How to schedule a program to run between two dates every year

[ArunGupta2014]

I have just purchased a ISY994i/IR PRO + 2413S PLM. Needless to say, I am impressed with the capabilities of the system.

 

As I am learning to create programs, I have a question:

 

I want to program an outside light to turn on at 3:00 AM and turn off at 30 minutes before sunrise but only between 11/1 and 3/31 of every year. How would I do this?

 

Thanks,

Arun

The ISY, to my knowledge, remains without this native capability. One of the crazy-good members has written a program using variables to keep track of such things. I understand it is on the wiki.

Here is a link that has the code, I have been using it quite successfully http://wiki.universal-devices.com/index.php?title=ISY-99i_Generic_Calendar_Using_Programs_and_Variables It's a little bit of a pain to set up but works great.

I wrote a second set of programs that uses simpler logic.  See the link below.

For you, you would have an if clause that was something like

 

If

$i.month > 10

or

$i.month < 4

Then

do whatever.

Thanks,..I will surely give this a try. Does ISY support nested IF...THEN statements? If yes, then what is the level of nesting?

 

IF

  something

    IF...THEN...ELSE

THEN

 something

ELSE

  whatever

Nesting is not supported. A layer of thinner programs and variables is needed to achieve that goal

"Nesting" is done more or less like this

 

If

something

Then

Run program 2 (if)

perhaps other stuff

Else 

something

 

Program 2 (disabled)

If

whatever 

Then

whatever

Else

whatever
