Using random to position curtains in RM5

I have a rule that detects when I have left my home, that sets my curtains at a random position.

I want the position to be random between 50% and 20% open, and not close.

In my current rule, they can close since random can select 0%.

Here is my rule:

How can I restrict the range of random numbers?

Create 2 local variables: range (=30) and position (=any number).

Then do this:

You could also use a third local variable (“minimum”) and use that in the second action (increase ‘position’ by ‘minimum’) if you want everything controlled by variables.

random(25) + 25 would get you 25 to 50, if that is close enough.

Thank you!

I tried both methods but went with yours, and it was just what the doctor ordered!

The position when I am gone, is not critical. I just want the “gone” position to be different each time to give the “is he really gone” look.

I set my range to 50 and the addition to 5 so the minimum open could be 5 and the max could be 55.

I don’t want the curtains to be open all the way to 65 when gone, but just enough of a difference.

Thank you both for your inputs!
