Question

Guest muhmuh

Hello,

im looking for a HC3 Script which switch a Bathroom Fan on/off with dependency relative humindity.

I found a HC2 Script from kapitano1 (https://forum.siio.de/t/lua-taupunktlueftung-im-keller/5206)

My Lua skill is very low, so i tried to change the code to hc3 and add my ids.

The script will run correctly when humidInAbs - humidOutAbs > 1 but the switch off fan code is not correct.

And sorry for my english, but it is not my native language; i tried my best.

Can anyone correct it please?

do not forget setup Id's via variables

 

 

pressure device - optional. default is Standard sea level pressure is 1013 hPa

switch - also optional.. default only self on / off.

  • thanks for the input, but this is only humidity a suboptimal value in terms of ventilation or info to open window.  therefore the rel. Humidity is a better value. the formulas are correct and are used in other forums (homematic). it's just about how I adapt the code, that it checks when the script is running and if the value inside ist lower than outside, the code turns off the fan.

    @muhmuh If I run the script (with some fixed values to make it work for my setup and easy testing), it turns on or off the fan

    Is the absolute humidity “kg/m3” or “g/m3” instead of “%” ?

  • @SmartHomeEddy g/m³ is the absolute humidtiy.

    no errors? ok, i will restart the hc3 and will try it again.
     

    @10der I'll look at your script tomorrow when i'm at home.

     

    at the moment the script will trigger every minute and sends every minute the fan off command.

    an idea how the script only sends the off command if the script was previously running and the values are lower now ?

    V3.

     

    now you can not setup inside temperatrure and humidity device.

    just move this device to room what you want to control and this device hook your defaul temp and hum sensor automaticaly!

    V4,

     

    1) fix round for calculation,

    2) now device is driving ON / OFF mode. for example i you DO NOT want to automatical;y turing on / off your vent device simple turn off this device.

  • @10der thx u so much, i added the QuickApp and it is fantastic. I added my decive id for temp and hum inside in the code, because i have 2 sensors in the bathroom and the default sensors are the thermostat sensors not the shower sensor.

    can u also add a delay for the turnoff fan? so i can add 5 minutes for expample?

    the next test myself is, if i can stop the quick app at night with a blockscene because my fans are very loud and if they goes on in the night and my little daughter wakes up, my wife will kill me :)

    @10der

    I have a problem with the QA Humidity Controller that I do not understand.
    I take tInside ID 113 and hInside ID 114 from a Fibaro Smart Implant that has a combined humidity and temperature sensor (DHT22).


    But this QA insists on retrieving and displaying the temperature from the built-in temperature sensor (ID 112) which has a much higher temperature (31°C).

    It does not matter which ID I enter for tInside, it always shows the wrong temperature.
    The variables are written correctly, but the input is incorrect (humidity is correct). So, what is wrong?

     

    tOutside = 63 
    hOutside = 62
    tInside = 113
    hInside = 114
    pressure = 59
    switch = 130

    @RH_Dreambox IMHO I have override your ID by default sensor from room

    I use a script to measure the outside humidity level (in %). The higher the outside humidity level, the higher I set the on (and off) level of my MCO Humidity sensor in the bathroom, that works with an association with a Fan. 
     

    But sometimes the inside humidity level is more influenced by the outside humidity level and other times it is not. 
     

    Is this relative humidity of this topic more reliable for that purpose?

  • @10der can u add a delayin X Minutes, so we can config a minimal runtime for the fan?
