I am looking for a SmartApp that will turn the Dehumidifier on when the humidity level reaches a certain % and then turn off when it hits the target %. Ideally I would like to do this during certain times of the day only.
Anyone have something>?
I use this. As my office has an AC installed as well, I added the option to start that up as well when the temp was above a certain minimum and RH was high.

}Oh, btw. The code has a bunch of sendPush statements that I used for mostly monitoring/debugging. Remove or replace with log.debug at will 
Can you post the code without the scroll bars, I cant copy and paste. Thank You!
@cdikland Edited your post to display code block instead of a block quote.

Thank you very much. How did you do that? Always bugs me when I try to post code and end up with such mess.
No idea how but obviously it possible as Tim edited my post. Be sure to thatnk him
When you create a post with code you select all the code and then his the </> button.

This can also be accomplished using the SmartThings channel in IFTTT.
