i now have 80 scenes reulating some 73 switches and sensors.

local Doorfront = 149 -- main door

local Doorback = 50 -- Rear door

local Doorside = 52 -- Side door

local heater = 218

local heatDelay = 45 -- 45 seconds (the value is in seconds)

local heatstart = 45 -- 45 seconds (the value is in seconds)

 

-- Only allow one instance of the current scene to run at a time

if (fibaro:countScenes() > 1) then

  fibaro:abort()

end

 

local value, timestamp = fibaro:get(Doorfront, 'frontvalue')

local value, timestamp = fibaro:get(Doorback, 'backvalue')

local value, timestamp = fibaro:get(Doorside, 'sidevalue')

local value, timestamp = fibaro:get(Doorfront, 'frontvaluestart')

local value, timestamp = fibaro:get(Doorback, 'backvaluestart')

local value, timestamp = fibaro:get(Doorside, 'sidevaluestart')

if (frontvalue == '0') and (backvalue == '0') and (sidevalue == '0')then -- is the light off?

  -- the doors are closed

 

  -- keep looping until the door has been open for heatDelay time

  while ((frontvalue ~= '0') or (rearvalue ~= '0') or (sidevalue ~= '0') or ((os.time() - timestamp) < heatDelay)) do

    fibaro:sleep(1000) -- let other things happen for a second, just wait here

    value, timestamp = fibaro:get(Doorfront, 'frontvalue')

    value, timestamp = fibaro:get(Doorback, 'backvalue')

    value, timestamp = fibaro:get(Doorside, 'sidevalue')

  end

  -- the doors has been open long enought

  fibaro:call(heater, 'turnOff') -- turn off the fan

else

  -- the doors are closed

  while ((frontvalue = '0') and (rearvalue = '0') and (sidevalue = '0') or ((os.time() - timestamp) < heatstart)) do

    fibaro:sleep(1000) -- let other things happen for a second, just wait here

    value, timestamp = fibaro:get(Doorfront, 'frontvaluestart')

    value, timestamp = fibaro:get(Doorback, 'backvaluestart')

    value, timestamp = fibaro:get(Doorside, 'sidevaluestart')

  end

  

  fibaro:call(heater, 'turnOn') -- turn on the heater

end
