dzVents, i don't get it at all

I find it hard to convert my lua script and really i do not get it.
For me it is way harder but that is probably because i am not a coder.
I probably need to learn this but it is not easy to do this.
I converted two easy scripts like turning on light 2 when light 1 is turned on and otherwise so that part worked.
I also succeeded to turn off a light after a couple of minutes (kids leave it on all the time)
But now i want to try to convert my ugliest and biggest script to dzVents but i am stuck in the beginning.
I create a very dirty but working script to control my mechanical ventilation by humdity or manual by a switch.
I also use a variable for that.
Now i am trying to get the humidity from the hum/temp sensor but all i get is an error.
I am able to show the readings of the sensor but there is also the temp in it ofcourse.
How do i build this?

Well, as a start you could post the dzVents script that you tried and the error you get.

Well i found this:
Code: Select all
return {
active = true,
on = {
timer = {'every 5 minutes'}
},
data = {
previousHumidity = { initial = 100 }
},
execute = function(domoticz)
local bathroomSensor = domoticz.devices('BathroomSensor')
if (bathroomSensor.humidity - domoticz.data.previousHumidity) >= 5) then
-- there was a significant rise
domoticz.devices('Ventilator').switchOn()
end
-- store current value for next cycle
domoticz.data.previousHumidity = bathroomSensor.humidity
end
}
I edited the 'Bathroomsensor' and 'Ventilator' but that doesn't do anything at all.
I found a little error where the ) after the >=5 is causing an error so i removed that.
Nothing happens with this script, no error and no turning on the ventilator.
I have a DHT22 whih measures temp and hum.
I tried setting values for the humidity and then it switches the Ventilator but that is ugly like i have now with the default lua script.

Well, you could start by printing the current humidity and the previousHumidity at the beginning of the script and see what their values are.
Code: Select all
print(tostring(domoticz.devices('BathroomSensor').humidity))
print(tostring(domoticz.data.previousHumidity))
Neither of those should be nil at any time.

I do get values now and i managed to get something switched so it is looking good.
I must say that i have a learning curve but i think i am starting to get it.

I'm curious what you find difficult and what you are missing in the documentation.

What i am missing is when you need to use which command.
For code programmers this is probably very easy and very logical.
I just sometimes need a little start and then i do not see the logic all the time.

Here i have an example:
level: Number. For dimmers and other 'Set Level..%' devices this holds the level like selector switches.
What do i use for setting a level for a selector switch?
Now i use:
domoticz.devices('Ventilatie schakelaar stand 2').switchOn()
I want to select a level for a selector switch like 20%
I also want it to go back to 10% after a minute or 2 minutes.

Well yeah. But you could start with blockly. But in the end that's programming as well. So. Programming is fun. Learn it

I don't like blockly although i use for very simple timed stuff but i am going to convert them too.
Can you tell me the selector switch part i asked? i cannot get that working and i do not understand the wiki for that part.
Thanks in advance.

If you have a selector switch you have to use the switchSelector() method.
