MultiSensor alert smart app alerts/control

I am looking to see if anyone has written a smart app for the following.

Here is what I have-

I have a multi sensor on a window, and I want it to alert me when it is open if the temperature outside or on the smart sensor is above x value.

Basically I am trying to monitor my kids windows to see if they are left open after x temperature so we don’t turn on the AC. Eventually I would like to have the app alert me but also not turn on or off a certain switch (which will be connected to the whole house fan)

Thanks in advance if any has a framework I could leverage to write the app.


In the IDE, create a new smartapp and click the browse smartapps in the top right corner. You will see the code for “its too cold” you can reverse this for rising temperature. You can also put in a condition for the multi sensor having to be open before it alerts of the temp. You can get the sensor contact code from “left it open” app.

its a rough go at the code for this. I hope others can polish it for you.

You rock thanks… Ill play with this and see how it work.
