The part I was referring to was the addition of checking whether the lights were off as part of the IF portion of the Rule.
So instead of only checking if the door opened, you then also scroll over and find your light in the list of devices. After selecting it, you select the Off icon. Having both items in the IF portion of the Rule means that both must be happening for the Rule to trigger (both are true at that moment). If one is not (the lights are already on for example) then the Rule will not happen.
So what you end up having is two devices in the IF portion of the Rule. After those are both there (their order does not matter in the IF section at this time) you need to create the THEN portion of the Rule. This will also have two pieces, but they are both for the light you are using. When you are adding things to the THEN portion, order does matter. So first you want to select the light, then the On icon for it. If you saved it there, the Rule would turn on the light if the door opens and the light was off to begin with. But you also want a second step. You want it to turn the light back off after it has waited for a minute (I assume so people can walk through the area). So what you need to do (before saving) is add a second step to the THEN section. Since you already have the light showing, all you need to do is select the Off icon. This will add a second step to the Rule's THEN portion at the top of the screen. Just to the left of it you will see an extra box that says Wait. If you select that, you can tell it how long you want it to wait before it runs that step (up to 5 minutes). Set the wait and save the Rule.
So what you end up with is a Rule that triggers when the door opens and the light is off. It tells the light to turn on immediately, then hits that wait portion of the second step... waits however long you set it for (a minute) then it runs the second step, turning the light off.
The Rules are pretty darn useful once you get the basics learned. There is still areas for improvement and some things need some... interesting... workarounds to accomplish, but it is possible to do many interesting things. As you have more questions or if you want to post the things you learn and have worked for you, please do!
