Bath room ventilation

[vanni177 0]

Hi Folks,

 I would like to run my bath room fan 3 min. after I entered the room.

(that is no problem) 

(The trigger sensor is a Motion Sensor)

But, If I leave the room within the 3 min the fan should not start at all.

 

Has anyone a suggestion for it 

 

Cheers

You've got a timewarp issue here

 

if you enter the room, the fan needs to start, but if you leave it shouldn't have started, when you entered.......

 

I measure humidity in the bathroom and when it increases I start the fan. When it's down to normal levels I switch it of

ha ha 

lets put on this way,

the fan is not for the humidity but for some bad human smell

Have you tried setting a scene for this?

[vanni177 0]

yes,

but I'm struggling to stop/kill the scene if I leave within the 3 minutes

any suggestion is very welcome

I tried tweaking another code I have. (I'm not pro at this coding stuff)

Perhaps this can work. remember to change the values of the modules.

You start a blocksceen at once the motion eye recognized a movement. This is delayed with 3 min.

Then you have to decied when it should stop, because you also start the stop command at the same moment, lets say delayed with 5 min. The fan runs for 2 min.

 

But you better run a smell trigger because not every entry is worth a fan.

[ggoetz56 9]

Ok I read it once more (smell trigger isn't needed).

You start a blocksceen starting the fan at once the motion eye recognized a movement. This is delayed with 3 min.

 

You have to control the sleeptime of the motion trigger. Let say movement within 10sec after getting hot are ignored.

 

New blocksceen

Then you stop the fan delayed with 2 min. When you stayed just 1 min. No fan action. When you stayed 2 min - 1min fan. When you stay 4min 3 min fanaction.

I hope the location have only one door.

maybe use global variables.  And use a wait command to check for motion.

Have you thought about using a door sensor to check if door has been closed for 3 minutes then fan is turned on? It might be easier to do this rather than use a motion sensor as you would get less false triggers

Thanks for you comments, and suggestions, I will play with it and let you know what comes out 

[vanni177 0]

emielstroeve is right, it's a time-warp. 

 

I tried a lot of different ways, but it always comes up that there is no trigger when I leave the room.

So, for time being I made a button on the phone for it; may be later I will sponsor "The Button"

thanks for your suggestions

cheers

Hi @vanni177

 

I will soon have scene that will do what you need it to do, so start fan in bathroom only if you stay long enough, otherwise will not start. Actually it will do more than just that time-warp problem

[devfern24 10]

I have a scene set up to do this for bathroom lighting, working with a door sensor and a motion sensor.

 

Is the light switch in the bathroom on your Zwave network? It could be used as a trigger to kill the scene upon leaving the bathroom.

Hi @Sankotronic

that would be perfect , please let me know.

[Sankotronic 2,370]

Hi @vanni177, will do soon. At moment I'm busy with VD for Smarter coffee. Finally our Angelina (our HA has name) will be able to prepare coffee in the morning for my wife and me!! Meanwhile testing smart light scenes and look pretty good.

Hi, I found an acceptable solution for my fan.

It will be triggered by the light, (not the motion sensor). In the same time a variable will be set and the delay time starts. If the delay time is over the fan starts only if the light is still on.

This prevents the fan to be on if you only short in the bathroom.

 

It may help someone too.

For me it's good enough 

 

The code is like:

 

--[[
%% properties
320 value
%% events
%% globals
--]]

--BG_Fan_ON ID 121

--print(os.date("%c, Start"))

local startSource = fibaro:getSourceTrigger();
local a
a = 0
--print(a)

if (
    (tonumber(fibaro:getValue(320, "value")) > 0)            --Light WC
    )
  then
--  print(os.date("%c, Light is ON"))
  setTimeout(function()
--      print(os.date("%c, delay time done"))
      a = 1
--      print(a)
      if (
          (tonumber(fibaro:getValue(320, "value")) > 0)        -- Light WC
          and a == 1
        )
        then
        fibaro:call(321, "turnOn");                           --Fan WC
--        print(os.date("%c, Fan ON"))
      end
    end, 3*60*1000)                                            --delay time
  end

Hi @vanni177,

 

I'm glad you found solution. I also did write

that can start any device after light is turned on longer than some specified time just forget to come back here and leave a post.

Hi,

 

I fix this one for my bathroom and it is working fine.

It turn on my fan only when the light is on for 2 min, and the fan stops after 5 min.
