I guess it should be something like this and name the script script_time_xxxxxx.lua to do the check one time each minute:

Code: Select all

commandArray = {}
sWeatherTemp, sWeatherHumidity, sWeatherUV, sWeatherPressure, sWeatherUV2 = otherdevices_svalues[Badkamer]:match("([^;]+);([^;]+);([^;]+);([^;]+);([^;]+)")
sWeatherHumidity = tonumber(sWeatherHumidity);
if (sWeatherHumidity > 60 and otherdevices['Fan'] == 'Off') then
	print("luchtvochtigheid in de Badkamer is groter dan 60%, zet ventilator aan. " .. sWeatherHumidity)
	commandArray['Fan']='On'
elsif (sWeatherHumidity < 55 and otherdevices['Fan'] == 'On') then
	print("luchtvochtigheid in de Badkamer is lager dan 55%, zet ventilator uit. " .. sWeatherHumidity)
	commandArray['Fan']='Off'
end
return commandArray

EDIT: Updated the script to avoid setting the FAN each minute.

Had a closer look at the LUA event options for that type of device and think something like this should work as a "script_device_xxxx.lua" event:

Code: Select all

commandArray = {}
if (devicechanged['Badkamer_Humidity'] > 60 and otherdevices['Fan'] == 'Off') then
	print("luchtvochtigheid in de Badkamer is groter dan 60%, zet ventilator aan. " .. devicechanged['Badkamer_Humidity'])
	commandArray['Fan']='On'
elseif (devicechanged['Badkamer_Humidity'] < 55 and otherdevices['Fan'] == 'On') then
	print("luchtvochtigheid in de Badkamer is lager dan 55%, zet ventilator uit. " .. devicechanged['Badkamer_Humidity'])
	commandArray['Fan']='Off'
end
return commandArray

Wiki refference https://www.domoticz.com/wiki/Events somewhere in the middle of that page.

thank you very much for the time and effort!!

I'm trying to create a script, that the fan turn on when the humidity above 60% is.
I know that this script is completely wrong but I had something like this in mind:

Code: Select all

commandArray = {}
sWeatherTemp, sWeatherHumidity, sWeatherUV, sWeatherPressure, sWeatherUV2 = otherdevices_svalues[Badkamer]:match("([^;]+);([^;]+);([^;]+);([^;]+);([^;]+)")

sWeatherHumidity = tonumber(sWeatherHumidity);



if (devicechanged['Badkamer'] > 60) then

commandArray['Fan']='On'
   
end
return commandArray

I know that there are many examples, but this would not succeed me
I hope someone can help me

A while ago I had a hygrostat that was supposed to switch on the fan when a certain amount of humidity was registered in the bathroom but I ended up adjusting this threshold almost every day. On a rainy day it was different than on a cold winter's day. I ditched the hygrostat and created the script https://www.domoticz.com/wiki/Humidity_control. That registers a relative rise in humidity level and tries to dehumidify to the level just before the rise. Works like a charm. But you need a humidity sensor of course.

t1 = os.time()
s = otherdevices_lastupdate['Fan']

 
year = string.sub(s, 1, 4)
month = string.sub(s, 6, 7)
day = string.sub(s, 9, 10)
hour = string.sub(s, 12, 13)
minutes = string.sub(s, 15, 16)
seconds = string.sub(s, 18, 19)


commandArray = {}

t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
difference = (os.difftime (t1, t2))

if devicechanged['Badkamer_Humidity'] ~= nil then
   print("luchtvochtigheid in de Badkamer update: " .. devicechanged['Badkamer_Humidity'] .. " Fan:" .. otherdevices['Fan'])
   if (devicechanged['Badkamer_Humidity'] >= 65) then
   if (otherdevices['Fan'] == 'Off' and difference > 3600 and difference < 3660) then
      print("luchtvochtigheid in de Badkamer is groter dan 65%, zet ventilator aan. ")
      commandArray['Fan']='On FOR 10'
   end
   end
end
return commandArray

jvdz wrote:Maybe I am confused now but the result of your test is that the FAN will only be activated when the Humidity is higher than 65% before 1 hour is passed since the last time the fan was activated? When the humidity is only > 65% after the 3660 seconds is passed, the fan will not be activated anymore.

Code: Select all

   if (otherdevices['Fan'] == 'Off' and difference > 3600 and difference < 3660) then

Shouldn't that be that you want to wait at least 1 hour since last activation? like:

Code: Select all

   if (otherdevices['Fan'] == 'Off' and difference > 3600) then

Disadvantage will be when taking a shower, it can take up to 60 minutes before the fan is activated.
