Lua scene help (Leaner)

[flatfoot 0]

Hi

 

I'm very new to this.  I have a pair Fakro windows and a temperature sensor.  I'd like both windows to open when the temperature is 30 Degrees. Then have an overriding rule that the windows close 30 mins before sunset.  I've no idea where to start, can anyone point me in the right direction please?  I only bought the HC3L so it would control the windows as they often get left open at night and its a security risk if I'm away, just want to keep my family safe.

 

Hope someone can help me.

 

Many thanks

I think the scene below will do the job:

1. It triggers 30 minutes before sunset;
2. It triggers when the temperature from device with id 332 is equal or higher then 30 degr;
3. The scene checks the time, sunset and sunrise;
4. It sets the previous temp as a scene variabele and check this; else the windows keep opening every time the temp changes and it above 30;
5. I check the sourceTrigger variable who triggers the scene, the sunset or the temp;
6. When triggered I check the time, when it's 30 degr and night (between sunset and sunrise) the windows must not be opened.
7. If the temperature gets below 28 degr, reset the scene variable, to let the windows open again. I set 2 degr below 30 to prevent flipping;
8. When triggered 30 mins before sunset, close the windows.

Please change the id's of the devices in the declarations and actions field.

 

Note: I could not test this, I used my base scene I use to trigger my pool temperature sensor, that works with the same principle. If your windows stay open I'm not responsible for any damage or burglary! 

 

Create a Lua scene with the following code in the DECLARATION (trigger):
